Reproduction small block exhaust manifold
 

I remember a while back when someone was saying small block repop exhaust manifolds didnt fit. I just installed a repop driver side on a 69 Z28 it fit with no problems I didnt even use a exhaust manifold gasket and it didnt leak. It was bought at D&R one of this sites sponsors.

The early repops did have problems. Helping a friend, I couldn't get the damn things to stop leaking no matter what I did! Sounds like Steve at D&R has resolved the issue.

Thanks for the heads-up. https://www.yenko.net/ubbthreads/imag...lins/beers.gif

What casting date does it have? I was told they were all the same, but maybe a different batch now and different date?

Yes the first batch might have had a problem but they fixed it. The date I believe was E 69 this way the E could be altered for a I or L

Re: Reproduction small block exhaust manifold
 

Will the manufacturer replace the early junk? I have some early ones, and the driver's side is absolute junk. The manifold hits the head bolts, the block, the engine mount.... etc.... I was looking for a single original one to replace it with, but if the latest offerings are better https://www.yenko.net/ubbthreads/imag...ns/naughty.gif

[/ QUOTE ]John I installed them on my Z with no problems.. It was kinda nice not having to start all the bolts and trying to get the last one in because the manifold warped over time with heat.. Plus, GM didn't use "I" for marking parts for the months because it looked too much like a "1" (one).. Mark

Re: Reproduction small block exhaust manifold
 

I agree nice fit on the new ones. Install, fire up, no leaks = https://www.yenko.net/ubbthreads/imag...mlins/cool.gif for the $.

Re: Reproduction small block exhaust manifold
 

What is the casting date on the new repops? Still E 6 9?

Thanks,

GM did use the "I" for september exhaust manifolds. I know "I" wasn't used for some parts, but it was on the exhaust manifolds.

Delco-Remy was the manufacturer who mostly didn't use the letter "I" when date coding parts.
I too have seen Ex. Manifolds with the letter "I" cast in their dates.

I'm so frustrated with these mani's that maybe I will just buy another repop set! I have ground so much material off the backside to make it seal that the mani will probably crack sometime down the road - and it still leaks https://www.yenko.net/ubbthreads/imag...emlins/mad.gif I know that I bought my set along with C-Joe's set, and I think both of ours leak https://www.yenko.net/ubbthreads/imag...lins/frown.gif

Re: Reproduction small block exhaust manifold
 

Yep...Marlin, I think its time to buy another 2 pairs for the same pair of Deuces.

Re: Reproduction small block exhaust manifold
 

Who did you buy them from I would call and see what they can do for you. It doesnt hurt to try and see. If it was D&R let me know Ill see what I can.

Good idea, hate to burden the seller with a mfg defect - but I'm so frustrated with these things I feel like melting them down for scrap! I believe the passenger side is also incorrect, causing the head pipe to interfere with the trans crossmember. Both Joe and my car have the leaking driver's side mani, and the pipe interference on the passenger side. Neal and I gave the poor Gardner guys fits about the head pipe, and they provided the necessary solution - when later I began theorizing that the culprit was a faulty passenger side mani as well https://www.yenko.net/ubbthreads/imag...emlins/mad.gif can I get steam to come out of that smiley?

I think we bought them from Camaro Specialites in Aurora, NY.
