Cylinder Compression Test Results.....need some help

[johnneyinteg]

I'm lookin at buying a 99 Jeep TJ Sport V6 4.0L. I got a full mechanical inspection done this morning with the compression test but I myself am not really sure on if they are good or not. Unfortantly and apparently I could not talk to the mechanic who done them cause they were to busy. Fair enuf. Here they are....if anyone knows about this stuff could ya give me a reply tellin me if these numbers are excellent....good.....hopefully not horrible:

Cylinder 1 - 155 lbs
Cylinder 2 - 155 lbs
Cylinder 3 - 152 lbs
Cylinder 4 - 155 lbs
Cylinder 5 - 155 lbs
Cylinder 6 - 152 lbs

Thanx for anyhelp anyone can give. The only other thing I was conserned about in the mecahnical was a not about the rear brake adjusters being seized. Because of that they are unable to remove the drums??? Is this a serious issue as far as repair costs go. I'm going to have it fixed ASAP however I just wonderin if anyone knew an estimate on what this could cost.

those compression numbers are excellent.
The most important thing about a compression test is if the lowest cylinder is more than 10% lower than the highest one. Your numbers are very consistent. Also, 150 is a nice high number for a stock engine so all cylinders are sealing well

Count on having to get new brake shoes, hardware and likely will need new or machined drums in the back. When the drums are worn, they can get a little grooved and can hang on to the shoes. A mechanic will turn down an adjuster to pull the shoes away from the drums so they can come off. Your mechanic might have to use some force and did not want to damage things to get at the brakes, if the jeep was not yours.

Brakes in that condition is not unusual at all and nothing too major to worry about.

For what its worth,I agree with MagicRat.
