Does it have a breather that has got blocked??
This happened to my stock 1600 when the breater pipe got blocked. Oil everywhere.
Cleaned it out and all was OK

How old is the motor and what size?

Hi

You could have a crankcase full of fuel or you could have overfilled it.

either too much oil in the engine....

or
You may have been driving in such a way that the oil was pushed out the breather hose... [common]

I have My breather hose down below the engine and body..
and there usually is a drop of oil on the hose...
I don't know how much comes out... lol

Joe

I am assuming you have a type 3 motor.
I have bugger all experience with these.
1835's have a bit of a reputation for blow by with their tinner walled pistons.

The oil level shoundnt be any "higher" just more??
Still should be determined by the dip stick??

You could need more than just the normal breather with a slightly warm motor?
That said - I have a 1916 in a beetle with dual DRLAs and just have the stock breather and no oil spray
You can plumb the breather back into the tops of the carbs and put the system under negative pressure.
That will help a bit

Don't know? it came stuffed at 74,000km.

drank 4-5l of oil in a single 900km trip, ran empty twice and got bearing knock and oil light. the plugs are soaked in oil and my blow by is like an air compressor lol

Still got plenty of power though? some how?

The oil Level should still be the same on the DIPSTICK...
regardless of the extra sumps or oil coolers...

its whats in the sump that counts

Took it for a drive last night after checking the oil (its like 2mm over the max line after running for 2 mins then checking after it settle for 30secs)........now ive stopped freaking out..the blowby seems average,ive re-routed my breather down and it doesnt have any oil coming out of it now..i just wont go hard on that stretch of road as much..

Cheers.

Do you have a breather box for the crank case fumes?
as soon as you go past 1600cc you gotta have one.
