The best way I can describe it is almost rocks in a dryer, but more so a piece of paper when you stick it in a fan except slower. I recently got my 60k done and I guess there isnt anything wrong. I am running rich- chipped p28, but other than that there is nothing out of the ordinary with my set up. Any thoughts on the sound would be appreciated. If you need more clarification let me know.

Wow just stay out of my thread.. someone who doesnt know what WOT is, has altezzas, and is trying to put v-tec **** on his ls... good job, and what you said has nothing to do with my post... maybe i didnt clarify... but its coming from my engine... hence engine bay. anyways anyone else?

 

could be many things:

1) detonation: due to lean conditions or too advanced timing

2) engine knock: spun bearings due to oil starvation

3) exhaust leak: n/a


diagnose detonation by using higher octane fuel and/or retarding timing until noise goes away

engine knock is tougher. if its not detonation and not exhaust leak, pray you did not spin a bearing....b/c engine rebuild time.

how do i know if i spun a bearing or not and what exactly is that?

 

Ok, let's start simple. You said you just had the 60k done, right? And it started after that right? Do you know your mechanic? He might just be an idiot and put too much clearance in your valves, hence the "rocks in the dryer" sound. Can you isolate the sound? Does it sound like it's coming from your distributor, like the bearings gone out? A loose timing belt will cause that sound in any DOHC Honda engine. There's a tightening procedure in the service manual: #1 TDC, loosen the tensioner pulley bolt (accessable through the rubber plug in the lower timing cover) and re-tighten. Then spin the engine 90* counterclockwise and loosen and tighten the bolt again, and viola: your timing belt is readjusted. If you've resurfaced your head, it will be difficult to get the right tension on your belt.

Honestly though, I think it was just lashed incorrectly during your service. I'd take it back and verify the specs. (in: 0.17+/-.02mm and ex: 0.19+/- .02mm).
