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

So a wet test to see how much the comp changes.

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
