hey guys. took this car of mine to a dealership to have a professional to work on it. first thing they did was do a compression test on it. 3 out of the four chambers, cylinders or whatever read about 5.3 compression when the best possible is 7.9 or somthing like that. the 4th chamber read 0(zero) compression. will replacing the rotary seals repair my problem or am i screwed?
