If I was to do a compression test on my motor ,what number should i be looking for?My car is a 6 bolt 1g eclipse awd.

125 to 163 I believe on a 1G 6 Bolt. Hang tight and I'll double check.

Correction 121 to 165.

I've also heard that there shouldn't be more than 10% variance between any two cylinders. It doesn't mention that in the FAQ though that I saw.

Was the car warmed up before doing the compression test?

Follow the procedure I gave you above to a T and that will give you the correct compression readings.

A cold engine will give low readings. A warm engine will give correct readings (metal (rings) expands when warm).

Like I said. Follow that procedure to the letter and see what you have.
