THOSE WHO ARE FAMILIAR WITH ZC MOTORS

[InfamousZC]

I have a 91 civic with a ZC swap inside. Its been in for almost a year and i ahve a rear main seal leak. and a RPM prob.
1) IS the seal circular or is it two part, cuz a friend said if so i can replace it without removing the transmission.
2) Last week , i was shockingly beat by a focus...as i noticed when i was driving my rpms were loud at only 4 grand. Later that night found that it was redlining at 5000 rpms...and will not go over. IS that an ecu problem? Or is that something else? EVen if the gas is floored wit wont go past 5000, im a lil confused.

its behind the flywheel. youll see it. how can you change a rear main without removing the tranny?

as for the reving...check ur wiring on the ditributor or try a different ecu. was it always like this what kinda ecu do u have? is it a manual one?

It wasnt always liek this i have had the motor in the car for almost a year, just acted liek this last week. i have a pm7 ecu. The ecu reads a code 9...the cylinder sensor...but i dunno if that makes the car not go over 5000 rpm
