Major oil leak problem please help!!! VW Rabbit diesel

Ok I have an 82 rabbit diesel with an orginal engine. I was driving up to syracuse yesterday and noticed the oil light flickering. So I stopped and looked and found copious amounts of oil flowing out of the vacuum pump that supports the brake booster.

Previously I had a mojor problem with this pump as it would constantly blow the diaphram. In order to combat this problem I rerouted the hose that goes from the engine and the pump. The part that came out of the engine was rerouted to a oil container which allowed for gas to escape without oil leaking out. It was a very complicated apperatus. The suction part of the pump was left with a balloon with holes in it to allow air to come in and out. Any way yesterday I was horrified to witness oil to come pouring out of that balloon. So in attempt to save my car I connected the pump back to the engine despite the fact the brakes will most likely be hard again.

Does anybody know what happened? Did the diaphram simply break? If I put a new diaphram in will it give me my breaks back and make it drivable for a while again? Is my car dead? It still starts fine and drives strong. When I reconnected the pump oil loss also subsided.

Are you saying that this engine has too much pressure in the crankcase resulting in oil coming out of different spots of the engine? Too much pressure could possibly be caused by excess blowby from bad pistons or their rings.

Do you have too much oil in the engine possibly?

Have you been repairing this vacuum pump with kits, or are you purchasing entire vacuum pumps? I have seen a lot of bad diesel vacuum pumps and none were spewing oil out of them.

Did you put any solvents in your motor oil that could be eating diaphragms? If you loosen the oil filler cap while the engine is running, does air rush out?

. I always keep the oil level at the correct level. I have used no engine solvents but there was enough blow by for oil to build up in the vacuum pump and blow the diaphram. I have only repaired it with kits. In what ways does the oil enter the vacuum pump. The engine uses very little oil between changes to the point I usually only have an extra quart handy. I'll have to check about the air coming out of the cap as I've never known to look.

It's OK for air to be buzzing at the oil filler cap but it shouldn't be blowing out. Check the engine's vent hoses for clogging and get a compression check. It sounds like you have a pressure build-up that's popping gaskets.

What Kevin said..........and I have seen clogged up valve cover breathers possibly causing similar problems. While doing V.C. gasket changing I usually flush out the cover with solvent to make sure it is clean. You can check your by trying to blow through it with the oil cap off.

looking at a similar valve cover

formatting link
will see a raised area of the cover where the small vent/breather hose connects to from the intake manifold. Inside of the valve cover at that area is where you find some mesh, which should be the breather. That mesh, over time, can collect more and more debris inside of it until it clogs completely up. Cleaning it out usually requires the cover to be removed and the mesh section soaked in a solvent. Carb. cleaner works for me. Then blown clear with some compressed air. That will take you about 1 hour to do.

6mm allen wrench maybe, 10mm socket wrench setup, 10mm wrench, screwdriver

Of course if you can easily blow through that vent hose with the oil cap removed, your breather should be OK! That will only take you a few minutes. ;-)

OK Have it checked by a good VW shop! I still would not think that a bad head gasket could pressurize the crankcase and the diesel engine still be very powerful. At least I have not seen that symptom, but anything is possible. :-) I have seen the coolant system pressurized or leaking fluids between the head and block or oil in the coolant.

good luck!!

Went to my local VW guy. He cleaned out that filter on the top of the engine. NO MORE BLOWBY. I couldnt be happier

do you mean the breather in the valve cover? 8^)

GREAT!!!
