I picked up a 97 Honda Prelude Type SH and the seller believed it had rod knock.

I drained the oil and fished a magnet in the oil pan. There was no evidence of any metal shavings typical of a bearing failure.

The noise is coming from cylinder 1 in the head. I checked with a stethoscope to pinpoint the noise.

So far I've adjusted the valves to spec. Intake at .007" and Exhaust Valves at .008". During the process I didn't notice anything that was damaged or looked/felt out of place.

Wondering what I should be looking for now. Bad LMA? Any common valve train issues with the H22?


Here's a vid...skip to 1:45 or around 2:00 and the noise is very audible. Don't mind the oil leak dripping onto the header, I didn't tighten all the valve cover nuts completely before shooting the video.

TIA
