Hey guys, my little 2.5 is annoying the hell out of me. Has the tick that ive found to be a common issue. I did a new timing set and tensioner, (tensioner was JUNK), new ex manifold (broke) and the noise is still there. First few seconds of running its silent. If I get on the gas at all the noise goes away. I switched to a heavier oil and swear it got worse!! My only other symptom is very low engine power, but I believe I have that narrowed down to a weak fuel pump. You guys have any suggestions before I dive any deeper? Thanks!!

Got same noise and my motor is a fresh rebuild. My buddy had this issue and found that filter on fuel pump clogged.

Well I know the check valve in my fuel pressure regulator is shot. A complete fuel pump is only 50 bucks more than the regulator alone so that will take care of my filter as well. Who knows, a new pump might fix a lot of my issues. I'll keep you posted! The noise just drives me nuts..
