i finished my SR20DET swap and i started my car and my valves are very very loud, is that normal?? i drove it twice around the block and i thought that maybe once oil got into the valves it would go away but it didnt yet. Whats going on with that? Is that a normal thing for SR's? Please help..

you sure its a valvetrain noise?....is it a loud ticking noise coming from the intake side?

lob@ller · 01-12-2008, 10:12 AM

Did you bleed the lifters?

Xracer · 01-12-2008, 10:13 AM

did you take the head apart? there are shims on the rocker arms that adjust valve clearance, if they are out of spec they will cause noise.

no i did not bleed the lifters?? how do you do that?? and do i have to do that when i fist swap my car??

ecuastyle84 · 01-12-2008, 11:05 AM

put them in oil and find some thing thin enough to bleed the lifters...the lifters should compress when you bleed them...there should be a hole on top the lifter and i think there was a smaller hole in that hole and then the ball bearing. So look for the thinest thing you can find to bleed them

how do u adjust the clearence??

tknbkthrsdy4anfg · 01-12-2008, 11:56 AM

They do it hydraulically. Oil pressure pushes up on the lifter and keeps the rocker in constant contact with the cam.

Sometimes injectors can make a ticking noise that sounds like the valvetrain. Although it's usually not very loud. Anyway bleeding the lifters is not very difficult. Just a little time consuming. The write-up in this thread is good.
