Lame'O compression test question......?
History: 98 Talon, Tsi, AWD, Modded.
Had a SBR Bastard 20G on last year and the turbo blewup after about 90 days. SBR pulled it apart and CLAIMED the "something must have broke free" in my motor to cause the serious damage to the Exhaust side turbine. I never had it apart myself, so I'm still not sure what really happend. We ended up splitting the difference on the repair, So I bought Tom's FP Big T28, and sold the newly rebuilt "Bastard" right here on the style board for 1/2 price of new.
I finally got around to running a compression test tonight to try show me if my motor is really screwed up or not before I throw on this good T-28.
According the FAQ, the motor should be at operating temp for the test, <which it was'nt as the turbos off from it> and it hasn't run in about 4 months now.
Anyway the results I got were as follows.
On cyls 2,3,4, the VERY first "pop" of cranking the moter I got 120, and the 2nd rotation it went to 150 and held there. But on cyl #1 the very first pop gave me only 20 then the 2nd gave me 150 and held?
I ran the test about 2-3 times on each cyl and got the same results each time.
The one thing I didn't do was hold the throttle open during this testing. still not really sure why you are suppose to either?
Please forgive my lameness at running compression tests, but what would results like these indicate to you guys?
The only one that could be suspect is cyl 1, but the question is to what degree?
Thanks in Advance........
Howie
