Default Engine Noise

I finally got her running. The engine seems to run ok. New oil pump works fine after shaving off a little metal to allow clearance for the timing gear. I bought this car without hearing the engine. It had a crank keyway problem that cause the timing gear loosen and grind into the oil pump. I jbwelded the new key in and put loctite 660 on the crank surface the timing gear goes on. I ran it yesterday and the engine sounds like a diesel. That is the best way to desribe the sound. I does it at idle when cold, but goes away when warm. When warm, Under heavy accelleration is goes away, under decelleration it comes back loud as heck. At first, I was thinking "rod bearing play", but not sure, maybe valve train. It is a substantial and loud sound and does not sound good at all. Any ideas?

Check valve lash clearance first of all.

will that make a diesel like loud racket? I did check my timing, it was 25 degrees BTDC, I adjusted it to 5. That made some difference, but the problem still exists.

You should post exactly what kind of car you are running, 8v/16v, year, 4wd? etc. Put it into your signature so people know what you're talking about without having to search around.

I replaced the timing belt cog and timing belt. I was very careful to have the crank and cam sprocket marks aligned when I put the belt on. I got it on the money. I am not sure why the timing was so far off. Anyway I have it to 5 degrees, but my issue still persists (see above). I did check the lash on about 4 different valves just to see and they were all right at .008", which I believe was in spec, so I did not bother wiht the rest, not to say that there is a problem. I think setting lash would be worth a try, but that sound is so loud and diesel like, I would be surprised if the valve lash really is the culprit, but it might. I was just trying to see what it could be based on the symptoms I have described above.

I would suspect either valve lash out of adjustment or valve damage resulting from the original keyway problem. If it were my car, i would check valvelash per kickfix's pages, then a compression check. The compression check would most likely give you an indication of whether you have valve damage. Bad compression = bent valves (most likely from keyway damage) but other possible causes too.

Check and set your lash, then do a compression check and report back your findings.

good idea randy. What should I expect in PSI for compression test? 140k miles.

170 on all four, taken with all plugs out and Fuel Pump Relay defeated, is a nice reading.

For more thorough information on Compression testing and Valve Lash setting, check KickFix pages: The KickFix Repair Pages, for Sidekicks and Trackers
