Angry 88 Acura oil in distributor cap still after cam's 1" gasket was replaced

My 1988 acura legend v6 24 valve engine has 2 ounces of oil
still coming into the distributor cap after cleaning out the distributor cap a few days ago, and even after the 1" cam
gasket was replaced by my Acura mechanic. I see oil coming
through the lower of three breathing holes on the circular base
that the distributor cap attaches to.

Will this require removing the head cover to replace possibly
another seal or gasket?

Or is this because of a Positive Vent Case vacuum problem
that is allowing oil to blow into the distributor cap?

I noticed a lot of dark, gooey oil has collected below the
distributor cap on a device that has a vacuum hose attached to it. I also had my repair shop work on stopping oil leaks
that were around the oil pan (only 113,000 miles on engine).

The air filter, spark plugs, wires, coil, ignitor, rotor, and
distributor cap were just replaced last week (plus a $1.92 1"
cam gasket that is on the shaft that projects into the
distributor cap). I also had the oil and oil filter changed and the mechanic said that 20W50 oil was used (I had been using
10W30 oil up to this time).

The rotor and contact points inside the distributor cap are
becoming heavily contaminated with oil and the engine
has just recently been running very rough.

I noticed that the 1/2" long, 1/32" tubule that projects
from the outside of the distributor cap does not have
any vacuum hose attached to it. Should it?

Does the 1988 acura legend engine have a PVC vacuum
system or part that is easily or inexpensively replaced?

I have never, ever heard of such a thing before. I have never even heard a radio caller call this in to any of the car repair radio programs that are on the AM dial on Saturday mornings. Too bad you didn't call one of them up about this, this morning.

Do you have an oil pressure gauge on your vehicle? If so, is it reading normal? If you don't...have you tried to remove the oil fill cap cover and see when the vehicle is running if it is spewing out gases under pressure?

I had a car that developed crankkase pressure so bad with blow-by gases that it forced oil badly into my air cleaner and I was mopping up ounces inside of it! (I had a major engine problem)

On your car, is only the distributor being affected?

I have a hard time it would be a vacuum issue, actually. It rather seems like an excessive pressure (rather than a suction) problem...either with the oiling, itself, or, like me, with exhaust blow-by gases entering the crankcase. Even though you replaced the gasket..if you have excessive blow-by gas getting into the crankcase, almost nothing is going to stop that.

Can't anybody tell you if THAT is going on with your vehicle?

If you do have some sort of normal PCV device, I would definitely make sure that is working, first off.

if you are getting oil inside the dist cap, most likely the dist shaft bushing/seal in base of distributor is worn out. Prob will have to repl distributor assy.

Is a kit available with approp. gaskets for the distrib. assy?

Do you know of a non-manufacturer source for the
distributor assy as well as a diagram showing the
appropriate gaskets to replace when replacing this?

Can crankcase pressure be caused by a clogged oil system?

There is an oil leak underneath the engine; however, I noticed
a dark gooey oily area underneath the oil distrib. assembly
and the distributor cap that has been accumulating gunk
when we bought the used car 18 months ago. This is a family
car for local driving/errands and we did not plan on driving
long distances in the car, as did the previous owner.

The original spark plugs were just replaced (113k miles)
last week and were not showing any oil leak problem.
The air filter was dirty and also replaced as was the
2nd coil (had shorted out due to the 2-3 ounces of
oil that had filled the distributor cap). The ignitor had
also been replaced two weeks ago after the car died in
the road and would not restart.

The radiator coolant is clean (was flushed when we bought
the car), but the coolant reservoir was empty two weeks
ago. I have not seen any dripping other than oil on our
driveway where we park the car.

The car accelerates and engine runs smoothly for
3 to 5 days until the oil builds up in the distributor cap.

Do you have crankcase pressure or don't you?! You have to determine this the first thing to know if blowby is your problem. Remove your oil cap, with the engine running, and see if clouds of gas is coming out. If not, it's probably just the distributor seal. You could remove the distributor (if you know how to do this and get it reinstalled in the correct orientation again!) and perhaps take it to an auto parts store that has an auto machine shop there, and maybe they could replace any appropriate seals. Or just get another one at a junk yard.

check your local phone book for import part specialist(NOT AUTO ZONE or such) I'm near DC, we have a co called Olympus here that sells new aftermarket distributors for prices comparable to a reman unit, but I can't remember the manufacturer name. as dave said, you should probably replace the PCV valve, but I dont think blow-by would blow a dist shaft seal
