92 Vx with a H22a4 Hasport mounts.
except idle & random/occasional knocking sound car seems to be running fine.
no codes, vtec is working.

as fas as the idle...it idles around 800...for about 30sec-1min then it drops to almost stalling out..bounces back & forth between 100-800 for about 10-15sec then comes back up to a steady 800 for about 30sec-1min & does it all again.

IAC seems to be pretty clean ...have played with idle screw.
can't figure it out.

now this sound isn't constant...it will make the noise for about 30sec-1min & then stops...& when it happens is random
it sounds like is coming from the timebelt?? belt lash? belt rubbing the cover?

one thing we did mess up was we found out there was too much oil in the car for about 100-150miles of use..probably about 6-7qts?..that plus a bad valve cover gasket caused some oil leak.

would this have cause a problem.
maybe oil got over onto the cam gears & belt & causing a problem?

anyone seen/hear/or have this problem.
