exhaust manifold ?

[bluepacecar]

do the exhaust manifolds warp in these trucks? the rt side is doing the ticking but its so faint i can only hear it when i give any throttle besides something (echo). i replaced the gasket already and am hoping its a warped exhaust manifold. autozone has them for 109. just wondering if its worth it...

anyone?

Never heard of this. Time for some headers!!

I have a set if you need them. Usually cast iron will crack before it warps.

stealership that i went to get the gasket said they can warp. can i reuse the gasket i just bought or is it a one time deal

 

[runs2rch]

The factory ones are reusable.

thats good i hope its a manifold then, and i retouqed the plugs first.

Actually, I have stockers off my 2001 L in my garage collecting dust. PM with an offer if you need them!!

my consirn is that its not internal and only a manifold issue.

IMO I'd first check that you don't have a loose spark plug.

IMO the iron manifold would not be warped...

I had a F150 that had a issue like yours, turned out to be one of the spark plugs had been over torqued and finally ended up loose. (Stripped threads)
Results were to re-tap threads

ive eliminated the plugs. did the gasket. so my only other option is order a new manifold. i even rechecked the manifold to make sure it seated in place 3 times.
