Sohc uses hydraulic rocker arms. You sure its not a bent valve?

Timing chain slap?

NIK90s13 · 06-20-2006, 06:25 AM

Is the oil clean and full? That will cause lifter failer.
Can you pinpoit where the tap is? Frunt back ect...

240sx=fast · 06-20-2006, 01:42 PM

not really,i just bought the engine and the guy sent me a video file of it running.i was thinking that it may be a sticking lifter because it does it only when it is first fired up,after it gets warm it smooths out.and the engine runs a little ruff when it is cold also.

it can be the timing chain guides. then tend to make that sound. it is a very uncomfy sound

240sx=fast · 06-20-2006, 02:01 PM

ya it doesnt sound very pleasant,lol

CaoBoY · 06-20-2006, 02:50 PM

if it is the timing chain guides, then you should probably just get a timing chain kit....i had a slapping sound when i would first start up my car....found out...it was my timing chain guide...it broke, and was sitting in my oilpan.

240sx=fast · 06-26-2006, 02:38 PM

well just talked to the guy,and he said that it doesnt go away..........it just gets a little more quiet.......can this be a collapsed (sp?) lifter?i got a complete second head if bad comes to worst,but i just need to know how to eliminate some of these probs......

NIK90s13 · 06-26-2006, 06:53 PM

Pull your valve cover and check the timingchain and guides, check the lifters too, if you rotate the cam till the valves are closed you can feel each rocker arm to see if there is to much play.

240sx=fast · 06-26-2006, 07:20 PM

do you know what the tolerance should be?

NIK90s13 · 06-26-2006, 09:36 PM

No, Hit the serch for factory service manual, down load the single slammer. I have a dohc motor (kade) and manual, I swaped the sohc motor out, I didn't have much intrest in it sorry.
I just serched and found this link, check it out. The hydrolic lifters don't ajust, so if you have slack then it is shot and you need new ones, hope this helps.
