Thanks for that. New to this stuff so just trying to learn

Ok, i redone the test but this time with the throttle open and engine is at operating temperature.

DRY:                     WET:
1 - 195                  215
2 - 195                  215
3 - 185                  210
4 - 195                  210

What do you think? Overall good for its age? 258,000.

The 4age manual states 179 psi but i'm unsure whether its for the redtop engine. Thanks heaps

Hey everyone,
I just done a dry compression test on my daily corolla sx (4age red top 100kw) with the throttle closed. It is smoking and burning oil =(

You think the below numbers indicate the piston rings are okay? Just trying to determine whether its my rings or valve stem seals. Thanks!

Dry test:
1 - 160
2 - 165
3 - 165
4 - 160
