I just got a compression test done yesterday. cly 1 240, cyl 2 240, cyl 3 238, cly 4 240. so after 110,000 miles the car still runs great, and I beat the piss out of my car. so rev it up all you want, it can take it as long as you check your oil on a regular basis. hell I can even throw a turbo in the car if I want cause the compression is good.
