can someone explain this results:

Compression

1 = 95
3 = 90
2 = 105
4 = 100

Leakdown

1 = 80/72
3 = 80/65
2 = 82/70
4 = 82/75

from 2002 wrx

 

LIC or GST can do a better job at describing the details but just from looking at the compression numbers something is VERY wrong.

you should see around 150-160psi on compression for the 2.0L WRX. The 2.5L motors with a drive-by-wire throttle body give a bit lower psi on compression I believe due to the throttle butter-fly valve not opening.

I would guess that you at least need a new motor but again, LIC or GST can answer that better than I can.

 

If you'd like PM me an email address and I can find my pdf file of SOA's compression check instructions/guide.

But yeah I agree with mcdrama...something sounds bad there. The compression is too low

 

maddhatteroo7 you have a pm.

 

PM'd you back
