compression test results
 

Well did the compression tests on the car I am planning on buying. I only got to do 2 outta the 4 plugs.... the top two. Bracket was in the way for the other one on the bottom front, and didn't really have time for the bottom back one..... well the numbers were 80, and 110. Are these good numbers?

well a few ? was this with a MAZDA tester or a piston tester? the 80 is outa spec but should still go for a while. but theres a HUGE gap you want no more tha 10% diffrance. and the true way to do a test is on the top (T) plugs with a warm (chock has turned off) motor you kill the fuel and ing and hold the foot feed to the floor while spinning the motor over. I see "normal" motors doing anywere from 89.3 psi -113.1 psi, but i have seen cars with 75ish psi run for well over 2 years.
and i use a mazda tester. i acc have a test to do thursday am fora posable new owner of a 80 limited
