And you'll be able to spot trouble comming, long before it gets serious if you do it regularly.
I am a few miles away from 180K. In December my intake gaskets where replaced. They also did a compression test. The results were 220 in all 4. Does this seam high? I was digging through my receipts last night and found the result of a compression test that was done about 6 years ago that was 185 in all four. What has caused the different from 185 to 220? Could it be the testing equipment? Maybe the technique, or maybe some engine work has been done. I have all the receipts and there are none for any major engine work.
