very low compression..need opinions

[redline7]

well I felt like doing a compression test on my 7 bolt seeing that I only had it for like a month. From cyl 1-4 i got 60,140,155,156. I am very familiar with these numbers because I got the same readout from my blown 6 bolt which turned out to be a blown piston in the same cyl 1. Well the car doesnt overheat according to the stock temp. gauge but I did notice coolant at the corner of the head by cyl 4. My dipstick always pops up when driving and my coolant is usually full whenever I check it. The car has a 140k if anyone wants to know.

Sounds like a broken compression ring. Also check for excessive steam in the oil filler cap and see if you can smell radiator fluid in it, if so you could have a blown head gasket. One way I found useful in checking for a blown head gasket is to smell your radiator overflow tank or inside your radiator after it's been running, if you smell fuel then its a head gasket.

head gasket or maybe you droped a valve and scored a piston
