I recently got a 1989 Maxada Rx-7 (no turbo) with an overheating problem. The engine as about 150,000 miles on it. It has had new coolant hoses, radiator, thermostat, etc. It runs a little rough and slowly oveheats within 10-15 minutes, especaily at freeway speeds. The temp gauge maxed out once (bad sign I hear) - but it did not boil over. A mechanic said there were exhaust gases in the coolant, but he also said it may be blown head gasket which I recently learned rotary motors do not have...

Basically, I think the car needs a new engine block due to an internal coolant leak. Before I chased one down, I wanted to make sure there is not an easier fix I should be considering for this problem. I'm not very familiar with rotary motors, but learning quickly. Thanks.

To me it sounds like your motor gone and kicked the bucket with that many issues, I would vote on paying the 24-3400 for a new block.

REBUILD

Yeah, that's what I was saying.

Beofre you go nd blow a hole bunch of money on a new motor try to insta-fix trick. Some of the block sealer junk, i have heared many people extend the life of there rotaries with this junk. :P

Then when it blows, give me a shout.

but in the end, thats like putting a band aid on a bullet wound

I don't even know if I would bother doing that. I mean, what is the point, if it goes after that or if it goes before then. If he bebuilds then the motor is reliable, or should be. Compared to Insta-junk.
