3.0 cylinder problem
 
Hi

We have a 77 turbo with a blown cylinder gasket.
The outer "ring" of the cylinder has some problem
What should we do with it? Our machine workshop confused :confused:

hmmm... to me, that looks like it's ready for the bin. Need to find a replacement cylinder.

Head stud failure. The cylinder pressure caused the head to lift and the gasket squeezed out. If the rings are in tact, it probably wasn't caused by detonation.

We have good used cylinders if you are looking for a replacement.

The previous mechanic forgot to connect the wastegate.
18 head stud was broken
