Compression Test

lmmr74 · 07-05-2012, 09:13 AM

Hello, i just did a compression test on my 89 Supra Turbo (7M-GTE), and i got the following results:

Cylinder 1 12.5
Cylinder 2 10.5
Cylinder 3 11.5
Cylinder 4 10.5
Cylinder 5 11.5
Cylinder 6 12.5

Can someone help on these numbers?? Are these ok? I am confused because on the technicall manual, it says taht minimum compression is 9, and normal is 10 or higher, on the other hand the guy in the auto store told me that should be around 8.4...
Thanks in advance for your help!!
