I have a 1998 Prelude SH and recently have noticed some sort of knocking or ticking noise coming from the engine. I have done a valve adjustment, checked condition of the LMA's, and replaced the plugs and wires. It felt like a LMA on the intake side of cylinder 3 was a little sticky but not much different than any of the others. I have had 2 different mechanics listen to it and they both said it sounded to them like a knock coming from the head which makes me think it's an LMA from the research I have done. Today I used a stethoscope and think it is probably coming from cylinder 2 or 3 in the lower portion of the head. I have also pulled each plug wire and the noise did not stop when I pulled any of them so I do not believe it is rod knock or wrist pin knock. Also it has been idling very low, anywhere between 300-500. Not sure if the low idle is related or not, but compression numbers are all in between 10% of each another so I do not think it is a bent valve. Any help would be greatly appreciated. Thanks!
