Ron,
I noticed that you think that a comp test or
a leak down test will reveal all. Those tests will
not -repeat will not - tell you the condition of
the oil control rings , those tests will give you
a good indication of the condition of the comp
rings .
Example- in the last ten years I have had 4 jobs
come in the shop , all diesel, with very good
comp but using large quantities of oil. 2 were IH
industrial ,they got up to 3 quarts/hr, 1 was cont
2 qts/hr and 1 was 6.9 in ford pickup , 5 qts/225
miles.Remember all with good comp. The 2 IH and
the cont all had 2 oil rings, upper one was 3
piece and had a scraper ring below the pin bore.
Those were engineering problem,cannot use 3 piece
ring above scraper ring , use one piece cast oil
ring above or use 3 piece without scraper ring.
The 6.9 had the rails of the oil ring wedged between
the expander and the side of the ring groove so
that it could not touch the cyl wall.
Have also the other extreme that had more vapor
coming out of the crankcase vent than out of the
exaust pipe and had very low comp but use almost
no oil .

The last time we had a discussion you posted
some smart alec responses and signed buick and
deeres handle to them , don"t think you should
do it again . The madam pulled those posts and
because of them and the complaints filed with
them , I think is why she put password protection
on the names .
I have some other bones to pick , but I will
wait untill the time is ripe for them .
have a good day .

george
