Low Compression??

[Mike_Shepard]

I just did a compression test for the heck of it and I wond up with 123Lbs in all 4 Cylinders. Is this right? for a T2 2.2. Seems alittle low

That sounds perfect. Mine were all 120. I believe once they drop below 100 psi then its time for a rebuild. You have to remember on our turbo cars we have a low compression to begin with

Yep, sounds good. A really tight motor might give 135psi, but around 120 is more typical for an engine with some mileage.
