Message I have to replace my VGDE30 motor in my '92 300. I am looking at a motor on Ebay from Jspec Auto Sports in Virgina. They sent me a video showing them testing the compression. The test is a cold crank test and gave the following numbers:

Drivers Side: 200 200 205
Passengers Side: 195 200 200

These seem high for a cold crank test. Should they be, or are they okay. Range is good, only 10 PSI (factory says 14 is acceptable).

Help, I need to make a purchase and get my car back on the road.
