If you install the PCV kit on a car that has a worn rocker assy and =
using lots of oil the PCV kit will make it worse.
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 and causing your problem.
The other way to check is just fell the bottom of the rear filter it =
will be soaked with oil.
One test you can do is remove the vent hose to the rear filter and see =
if the problem goes away.
The PCV kit will help stop oil loss due to seal leaks not a worn our =
rocker assy.

Subject: Re: [Healeys] excess oil consumption
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 out then.
I think 6qts/4,000 miles is way too much for a freshly rebuilt engine. =
Your friend could remove the vacuum dashpots--the big dome on the =
carbs--and check for oil residue. If the rear is worse than the front =
carb it would confirm oil is getting sucked into the rear carb. Does he =
have any leakage around the valve cover? That would indicate the =
crankcase is getting pressurized. Is he dripping a lot of oil? Is it =
leaking from the timing cover seal?

I had a brief conversation with my mechanic the other day and in =

emptied the 6th quart of oil into the engine yesterday =96 and that is =
over 4,000 miles. It is better than before the recent ring job, but =
nonetheless, is not acceptable to me.
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 the oil off very efficiently. I still don=92t =
have any signs of leaks beneath the car nor any smoke from the tailpipe. =
Quite possibly the current Cooper air cleaners are too small and are =
creating this vacuum. The Cooper air cleaners replaced some other =
chrome air cleaners the original owner had on the car =96 I don=92t know =
if it was original equipment.
Will you do me a favor and see if anyone else had a similar issue =
with oil consumption to identify a =93solution=94 that worked for them? =
Maybe there are other thoughts that we should ask my mechanic to examine =
as well.
