What is the correct air cleaner for the 4 cyl engine? Pictures seem to show a variety. Thx, tomc5 Also the car I bought was supposed to have had the engine re-built, but that was 7-8 yrs ago. I get from 105-115 compression, which seems ok. Does it make sense to replace all of the engine gaskets w/ the eng off the frame? The eng seems to run fine. Thx again
