Well thats a bitch. Next oil change try a different brand.

 

I've got that problem when my engine's cold. Right now I'm just kinda suckin it up and livin with it, one day whenever I get some money I'll be upgrading to RPW stage 1 turbo valve spings. Until then it's oil additive, change the oil often and baby the car when it's cold.

 

I have a lifter tap... Oh wait that's cuz I have mechanical lifters... LOL
