Topic: Broken Exhaust Manifold Stud (rear)

Thanks for the info David.  I've added it to the FAQ.

AS to the plastic spacer,
I believe it is to solve the broken studs on the manifold,
The head bolts are cheap, $3 to $4 each,
the head studs, are the expensive one's,
you don't even need them,
they just mount the wiring harness and one ground,

Hey Jeff love the new look

Looks like the Studs aren't that expensive actually.  The bolts were never really the problem.  Those front and rear studs are although I've never had that problem.  I'm not sure what really causes it other then the different expansion and contraction rate of the metals used.

That is pretty much what I have heard.  When I picked up the head from the machine shop, the shop manager pretty much said the same thing, that the header and head move due to heating and it shears the studs off.  If I remember correctly, both of my bolts broke on cold mornings (cold for Florida that is HAHAHA).

I suspect that with the new Banks header, it won't happen.  I think the full length gasket might make a difference.  The OEM exhaust header is installed without a gasket.  Only the Intake has a gasket.  Go figure.

Well, I am installing everything today.  I will report back this evening.

cya,

Your welcome.  Glad I could contribute some useful information.

Well, I have it all together and everything looks good.  I didn't encounter any  problems.  I followed the service manual and the Banks instructions.  The Banks Header bolted right on, without any problems.  It fit perfectly.  Actually, it is pretty much a precision fit.  There AIN'T no slop in putting it on.  You gotta get it straight or there will be problems trying to get the #1 bolt to thread.

So far, no error codes and the water and oil are being nice to one another.  It was pretty scary to crank it for the first time.  Once the fuel system pressurized, it came to life and just hummed.  I drove it a few miles already, hammering it a little bit.  It definitely has a bit more "go" in it.  Although, it is difficult for me to tell how much is new and what is a result of getting my CLOGGED cat and muffler replaced.

I will try to get the write-up online this weekend, with pictures.

Oh, it took me about 10 to 12 hours to get everything reinstalled.

Good night,
David

Folks,

Here is my Banks Exhaust write-up.  It is PDF, so you will need Adobe Acrobat Reader.  I may end up putting it online as web pages, but for it is PDF.  Enjoy!

Cheers,
