Wankel problems
 

In universal langugae..it's called a rebuild!

Nothing about rebuilding a rotary engine is going to be cheap unfortunately. The seals don't get loose they wear our or break or the apex seal springs collapse etc. I would suggest a compression test if you are unsure of the engine's health.

thanks :(:(:(:(

If the car isn't running well, seek out the opinion of someone familiar with the car first. New owners who know nothing about rotary engines always blame the "seals" or "apex seals" for everything because it's the only part they have ever heard of.

I'm not sure why "nothing about rebuilding a rotary can be cheap".

If the hard parts are in good shape, then it is a gasket and seal kit plus the labour. Assuming labour is free, about $1000 US. I wouldn't say that is cheap, but I wouldn't say that is expensive either.

If the hard parts are within spec and in nice shape then the cost isn't terrible. However, I haven't had a good usable 12A rotor housing in some time. And now that they are NLA the cost of a good non flaking housing is very high. Even the RX-8 housings are expensive at over $700 per housing new. The housings are really the only drawback to rebuilding the engine for a reasonable price. Its hit or miss when you open the engine. I have an RX-8 engine that I'm going to rebuild next and it has 94k. Hoping the housings are nice as the complete rebuild kit is only $1600 form Atkins. Not a bad price.

Wow. Sucks parts are hard to find.

I had bought an fd with a wankel not knowing much about them, engine ended up being blown. I got quotes from 6-10k for a stock rebuild. Decided to do a 2JZ conversion instead.

You what? Well, for us here in the US a 2jz swap is not cheap, i would rebuild the 13b a few time before going to that swap,. I can tell you that i would sell the car before doing that swap. Dont get me wrong 2jz is a great engine, but i love my lilte 13b.
Good luck anyways.
