so i have a 88 rx7 vert that has 177,801 miles on the engine. So just curious if i should be worried about the apex seals going out soon? ive heard that they commonly go out around 160,000 miles. Engine still runs great and i have had no problems engine wise. i am the fourth owner of this car and the previous owner mostly used this car as a weekend car, but this is my daily driver.
any help would be appreciated
thank you

 

it really depends on the abuse that the car has seen, but i would say that even in the best of cases you should only expect about 250k miles out of the stock 3 piece seals with a perfect scenario.

 

awesome thnx for the help

 

200k+ if taken care of all its life.
Best way to check to see if you need new seals/rebuild is to do a compression test.
