How about a quart per fillup?

And I totally disagree that these engines need to use oil. My engine =
was rebuilt by an excellent mechanic, and it uses practically no oil. =20

I almost never have to add oil. And we drive it hard. =20

Subject: [TR] TR6 issue
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.
=20
All pollution stuff is gone.
=20
Compression across all 6 cylinders is within a couple PSI
=20
Leakdown test was a small % on all cylinders
=20
Engine uses a lot of oil and there is a blue puff when he accelerates or =
engine brakes
=20
We think its likely the valve guides are leaking.
=20
What do you think?
