I have a friend who has a 74 TR6.  Recent rebuild of the engine both top and
bottom.  We are a little suspicious of the machine shop that did the head.
The bottom end was done a year later by a different machinist.

 

All pollution stuff is gone.

 

Compression across all 6 cylinders is within a couple PSI

 

Leakdown test was a small % on all cylinders

 

Engine uses a lot of oil and there is a blue puff when he accelerates or
engine brakes

 

We think its likely the valve guides are leaking.

 

What do you think?
