Hello,
I swaped an s14 sr into my s14 about 6 months ago. the car runs like a champ and everything works fine except there is a noise like a rattle coming from the head. the crazy thing is that it only does iit when the car is in nueteral or at idle with the clutch in when in gear. If I put any kind of load on the on the engine and let the clutch out, the noise goes away and it purrrs like, well like a cat i guess. nobody i have talked to has helped too much so far. heavythrottle claims it is a sticky lifter, but through my experiences with them i've learned they are usually full of shit. anyone have any ideas.

p.s. this is a little far fetched, but i have a tomei adustable cam gear on the exhaust side, the motor came with it. could the gear be so advanced that it is making the rockers click? like i said this is a stretch of an idea,but i've tried and given up on pretty much everything else

i guess the lack of response means no one has any ideas?

I had a somewhat similar situation happen a few weeks back. I did a chemical oil flush and changed the oil and filter a couple of times and the sound went away. It sounded like it was a stuck lifter.

the sound has gone away a couple of times, when i first got the motor running i was breaking it in with 20w30 and lucas oil. this made the sound go away for a while. then it came back. a friend of mine was worried that the stuck lifter might get worn down from tapping so much, i wonder if thats what happened to mine.
