Avanti excessive oil leakage
Chick
oil out of the passenger side engine compartment? It's litterally
spraying the entire lower engine including the passenger side right
front tire and wheel with oil. It doesn't appear to be leaking
anywhere so much, just spraying oil when driven. It appears to be
coming out of the dipstick tube believe it or not. I used about a
half a quart of oil in 85 miles today driving it around in a
combination of city and highway driving. This is a just acquired car
with 78,000 original miles that had been sitting alot of the time
before it was acquired. Any suggestions by anyone? Any help or ideas
or where to look would be greatly appreciated before I really tear
into it. I'm wondering if something is plugged up, I'm soaking the
oil filler caps in karosene and letting them sit for the night at
present, not sure if that could cause the problem or not.
Thanks, Everett

No blowby, and the compression is good. I'm wondering about the oil
filler caps because I have them soaking right now (they look like
they've never been cleaned} and I'll check and blow them out in the
morning. They look like they have never been cleaned and I'm
wondering if that could possibly be the problem. Appears like
something may be plugged up or something. Oil pressure is good, maybe
a little too high at 55 lbs. at 40 mph and 35 to 40 lbs. at idle fully
warmed up at 600 rpm. Very original car never been restored and
strange for this problem. Just wondering if anyone has any idea where
to look first before we get into serious stuff. I don't want to get
into any more than I have to if possible. Thanks, I'll check the
filler caps and blow them out in the morning and report back. Thanks
for the input.

is blocked. Years ago a friend had a 63 station wagon with an R2 and one
day it started blowing oil all over everything. Turned out the road
draft tube was plugged with mud.

1) Serviced the pressure relief valve/
2) Removed the valve covers and cleaned the oil return passage?

...and you might add bad PCV valve. Sorta sounds like a ventilation
problem. Another possibility is poorly seated oil filter..

If it's "spraying" oil under pressure, sounds like a ventilation problem
to me or maybe the oil filter is seated incorrectly since it is
involving the right side of the engine.
While the oil filler caps are important on Studebakers, the R series
engines have another vent direct from the oil pan to the air cleaner so
that minimizes this issue.
OTOH, the low original mileage may be an indicator of sludge and poor
return of oil to the pan.
Keep us posted,

Thanks for the input, I'll check all areas mentioned here. I'm
wondering if the high oil pressure could be the problem as well as a
ventilation problem. The oil pressure relief valve is hard to get at
on this car due to the supercharger. I've got to read the shop manual
and find out how to remove that supercharger, that spring looks very
intimidating. Does anyone know if there's a PCV on the R2 engines??
I appreciate all the input. Thanks Everett (Chick) Nauha

Check your rubber oil pressure hose at the back top right hand side
(passenger side) of engine.

I had a Lark that I overhauled the engine in that routinely ran at 60
psi (or more) at highway speeds and idled at 40 psi. Never leaked a
drop. The only way that I know of for oil to "spray" out is because of
blocked ventilation or a compromise in the oiling system. As Jeff
pointed out, plugged oil return passages in the head(s) would reduce the
engine's ability to ventilate.
Since the Avanti uses two means to ventilate the crankcase, this
possibility is reduced but not eliminated. That leaves the oil filter
an/or bracket assembly. That would fit in with problems of oil "all
over" the lower right hand side of the engine and adjacent areas. Of
course it could also be some sort of weird damage to a head gasket etc.
but not likely.
Just my 2� worth...

Good point as these things become brittle and can break easily after all
these years. However, the original poster complained of excess oil at
lower levels for the engine so I discounted this possibility.

I did change the oil and filter, the original filter did have a puddle
oil on the top of it and I suspected that was the culprit. After
changing the oil and filter there is no longer a puddle on top of the
oil filter. I can see the top of the oil filter with a flashlight,
and I noticed that when I first got the car and thought that was it.
After changing the oil and filter I thought I was all set because
there was no longer any oil on top of it. But after a day of driving
in all kinds of conditions, side roads and highway it was still
spraying oil from what looks like the dipstick tube area because I was
thinking it could push the oil up and then with the dipstick act as an
umbrella and soak everything on that side of the car.. The right
front passenger side tire is soaked with oil on the inside, and I was
wondering if possibly the front seal or timing cover could be leaking
and maybe the fan could be spraying the oil leakage if it was
servere?? I'm kind of stumped and I'll be checking things one at a
time and post what I find. Now the weather has turned with snow, so
if the roads are salty I'll have to wait for another good day. I
really appreciate all the comments and ideas from you guys. I'm a
former autobodyman and a half fast mechanic as I had to be when I was
younger and I need some help.

the tire, along with everything else on that side. In my case the u-
shaped front cork oil pan gasket had shrunk. This left a void on the
passenger side front corner, about 1/8" square. The oil mileage was
about the same, as you indicated. Once the pan gasket was changed, it
went up to 500 miles per quart. New umbrella seals on the valves
increased it by another 300 miles. Lastly, a new felt seal behind the
vibration damper gave another 100 miles. The rear main seal was OK on
that one.

Interesting, I was talking with a Stude guy I'm sure you know him
everybody does. Dave T. from Maynard Ma. and he mentioned the oil pan
gasket also as well as the front timing cover. When first acquired it
was smoking and we changed the valve seals which cured that. Now I'm
dealing with the leakage and the spraying of oil. This will keep me
busy for the winter and I thank you for your input.
