I have a 1987 RX-7 GXL with a 13B rotary. I was speed racing one day and guess what!!?? The engine went caput!! I took it to an RX-7 specialist and he said that coolant seeped out of my spark plugs. I don't know much about rotarys, or engines in general, BUT i know more than most females my age. So anyways, I would appreciate anyone's oppinion. Thanks!!

 

Coolant does not come out of spark plugs . Maybe he saw burned coolant residue on your spark plugs, which told him coolant was being burned?

If the coolant seals that hole the sections of the engine together are shot, then coolant will leak from their passageways into the combustion chamber. This will cause overheating problems and dropping coolant levels. If it's bad enough, it can even seize the engine entirely.

 

sounds like its time for a rebuid

 

pop goes the rotary

 

I don't think you are going to love your car as much anymore when you see the cost of a rebuild.

 

You were "speed racing"? As opposed to the slightly less popular "slow racing"?

At any rate, if you actually have coolant out of the spark plug holes, the engine is seriously dead. You've broken at least two o-rings and/or warped the housings. It's safe to say that very little of that engine will be salvageable in terms is irons and housings. If it has sat for a month or so, it's all basically junk now due to the moisture.

Your best bet is to just find a low cost used replacement engine. Don't bother rebuilding what you have.

 

Rebuild?
