Weird engine noise

Do a Compression Test....Cold/Warm

Does it idle funky, or lack acceleration power?


ALL 3 1 8's have nylon camshaft timing gears and WEAR.

I ALWAYS replace the timing chain and gear with double rollers when I own/drive 318s for this "weird noise" reason.

I also Use a Mopar Performance Timing Chain Tensioner for even more assurance.
