MODESTO,
California
I have a 99 GSX with 60k miles.. It has some mild mods.. HMI EVO 16g turbo, Had a blown head gasket when i bought the car, had the head resurfaced and installed a Felpro head gasket and torqued to specs, put a new timing belt and water pump..... After the repair we did a compression test and it had 170 psi on all cyls.. I have drove the car as a daily driver for about a year now, i dont race the car pretty much baby it... Any way last night i went out to start the car and when i turned the motor over to start it, it would not start it sounded like the car had no compression and that maybe the timing belt broke or came off, all i could think about was bent valves.. I took off the timing cover on top of the motor and found that the timing belt was still on and tight i thought for sure that it had came off.. Then i went and did a compression check on all cyls and found out bad news.. The compression readings were 55psi, 40psi, 40psi, 70psi... The readings were steady at that pressure and didnt seem to fall...
I do not understand what has happened here.. The car was running perfect when i parked it in that spot a few days ago, you would think i would have noticed the car running poor as the compression was slowly getting low.. It went from running great with strong boost, to parking it for a few days to a dead motor. How does this happen? Im stumped.. I thought maybe it was a lack of oil issue that chowed the rings, or a head gasket leak around a cyl or 2 but not all. Lucky i have a spare car to drive to work, but this sucks.. what do you think has happened here.. I really dont want to tear this 60k motor down...
