my 1990 integra rs has forged pistons(9.5:1) and rods. it makes a ticking/knocking sound. i had the valves adjusted, they were fine. i changed the oil, there was no metal shavings in the old oil. it still ticks/knocks. the engine runs great and there is good pwer all the way to redline. if something major was wrong with the car would it run fine? what could be wrong? HELP.

i had a few mechanics listen to it and inspect it. two told me to have the vales adjusted again. one said he thinks its a piston problem. i think its in the head cause thaats wear the sound is coming from. Anybody think anything else or agree with one of the mechanics? Please HELP!

 

but i changed the oil and there was no metal in the old oil.

 

if it isn't the rod bearing(i hope to god it isn't) what else do you think it could be? the sound is coming from under the valve cover.

 

thanks for the help.
