Engine Mechanical problem
1987 Mazda RX7 V12 Two Wheel Drive Manual 100000 miles
Obviously, this car does not have a V12 - but this site does not have a rotary motor option. It has a 4 port 13B Wankel Rotary as the car is a RX7 Turbo II. Problem is an oil leak from the back of the engine, apparently within the bell housing. I've removed and replaced gaskets and o rings for oil cooler lines and the oil filter housing at the top of the motor. When this didn't stop the leak, I pulled the transmission and replaced rear main seal and the transmission input shaft seal. I used actual factory Mazda parts, not aftermarket. Checked car after driving about 3 miles, and the back of the engine was wet (engine side of flywheel). Besides the rear main seal, where else can oil be leaking from? Has anyone had the rear stationary gear/bearing housing leak? If so, can this be removed with the engine in the car?
