I just bought my first Rx-7. It's a 1990 GTU. A lot of smoke comes out from the exhaust. My buddy is a mechanic, and he told me that the apex seal went on the car. Is there any specific way of telling whether it is damaged (meaning I would have to do a rebuild) or not?

 

Alot of people here will suggest a Compression Test.
Do you know how to do that? Check your FSM.

 

Fsm?

 

factory service manual

 

not apex seal, if its blueish smoke its bad oil control rings, rebuild required
white smoke, bad coolant seals, rebuild required
search on both of those and see if thats its

 

where do you guys think i can get one? Is this a good replacement? http://cgi.ebay.com/ebaymotors/1983-...QQcmdZViewItem

 

I missed that part.
Yeh ^ what he says, something like that. Blue smoke or white smoke?
Does it stop smoking?

^ there is a repair manual in here somewhere in pdf format.
look for it. :TYPE: FSM or Factory Service Manual in the search box. and Download it when you find it.

Check out FAQ and the ARCHIVES good infos

*PM'd you the F. S. manual

 

I have another buddy told me it's burning coolant. I know very little about cars, so I kind of have to go on what other people tell me. I'm doing my research on rotaries as much as can though. Cause I really love these cars.
