a few days ago, i thought i popped my motor.
i was driving pretty hard and when i let off the gas and pressed the clutch in...
it died...i tried pressing the clutch in and turned it over but it wouldn't start.
i was still going about 20mph so i put it in gear and started it back up that way.
i was able to drive it home by tapping the gas to keep the revs up...
but it felt really rough...i thought for sure i obliterated my apex seals again...
it felt like something mechanically was wrong cause it felt really rough....
once i got it home, it wouldn't start.
fisrt i took off the air filter to spin the turbo(greddy t78) by hand and it feels great.
so next i took off the serpentine and acc belts to see if it was one of those components that might have caused it....nothing..still wont start..
so next i did what everyone else would do, i finally did the compression test...
90,90,90 psi consistent on BOTH rotors, so i'm assuming all my seals are intact...

so does anybody have any other ideas on what i can do to diagnose this?
thanks in advance.

 

A little more background on it....cranks but no start? check for fuel and spark.

 

F*cK!!.. I did another compression test just to verify and NOT GOOD.
90,90,90 on the rear rotor
and 60,60,60 on the front..
got spark and fuel...tell me what you guys think
is it the side seal?
cant be corner seals....can it?
i know it's bad....just tell me what part/s it can be
thanx in advance

 

Just curious, but what mods and how much boost are you running? Really off track, but I've got family in Garrett. Nothing to do there except go to Ft. Wayne, lol.

any ways....i talked to dave and he told me to check my plug, where the omp line used to go(on rotor housing)
checked it....it's good,no leak
so....he said if it's not that than one of the housings are scored.
it totally makes sense.
so i'm in need for another build....
this always sucks...the life of a rotary driver....

 

Do you run premix? sounds like you removed the OMP? Lack of oil lubrication could score up the housing. Also, if for some reason that the injectors were not flowing the same, it could run lean on your front housing.

 

yup..1oz per gallon of fuel
that's what u told me to run steve
it just happend all of a sudden...wouldn't i be able to notice if it happend gradually?
