Re: leaking exhaust manifolds

I would just pull the manifold and have it trued up. There are also gaskets available but I would get is true first.

Re: leaking exhaust manifolds

Coat them down with (bolts) some anti seize spray WD 40 or PB Blaster...I would do it over a number of days prior to tackling the job.

Mine on the rear of block actually popped the bolt heads off the manifold (driver's side) and the remainder of bolts had seized in the manifold. I was able to cut the manifold bolts off with a sawzall leaving as much stud as possible. Went to Sears and bought some stud/bolt extractors not sure what they are called.....look like a socket with spiral teeth inside to grip rounded boltheads or studs...worked awesome....on re-install use a quality anti seize paste....

Good idea Tom to resurface manifolds....I used the gaskets and has worked fine.

Re: leaking exhaust manifolds

Just got done doing mine. Like JCart said SOAK them with PB blaster for at least a couple of days. all mine came right out except for 1. the third one from the back on both sides is a PITA. For some reason the hole where the bolt goes thew the manifold is smaller then the rest and likes to seize up. If it isnt turning heat up the manifold and it will come out. I planed the manifolds and used IH gaskets

Re: leaking exhaust manifolds

I was at the stealership today and they had no idea about the gaskets, I will see if one of the local machine shops can work on them

Re: leaking exhaust manifolds

I may take you up on that set Allen then I can get them surfaced, blasted, and coated. I may still put the gaskets just to make sure

I have been soaking them every once and a while getting ready for this
