i finally got around to doing a compression test and the needle on the gauge wasnt hitting anything higher than a uniform 90 psi on both rotors. its supposed to have 3mm seals in it, and from what ive heard those dont seal quite as well.
does this sound about normal? |

What is the mileage on the motor? I wouldn't be too darn happy with 90psi.
|
probably about 40k. you think it would make a difference if it were tested properly with the mazda compression tool?
|
Ok dude, that's low for that mileage, even if it is a turbo. Do you know who rebuilt it or is it a j-sec? Yes it would be more accurate with a mazda tester. How are you testing by the way? Are you just holding down the release button. If so, you will get lower readings. Also try and check it in the leading plug hole not trailing. Finally, don't hold the button down and tell us what the max compression is after 3 pulses.

i tested it with your regular piston setup, i just took out the valve on the spark plug end of the hose. i was testing it from the trailing hole.
i have no idea who rebuilt it |
