Exhaust Manifold Replacement

[SafeAirOne]

After installing the manifold the truck now sounds like crap. seems like alot of valve noise. I torqued everything down as per the instructions and installed all bolts in there previous locations.

Valve noise? Like a ticking? Not sure how manifold work would affect the valves. However, an exhaust leak at the manifold = loud ticking sound.

I'd get a length of vacuum hose, stick one end in my ear and probe around the manifold area with the other end till I found the leak, were it me.

Any exhaust leak will make it sound like its ticking. Usually a culprit is the joint to the exhaust pipe. The ball and socket of this must be cleaned and I use some exhaust cement to make sure on these. Rust and old hardened crap will make it impossible to seal properly once removed.

Note to self: must tighten up mine as it has left black spots on the down pipe.
