A friend ask me to post the following question about excess oil consumption=
 on this forum to see if anyone has any suggestions.
I know the engine has been professionally rebuilt a few years ago & the com=
pression & leak down tests recently looked "normal". No oil leaks.=20
Thanks,
Gary Hodson

I had a brief conversation with my mechanic the other day and in the next c=
ouple of weeks he will do a complete diagnosis on my Healey to try to ident=
ify why I have had so much oil consumption.  FYI, I just emptied the 6th qu=
art of oil into the engine yesterday =E2=80=93 and that is over 4,000 miles=
.  It is better than before the recent ring job, but nonetheless, is not ac=
ceptable to me.
=20
Mechanic thinks the oil loss might be due to combustion of the oil from the=
 back air cleaner that is plumbed with the valve cover.  He thinks the air =
cleaner I have on it now is somehow creating a vacuum pulling oil from the =
valve cover and injecting it back into the piston and is actually burning t=
he oil off very efficiently.  I still don=E2=80=99t have any signs of leaks=
 beneath the car nor any smoke from the tailpipe.  Quite possibly the curre=
nt Cooper air cleaners are too small and are creating this vacuum.  The Coo=
per air cleaners replaced some other chrome air cleaners the original owner=
 had on the car =E2=80=93 I don=E2=80=99t know if it was original equipment=
.
=20
Will you do me a favor and see if anyone else had a similar issue with oil =
consumption to identify a =E2=80=9Csolution=E2=80=9D that worked for them? =
 Maybe there are other thoughts that we should ask my mechanic to examine a=
s well.

The first check is to remove the oil filler cap on the valve cover with the=
 engine running. Often the worn rocker shaft will show with just that easy =
first check.

If you install the PCV kit on a car that has a worn rocker assy and using l=

Like I said earlier pull the rocker cover you will find that the rebuilder =

I've had a PCV valve installed--the 'Nock Kit'--on my BJ8 for years; maybe =
40K miles or more.  It reduced oil consumption from 1qt/1,500 miles to 1qt/=
3,500 miles or so (highway miles, consumption is a bit more for around-town=
 miles).  There is no downside that I know of; others have reported gunk on=
 the rear intake valves.  I'm contemplating an engine rebuild; will find ou=
t then.   =20
   =20
I think 6qts/4,000 miles is way too much for a freshly rebuilt engine.  You=
r friend could remove the vacuum dashpots--the big dome on the carbs--and c=
heck for oil residue.  If the rear is worse than the front carb it would co=
nfirm oil is getting sucked into the rear carb.  Does he have any leakage a=
round the valve cover?  That would indicate the crankcase is getting pressu=
rized.  Is he dripping a lot of oil?  Is it leaking from the timing cover s=
eal?   =20
