i just got a valve adjustment yesterday, and now it idles wierd....

the rpms stay consistent at around 700-800 but instead of it sounding like "burrrrrrr", its more like "bop bop bop bop" and shakes alot

is this because the valves need time to settle? if so, how long does it usually take for the valves to settle?

 

sounds like the adjustment may be on the tight side.

 

Yes it sounds like they are on the tight side. The noise should go away within 24 to 48 hours if the car is daily driven, if after a couple of days this continues, I suggest you check with whoever performed the job.

hth

 

sounds they were adjusted to tight. I would take it back, or do it yourself, it is really easy to do...

 

i took it to PYR (peter yem racing) and they know their ****, so im probably gonna give it another day or two. peter said that they'll settle, but he didnt say how long.

 

make sure they do the valves adjustment when the engine is cold

 

first off all did you
try and reset the ECU !!!

did a valve adj. on a B18C5 and the thought i mees it up !! cause sounded REALLY wired and and when you hit the pedel it was worse !!! then i tryed 2 reset the ECU !? bingo.. never ran that good bofore !!!

 

haha, completely slipped my mind...im too lazy right now, tomorrow mornings a good time, i'll let u know... thanks peeps!!!

 

Is it bad for the engine for them to be a little tight? Any ups and downs?

 

Well at the extreme, if the lash is too tight (small) then when the motor heats up you may have a problem where the valves aren't closing all the way which would lead to a loss of compression.

 

yeah plz do !! ;-)

 

When I first adjusted the valves on my GS-R, I fudged one and left it with about .030 clearance instead of .007 I don't know how we missed it. Anyway, the car sounded like a diesel at idle, shook pretty bad, too. I ended up driving 200+ miles like that. Then I went back in there again and found the loose valve, adjusted again, and no problems.
