I know VW's leak oil, but not this much? (Solved!!)

[VolkDubz]

I have a 74st bug I've been working on and I started to get oil leaking nonstop from which looks like behind the crank pulley. It will drip about one drop every second when the engine is running. Now I'm not that engine enclined so the only things that I have done to the whole engine compartment is rebuild the carb,replace stock crank pulley with degree pulley. Does anyone have any idea what this could be? I took a couple pictures of the engine to give everyone an idea of what I have. (Note: front engine tins/exhaust tubes have been removed for pictures)

i bet your cheapie degree pully is not sealing right. put the stock one back on and see if it still leaks.

hooking the crankcase breather up correctly would be a good start
the hose coming off the oil filler needs to go to the port on the aircleaner u can see behind the choke in the middle pic

ur bug obviously has one of those stupid emissions charcoal canisters under the right guard
if not then im praying thats not the other of the breather hose connected to the fan housing cos if it is then its no wonder the case is blowing out around the pulley cos it would be pressurising the case

thos pancake air filters really do suck in pretty much every respect
unless u got it for looks ur car will be alot happy with a stock filter

Mine has that vent hose from the oil filler going directly to a fitting on the underside of the aftermarket(looks about the same as yours) air cleaner. The way mine is would put negative pressure on the crankcase, the way the pictures show yours is, would put positive pressure on the cranckcase and would cause a lot of oil leakage.

I have my aircleaner fitting pluged and the hose from the oil filler venting down under the engine. Does it have to be hooked up? Also on your picture why is the vacuum hose thats hooked up to the manifold under the carburetor going to the left side of the carburetor? On my VW it goes to the vacuum advance on the dizzy, but then mine is a 68.

If there are no grooves on that replacement pulley and it is completly smooth, than thats a pulley for a sand seal. Put the stock pulley back on, or get a quality replacement one with the grooves.

i have that same fuel pump but my hoses are hooked diifer,the top goes to fuel tank bottom goes to carb,my engine still runs,does it matter,thanks

As buggin74 said, the hose from the oil filler goes to the air filter. You said you have it connected to the canister, disconnect it because you are pressurizing the engine case and forcing the oil out around your pulley. If you stop blowing air into the engine, you should only leak what the rest of us do!

A sand seal with correct pully keeps sand out of the case. The grooves like on your stock one help pull oil back in to the case. A sand seal requires a smooth surface on the pully,a grooved pully would tear up the seal.

Okay everyone thanks for the help, I did have the wrong crank pulley. I went out today and bought a nice alum/degree pulley and center bolt with a center tap that you can use a ratchet on to turn over your engine. Now my other question on this topic was about the tube going from the oil filler out to the canister. I pulled nearly everything off my car that had to do with emissions except for that box, if I remove it what can I do with the hose coming from the doghouse and also should I still route the hose from the filler neck to the bottom of the filter?

You should just route the hose from the filler to the air cleaner(this will induce negative pressure on the crankcase) and plug off the blower housing fitting. This will also eliminate the cannister. DITTO on those fuel lines, you don't want them to come loose and spray fuel on a running engine.

And cap those fan housing outlets, and put the rear breast plate tin back in.
That engine has to be overheating like a mother.

AND, VW's should not leak oil. None of mine do.

Cap the fan outlets, with heater boxes in place? No... buy some of that corrugated air hose, run it from each fan shroud outlet thru the rear breastplate and into the top of the heater boxes- you can see the round hole in the last 2 photos. HB needs supply of air to cool them off inside even if you have the heater lever "off". If you cap those outlets, you should remove the HB and use "J"-tubes.

So when you say "solved", was the new pulley effective to stop the leak?
