right now I'm looking for a 2'ed gen rx 7. but i dont know really want to look for, what to ask a dealer, what some problems that commenly happen to second gen's.



Thanks for any help ^.^

 

Just to get the ball rolling here...



Start with a compression check. This is to make sure the motor isn't blown, or how worn it may be.



You don't want to see any smoke in the exhaust. White smoke can mean blown coolant seals, gray smoke can meat blown oil seals.



Take it for a decent drive, and watch for any overheating.

 

Thanks, but how do i check the compression?

 

With a compression gauge. Less than $20 from an auto parts store. You remove a spark plug from the engine. Screw the compression gauge into the spark plug hole. Have some crank the starter (be sure to remove the EGI fuse so the engine doesn't start), hold down the pressure relief valve on the gauge while the engine is turning over, and look for 3 even pulses on the gauge.



Then do the same thing on the other rotor.



This is very basic and easy as far as vehicle maintenance is concerned, so if this sounds like too much, you should just take it to a shop and have them look it over.
