Just got my weber dcd RE setup installed on my 85 GSL. Finally got it to run but there is something that comes out of the oil filler tube breather line. It's kinda brown, smells and feels like gasoline. Everything is fine when it's first stated but if I rev, it spews or when the motor comes up to temperature, I can see a vapor coming out of the hose. If I keep reving it when it's warmed up it bubbles and boils out. And it is VERRRRYYY hot!
Any ideas? Thanks.

Moisture from the crank case.

NCross is correct. If you have an extra vacuum line for your carb you can hook the breather from the oil fill tube up to that vac hookup with a PCV valve and the engine will simply ingest the nastiness thats coming out of there. If you search for "lung mustard" you will see different setups to solve your problem.

I guess changing the oil would help? I'm not for sure how long the car had been sitting.

Might help. Im pretty sure youre the first guy to mention it "Bubbling and boiling out". Most people mention a thick yellow gunk stuck to the top of their oil cap.

if you don't know how long it's been sitting then for sure change the oil :P, and as far as i know just routing it with a vacuum line back to the carb should be fine, some have added a PCV valve and some haven't either way would work i suppose

thats called NACHO CHEESE.. one of my favorites even though its processed.
no need to worry about it, its called condensation

The reason I was worried is it was dumping enough out that it was dripping out of the bottom of the charcol canister, yet to be removed.

Yank out the canister too I have my rats nest out so I just hooked the "out" side back into the carburetor spacer barb. Mine doesn't bubble and boil out though. Maybe a few drops here and there. There may be some excess moisture in your oil. Or it could be low quality oil. Switch to Castrol GTX 20w50 if your not already using it.

BTW, has the car flooded multiple times? This can cause gasoline to mix into your crank case which can be bad if enough of it gets in there. Gasoline isn't a very good motor oil...

Could be coolant in the oil. Would definitly change the oil first though.
