anyone had a compression problem with their dodge?
My 2000 Ram Van / 3.9 liter 6 cyl has a loss of compression on its third cylinder.
My mechanic though at first it was a valve problem...but when he took the heads off ( which I went ahead and had the rebuilt while they were off) there was nothing wrong...
cam has been checked...
lifters checked...

he put it back together...ran fine for its first test drive...on the second test drive....loss compression again...

 

Cracked pistonring.
