    Default Compression Test Results? Is this good?

    I have a hatch with a zc sohc vtec turbo'd and i was doing a comp check to see if it was alright. I have had it turbo'd for about a year and it was turbo'd before so i wanted to see if the motor was OK. I first did it with 6 times over with no throttle and then 6 times over with full throttle. The car is leaking some oil and overheats when im on the highway so im trying to narrow down the problem.

    No Throttle:187, 182, 180, 181
    Full Throttle:190, 191, 190, 191

    I just wanna know if these results are good. From what ive been searching they seem to be great which i would not think it would be due to being turbo'd for so long. Thanks in advance for the advice.

    Man you should see my compression!!!!! Big difference between imports and domestics. But it is amazing on how much power you guys make with those small engines. And then you save gas. I have to buy a whole other car just to keep my fuel hungry beast. Not to mention I have to fill up with high octane every time i smell a gas station.

    I really like it cause i can run low 14's in the 1/4 and still get 35 miles per gallon.

    Having your engine turbo'd, if you're not pushing the limits too far, and you aren't running it like a racecar, will not cause your engine to undergo the kind of super-excessive wear that would really ruin your compression. What it will do, is if you're not careful with your oil changes, it can sludge up the oil and cause a lot of wear of metal on metal areas.
