coolant in my oil

ok so ive got coolant in my oil. from what ive read thats pretty rare in a rotary but the most common cause is seepage between the housing and one of the plates. so other than a rebuild is there a way to fix or slow this down? or is a rebuild inevitable?

Sweet! Now I have 2 12a paper weights. I guess I'll just keep driving her and stop using the expensive oil until she quits running then I'll yank the engine and tear it down.

If you pull it now there might be good parts to reuse. If you keep driving it no telling what could fail ($$$).

Agreed. Constant water/coolant treatments makes apex seals wear faster, which equals breakage and a more expensive rebuild because you'll need housings and rotors.

Time to learn how to rebuild these engines. It's actually kinda fun, and way easier than a boinger.

Water in oil your will cost you your bearings and possibly your e-shaft if you keep driving it, in addition to seal wear. Left long enough, the seal wear will cost you your rotor housings, too.

If you're just gonna waste NLA parts, could you please switch to Subarus or something?

It's my daily driver and I don't have the money for a rebuild right now. It seems like everytime I fix something it's followed by another issue. I'm actually trying to save up for a TII engine for my other 83.

Better off to go buy yourself a cheap honda beater car. You will just end up doing more damage to that motor.

And this surprises you on a 25+ year old car in what way?

Time to crack open the keg and borrow a car. Watered down oil will progressively destroy anything metal the oil runs through. Sorry but it will get worse. We can answer your rebuild questions

If you continue to run the car as is, you could end up toasting the bearings before your next oil change. To prevent this, oil changes as often as gas fillups will be necessary and even then the engine won't last long.
