Title: Engine noise
Post by: Anonymous on May 09, 2005, 08:04:25 PM

My 4.0l TJ seems to have developed a noise that I was not aware of before I changed the exhaust manifold. Difficult to describe and not being particularly experienced mechanically (but keen !) how would I go about diagnosing what it is? The best I can describe it as a 'ticking' sound but not like tappets ?!?! I have recorded a bit of video so that you can all hear it, but dont know how to attach it to this message, failing that happy to email it to any of you whizz kids [/img]

the ticking is amost deffo going to a slight blow on the manifold i am gessing its loudest when the engine is ticking over cold and gets quiter as it warms but you can also hear it under aceleration up hill

Yep, that ticking is the first thing most people hear when the manifold begins blowing.
Did you clean off the old gasket off thoroughly?

do them in order again and give them a quarter turn and see how it is you may just have dinked the gasket and need to go over the fun again

Did you paste exhaust sealer on the gasket, both sides?

The studs/bolts have to be spotlessly clean or you may get a false reading from the torque wrench.
