1997 Jeep Wrangler 2.5 liter 4 cyl. exhaust leak

Hello all,

slightly new to the forum but i have a 97 wrangler with the 4 banger. i have what sounds like the timing chain slapping the cover. it has 146000 miles on it and i am going to replace the chain and everything this weekend. but i am also having what sounds like an exhaust leak. i cant find leaks anywhere in the line. Could it possibly be the donut gasket? Anyways i need some help identifying that problem. Could it possibly be linked to the timing chain? (the noise that is). Thanks in advance for the help!

When you eliminate the timing noise then you can find the exhaust leak

My 99 TJ 4 banger was leaking. I thought it was the donut gasket but it turned out to be a stripped out exhaust manifold bolt. I checked the bolts to see if they were tight and one of them was finger tight. then I noticed it wouldn't tighten. Installed a helicoil thread repair and fixed mine.

The exhaust studs are often broken off on these engines. Keep looking and you will find it.
