An oil leak caused by
worn o-rings on the oil filter pedestal can easily be mistaken for oil that was
accidently spilled from an oil filter replacement job.
This is a very
important leak to check for, since continued leaking of oil from this problem
area can cause catastrophic consequences later down the road! The leaking
oil drips onto a coolant heater hose located directly below the oil filter
pedestal. Oil soaking into a rubber heater hose will cause the rubber hose
to burst. If this hose bursts while driving, you will lose a significant
amount of coolant, which leads to overheating of the engine. If you do not
immediately shut the engine off, you can destroy the engine in very short time -
rotary engines do not tolerate overhating!
- The oil filter pedestal is secured by two 10mm nuts underneath
the pedestal itself.
The front 10mm nut is pretty easy to access, but the rear 10mm nut is a pain!
- Once you remove the oil filter pedestal, you'll see the two rubber o-rings
in the grooves.
Replace with new rubber o-rings.
- When you reinstall the o-rings, coat them with some motor oil.
