You have to have an engine rebuild which costs from $2500 to $4000 depending on other internals that needs replacing and labour of the shop.
Your apex seals might be bad, your engine may need a rebuild!
Bad Apex seal
if you have a bad apex seal you can replace the apex seals and side seals depending upon the condition of the engine, if the housing or side wall is worn or scraped badly than you will need new housings and possibly side walls. but your motor may run depending on how badly worn the apex seal is.
It is 5.8 Liters for an FC Rx7.
you lose power and the engine dies... you lose power and the engine dies... Or you go no where very quickly! (for pictures of blown seals go to http://www.noveights.com/id93.html )
I had the exact same problem. I own a 1984 Mazda RX-7 GSL-SE and what i did was bought a new starter. A new starter actually will start a flooded RX-7. But if you dont want a new starter then push the car and the car will start. now the rough start is related with the seals and oil. the oil is low or bad and/or you need new seals.
what type of oil can i use for my Mazda rx7
No. Oil cooled.
royal purple
20-50w non synthetic
rebuild or replace.....you have a serious issue there
ha ha! you need apex seals. Very common with rotary's.
