| Today i did a compression test on my 90 Z TT. The car had 112k on it, ive had it for over 3 years and changed the oil every 3k miles. i bought the car with 80k on it. in the past month its been burning oil out the drivers side. So i did a compression test just to be sure its the turbo. After took the balance tube off i noticed oil in the intake manifold, not alot but it was noticable. the results are: 1: 152
2: 151
3: 151
4: 150
5: 152
6: 150 If i go by Ash's autofaq post these numbers are right on the border line. I just wanted to get some people comments before i spend money on buying turbo's when i should buy a new motor. This test was done with the motor warm(i think the motor migth have cooled a litle while i was disconnecting everything) and throttle bodies fully open jerry
