Need some VW help

[ASD]

Yeah I know its not a Porsche...apologies....its a 1973 VW Thing type 181.

So I have an oil leak ,,ha no surprise...but the oil comes out of the dipstick. Its an 1835 engine if that matters.
Has a Weber carb, chrome air cleaner and an EMPI oil fill tube with a breather attached.

I think the breather is the problem and want suggestions on how to improve it. I can run a tube from the present breather to the carb. Or replace the breather with a box type.
Or change the fill tube to a Porsche type with a breather.
The valve covers do not have breather tubes attached or holes for them.

I appreciate ideas. Some recommended breathers are also panned by others.
I use the SAMBA mainly for advice ..on the Vdub.

Is the oil coming out of the dipstick or breather. Either way, sounds like a lot of blow-by, which 92mm cylinders are famous for.
If oil is coming out of the dip stick, you have an awful lot of pressure in your crankcase, because the dip stick tube extends into the case past the oil fill line. The pressure is pushing the oil up and out of the tube. Look for blockage in whatever breather you have, because any breather should relive enough pressure to keep oil from coming out of the dip stick.
Last resort, pull the motor and check the cylinders and pistons and rings. If you can have your cylinders honed on a good Sunnen machine, you should be able to see if there are drop out areas on any of the cylinders.

Couple of checks prior to pulling the motor. You can pull the dipstick tube and try and seal it at the block. Clamps at the breather and using a puke box that also connects to the carb intake is what I have used.

Are you sure the breather is not blocked somehow? Show a pic of your motor.

Is there air coming out of the breather? How much?

Is the motor overfilled with oil?

This is my 2110cc T1. My only breather is the stock down tube which is plugged at the top and open at the bottom. I have no problem with oil consumption or leakage, except the drip or two after shutoff.

If you're wanting some other advice, I'd maybe give Mike Speer a call (one of our parts specialists). He's somewhat familiar with older VW's. He has a pretty sweet old VW Beetle. (Pelican Parts - Contact Us). Got any pictures? Would love to see it. Hope you get this figured out.

VW Vortex was always full of good advice back when I had my MK1

Check your oil level make sure its not overfilled, then but the vented valve covers on, vent them to the breather box. Should be done anyways.

My 2074 (Mahle 92B's, Berg 78mm counterweighted stroker with 912 rods, 40X35 heads and 44MM Weber IDF's) has only the stock VW breather and doesn't have any problems pushing oil out. I use a late model (large) fan, stock pulley and a short fanbelt to turn the fan a little faster than stock for extra cooling. It has a factory 36HP fan shroud and a Porsche 912 oil cooler. CR is about 8:1, on the conservative side.
The bottom line here is that the stock VW heads simply do not have the mass to cool a high compression motor, especially when you push the engine size up past 1600cc.
Take this motor apart and measure deck height and combustion chamber size and figure what your real compression ratio is. If it is over 8:1, take steps to lower it to possibly 7.5:1. I think that is what Gene Berg recommended many years ago. Also take some time to fit all of the stock tin on the motor, making sure there are no air leaks, and find a factory Dog House fan shroud and oil cooler.
