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=
ots of oil the PCV kit will make it worse. =20
=20
Like I said earlier pull the rocker cover you will find that the rebuilder =
installed the worn out rocker assy. The oil will be squirting way to high a=
nd causing your problem. =20
=20
=20
=20
The other way to check is just fell the bottom of the rear filter it will b=

=20
One test you can do is remove the vent hose to the rear filter and see if t=

The PCV kit will help stop oil loss due to seal leaks not a worn our rocker=

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

6 quarts over 4000mls does not sound to bad for an old design British engin=

Check and clean the crankcase ventilation system first. Check for wear in t=

I know the engine has been professionally rebuilt a few years ago & the com=

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 6 =
th quart 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 acceptable to me. =20
=20
=20
=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
=20
=20
=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=
