I had a tester and I wanted to know how the rings ended up sealing. It's the same reason I check the tire preasure every couple fill-ups, because I don't know what it is. Don't you think it's a good thing to know?

 

I would drive it a little more.
#'s are consistent.
I think the rings aren't fully seated yet.
Synthetic oil takes forever to seat rings. Especially if you drive it off boost all the time.

Test it after 5K and results should be different.
If you take it to the dealer. They will say the same thing.
Don't worry about it.

I agree

 

I ve have performed a compression test on my 03 Evo8 and the results were as following:

1- 130
2- 115
3- 120
4- 145

I did the test after the car was stoped for 20 min, did not did it with 100% throutel on and did not do the test with adding some oil to know the differance..........PLEASE ADVICE

 

did you know this thead is almost five years old?

 

you NEED to have the throttle open. Those number are meaningless

 

Disconnect the connector behind the oil cap (crank sensor connector). Have engine warm and throttle opened fully. Turn engine for each cyl until guage quits increasing (about 6 cycles). Post results.

Also, dont pour oil down in the chamber for trivial reasons unless there's like a 15% difference, it can create preignition hot spots on surfaces.

You will have to reset the SES code for the sensor
