427 engine (part 2) - RHS block

Yeah, that hood looks pretty nice, but I'm not quite to the point where I'm ready to start thinking real hard about it. Still got a few more minor things on the car to finish up before that happens. Didn't the stock 2004 Z16 model come with a carbon fiber hood?

Yes it did. Mine is a carbon fiber hood from the factory.

Is the 2004 commemorative version the only one with the Z16 designation, as I think it's the only one that got the CF hood. But I don't know if it'll help any clearance issues you may now have anyhow.

No the C6 Grand Sports are also Z16's and so is the 1965 Chevelle SS 396 of which only 201 were made. The Z16 is the holy grail for the Chevelle guys. I saw on in person in '08 in WPB sell for $177K. There may have been a few others along the way. I am not sure if the C4 Grand Sports were Z16's or not. The 2004 Corvette Z16 was the first to get a CF hood from the factory. After that the C6 were CF front ends. I am not sure what years and models of the C6 have a CF front end/hood though.

It will not help with the clearance issues as it is the same size and dimensions as the stock hood just made of carbon fiber with some stripes on it. The guys that are modding the Z16 with roots sytle superchargers had to change the hood out just like the stock guys.

Ouch.....

Yeah, I know one day I won't be able to drive a stick shift at all, but I'm hoping that won't happen too soon. Damn old age crap.....

I hope both of you get better.
 
Just kind of twiddling my thumbs waiting for the hood struts to come in. I did get a set of stainless struts from MidAmerica but they have the same threaded connectors that my old ones have, and they didn't seem to last very long when people took to being a bit rough with opening the hood. So I went and ordered a plain vanilla set of OEM struts.

I got to thinking when bringing the car home from Aaron's that the console lid didn't seem to close and latch, so figured I could take a look at that now that major things seem to be out of the way. Well, yeah..... Looks like someone slammed that down too hard, or else jumped on it, as the latching mechanism was laying down at the bottom of the hole in the first pic. I was able to fish it out of there (so at least I don't have to pull the console out to get to it) and someone just broke the end off of it, evidently by pressure from above.

I found a replacement online and ordered one to fix this particular problem.

I guess it would have been way too much to ask for the guys working on my car to not abuse it...... :rolleyes:
 
Yesterday (Friday) the new hood struts came in, so Connie helped me put them on the car. I got in both some stainless steel ones made in Turkey, and OEM stock ones made in USA. I wound up putting the OEM ones on the car, as those stainless ones only had the snap on fittings on the ends screwed onto the strut itself, and I've already seen how poorly they seem to hold up. My one original strut has the bottom fitting with a swivel, but the new ones aren't made like that. But they seem to be much more solidly mounted and hopefully less likely to break loose if someone is careless opening up the hood on the car.

So I was able to change the oil and filter, and also replaced that leaking oil level sensor I bought a while back. I also checked the catchcan, and there was just a small bit of oil in there, so that appears to be working and doing it's job.

Now if it would just stop raining around here and my right elbow would get 100 % so I could drive the car a bit....

It still needs some minor fine tuning, as I noticed that it runs a little rough when started up cold, and when I turn on the AC. Mike has been out of town, and I haven't been able to drive the car anyway this past week. I've looked at the weather forecast for the next 10 days and I'm thinking maybe instead of fussing with this car I should be building an ark.
 
You know how some things just nag at you subconsciously, but you just can't put your finger on what the heck it is bugging you? Well, I've been concerned about an odd scraping noise that I've heard several times when starting off from a dead stop with this car. I was thinking that there was something wrong with the clutch, so honestly this has been gnawing on me for a while now, thinking I still had something rather major that needed looking at. But it just didn't make sense to me. When Mike Carnahan was here tuning my car, I never heard that noise even once while he was driving it. But when I took it out for a drive after he was done, I heard it plain as day a couple of times. And I distinctly remembered hearing it on the way back from Aaron's with the car back in November.

How could Aaron have heard that noise and not mentioned it or done something about it? It's not like it was subtle or hard to hear. How come I didn't hear it at all when Mike was driving the car? Then it dawned on me. I used the air conditioning while driving and Mike did not. As for Aaron, well, when I specifically asked him about whether the AC worked or not, he didn't know. When he tried it, he found that the compressor was bad, so he had it fixed at a local AC shop that he suggested to do the work. From what he told me, he actually pulled the compressor out of the car and reinstalled it, presumably because of all the stuff surrounding it that was not stock.

So today I went over to the garage and put the car up on the lift to poke around to see if I could see anything that didn't look right. Well, yeah.... This doesn't look right at ALL.



I'm guessing that when starting off from a dead stop, the engine torque caused this tensioner to twist and apparently rub against something, making the noise I had been hearing. I'm assuming the tensioner is likely shot so I just ordered a new one, just to be safe. And no, it's not simply a matter of a loose bolt, that bolt won't tighten down any further, so it is apparently too long for the application. Honestly, it baffles me my in the world Aaron wouldn't have noticed something like this since he obviously had to have been right in there to remove the AC belt. :confused: Even if the too long bolt was put in by Harwood, it should have been obvious to him when he loosened the tensioner to get that belt off of it. It's not like you can MISS seeing the darn thing.

Oh, and while I was looking over the tensioners, I noticed that the billet tensioner pulley I bought from Tracy a while back on the serpentine belt tensioner wasn't there any longer. Wonder where that wound up? :shrug01:

Man, you would think I would run out of things to find that were done wrong, or just flat out screwed up whenever I look closely at another section of that car. Yeah, I feel like I am out of the woods with my car, but these stumps I still keep stubbing my toes on are murder.....
 
With all of the ponies that you now have at your disposal, it's a darn good thing you discovered
this one. I'll bet that puppy was just waiting to come apart under WOT and scare the
living crap outta you! I recon the BANG would have been very loud! Those 2 guys
sure do give a bad name to mod shops and tuners!

Yeah... At the very least, it could have ruined the AC bracket over time. I think that is where the tensioner bolts into. Or it could be even worse if it bolted directly into the block and wallowed out and ruined that bolt hole there. I'm hoping that I did catch it in time to prevent that from happening. The bolt doesn't wobble, so I'm hoping the hole itself is OK.
 
Rich, I like the way you think! Little nagging things don't sit well with you, and I think
that this will go a long way to having a very reliable (not to mention F-A-S-T) C5Z when you're done.
I would be willing to bet that when it finally does get back on the road full time that
you've got all the problems solved that you have found or seen. There may be a few
that pop up, but they will be ones that you had no idea were coming, and couldn't
do anything about. Keep plugging............you'll get them all eventually!

Yesterday the latch for my console door came in, and that was a simple matter of just snapping the new one in place to fix that problem. So now my console door will stay shut.

Today I pulled out the oil dipstick tube, as I had noted that it was rusted where it was close to the header pipes, so I assume the heat baked the paint off, and then the bare metal rusted over. So I bought a new one a while back, and since I was going to be painting the dipstick handle (used to be chromed, but that didn't hold up through the gauntlet my car had to run the past couple of years), I figured I might as well paint up the new tube as well and use some high temp paint. So they are both drying right now and I'll be able to put them back in a couple days from now when the paint has cured sufficiently.

My order from Ecklers came in and when I looked that over, I noticed that the box for the AC tensioner was not sealed, and sure enough, the bolt that was supposed to come with the tensioner was missing. I called Ecklers and they are supposed to be sending me out a bolt. But that shot down my plans for replacing the darn thing today. In any event, I looked over the new tensioner, and for some reason the mounting hole just looked much smaller than the unit on my car. I looked at it more closely, and year, the hole is no where near the size of that bolt on my car. So getting worried that not only had I not gotten the bolt I was supposed to, perhaps I got the wrong darn tensioner. So I decided to pull the old one out to take a look at it.

Well, I can see why they were supposed to include a new bolt. The old tensioner's bolt has a sort of collar on it that fits in a slot in the tensioner. Of course, this one was wobbling like crazy, so it pretty much tore up the hole. And you can see scrape marks around the hole as well. Definitely shedding metal, as I got a bunch of tiny shards of metal in my fingers pulling that guy out of there. Kind of like those tiny hairs you get from cactii when you try to get too friendly with them. It wasn't all that tough getting the belt off of the tensioner, and the mounting bolt out, but that thing just BARELY fits between the front spring and the engine cradle. But any way, this fix is dead in the water till I get that new bolt from Ecklers. Hopefully it will be in before the weekend.

Another thing I got from Ecklers was a kit they offer to fix broken rocker panels at the point where it connects to the front fenders. I guess this is a common problem. I've had mine broken on the passenger side ever since the car was at Harwood's shop, and although Aaron did fix it for me while at his shop, well, I just really wasn't all that impressed with his "fix".

No to mention the hose clamp on that turbo pipe pressing against my fender making that noticeable bulge there.

screw_02.jpg


I fixed that way back when I had to move the turbo pipe out of the passenger rear wheelwell.

But in any event, I got the two pieces of plastic for this fix, but since my driver's side is still OK, I only needed to tackle that passenger side. After figuring out how to orient it, I used some 3M plastic bonding epoxy to bond the piece to the rocker. BTW, that 3M stuff started setting FAST, so I really had to hustle getting it layered in there and then putting the fixer piece in place. Seems solid, so I hope I moved quickly enough...

I still need the clip that attaches to that fixer piece of plastic, so hopefully I can find some at the hardware store. I looked through all my junk and couldn't find any spares laying around. But hopefully that will take care of that flapping fender....

Actually, looks like everything I started today is incomplete because I am waiting on something. :shrug01:

Oh yeah, I'm still trying to figure out what to do about that airbridge hitting the inside of the hood. I found an airbridge by Vararam that was suggested to me by Chris at Compcams that may do the trick. It also will relocate the MAF sensor to the front of the airbridge, right next to the throttle body. I asked Mike Carnahan about this, and he said relocating the IAT (incoming air temperature) sensor in that manner is actually a good thing to do. I don't believe we even use the MAF sensor any longer since he did the speed density tune on my car.

Ah well, I guess I'm going to be doing minor stuff like this for a while yet on the car...
 
Heck Rich, when you're all done with the car you're liable to go stir crazy!
You'll wind up bothering Connie so much that she'll tell you to sleep in the car.
Better plan on some "interior mods" before you finally get done with all of the
other projects! :D:D:D Like at least 1 seat that will recline the whole way. That
ought to be "trick".

OH NO !!!!! Field stripping a C5Z blindfolded. I'm gonna watch for the mushroom cloud
around the Crawfordville area.....:rofl1:
Andy :wavey:
Hiya Ken
 
I think Ken meant that I should try to put it back TOGETHER again while blindfolded. Perhaps he is inferring that this was the way the car was worked on between 10/27/09 and 11/18/11? :hehehe:

Nuff said and you are so right Rich:shrug01::shrug01:
 
I found a U-nut clip that would work in an assortment I bought a while back, so it looks like I have that fender tied down pretty well now...

It feels like there is still a broken tab up near the center of the front fender, but I don't think I could get to that one too easily. So hopefully this will suffice.

I went out to NAPA today to see if they had the AC idler pulley there, but they didn't have one in stock. I figured I might as well replace that while I'm replacing the tensioner. But the guy said it should be in tomorrow, so since the bolt hasn't shown up from Ecklers for the tensioner anyway, I figured that would work.

I ordered the Vararam VR Power Duct (http://www.vararam.com/powerduct.html) in the hopes that this will fix the airbridge clearance problem, so that is supposed to be here on Monday. If it doesn't, the guy said I could return it within 30 days.

Been doing some light wrenching and my right elbow is feeling better, but certainly not quite 100 percent. Looks like the weather is supposed to clear up for the weekend, so maybe I'll be able to drive the car a little bit, with any luck.
 
Well, I've been browsing through photos and videos I took of my engine trying to figure out what happened to that billet aluminum drive belt tensioner I got from tracy that I had on my original LS6 engine. I could see that it was installed on the new engine while at Harwood's shop while he was putting my engine together, but the last image I have of it is on 09-25-2010 just a week after it was towed to Aaron's shop. So sometime between then and 11-18-2011 when I drove it home, it vanished while in Aaron's care and a stock one wound up in it's place.



:shrug01:
 
Well, it appears that even minor problems are going to take big chunks out of my butt now.

Ecklers is claiming that the A/C tensioners do not come with a new mounting bolt, and you are supposed to use the old one. Yeah, right, how is THAT going to work?

Would have been real nice if they had told me about this on Wednesday when I called about it so I wouldn't have been waiting patiently for FedEx to show up with that bolt the past two days.

So, tell me guys, what is going on here? Did I actually have an OEM A/C tensioner on my engine and the replacement has just changed, or did someone put something funky there and the new replacement is actually what I am SUPPOSED to have there? Apparently I just can't assume anything about what those guys did with my car.
 
BTW, looking more closely at a photo of that old tensioner, darn if it doesn't look like the mounting hole in that thing is off center and possibly the recess somewhat egg shaped to me.

ac_tensioner_05.jpg


I just would like to know what CAUSED that damage to the tensioner. I suspect the bolt was too long, but heck, I don't know for certain. The bolt I bought at Ace Hardware is slightly shorter.

BTW, I'm sending that new tensioner back to Ecklers. I really don't like the way they handled this. I bought this tensioner from Ecklers SPECIFICALLY because it came with a new bolt as shown in their catalog. Their price was at least $20 more than other sources, but I was willing to pay it thinking I was getting what I saw in the photo (meaning NEW bolt, since I thought my original bolt might be too long). Since that is not the case, and I DIDN'T get a new bolt, then I am sending it back to them (on their dime) and getting another A/C tensioner from someone else. I don't like it when someone pulls a bait and switch on me. I wasted a week with Ecklers on this as it is. I ordered it on 06/09 and here we are a week later, they dragged their feet processing the order (they are located in Florida, and ground shipping is effectively overnight to me), then when I called on 06/13 (when I got the package) about the bolt problem I spent the past two days waiting for the bolt they said they were shipping out to me. Had I not called on Friday, no telling how long I would have been waiting for the FedEx truck that was never going to show up with that bolt. They didn't even bother to let me know it wasn't coming.

I've quite had my fill of crappy customer service, thank you very much... I've got another one on order from SummitRacing which is scheduled to be here today (Saturday). I've got another bolt from Ace Hardware, and as has been suggested will just run with that. I'm also replacing the other main belt tensioner with a CompCams billet unit and replacing the other idler pulleys as well, since I don't know if the original ones off of my LS6 were used on this new engine. The pulley on that A/C tensioner spins REAL easily, so they might all be original.. Well, I'm pretty sure the tensioner for the serpentine belt is likely new, since that USED to be my polished billet tensioner when it went into Aaron's shop and now is a stock looking tensioner. Heck, might as well replace them all right now. Why have ANYTHING old and/or questionable on my car?
