Well my newly acquired e34 m50 has low compression on 4 cylinders!

#1- 100 psi
#2- 130 psi
#3- 150 psi
#4- 150 psi
#5- 210 psi
#6- 210 psi

Quite a difference... surprisingly the engine runs smooth and decently smooth!

The engine smokes a little on acceleration.

Granted it has 258k miles! I am the third owner and the second guy had the car 15 years and has a stack of records.

I will be looking for a 2.8 soon, but have any of you experienced such low compression numbers on an m50?
