I put the engine up on a a couple of sawhorses tonight and got ready to drop the oil. I pulled the 21mm plug and.......nothing.......now, the dipstick showed oil, so now Im thinking it must be plugged. So I dropped the circular plate and.....drum roll.........found over and INCH of sludge. A solid little cake of sludge, and inch thick.

With the plate off, I let it trickle thru the screen for about 10 minutes and pulled that down too. I reached up with my pinky finger and flushed out a bunch more sludge. I then poured about half a gallon of gas thru the oil filler to knock more of it loose. Id say there was only about a quart and a half of oil in the engine, and maybe another half quart of sludge.

Heres the interesting part...she show signs of some serious oil leakakage. The best I can tell, its coming from either the head/jug seam or the pushrod tubes. Would a head gasket leak oil on this engine? I REALLY dont want to pull the heads on this engine. After all my exhaust studs snapped, I dont want the same experience with the intake bolts.

Its probably the pushrod tube seals leaking. The sludge is a common thing on an engine with an oil leak. You see some folks think that because it leaks and they are always adding oil there is no need to change it as often. Not smart but it happens. You can replace the pushrod tube and seal without pulling the head. I've seen expandable tubes used to do this. You have to remove the rocker arm, pull the rod and cut or bend the old tube until it can be removed. The new tube with seals is inserted and expanded until tight, the pushrod reinstalled, rocker arm replaced and valves adjusted. You can get the tube here: www2.cip1.com/ProductDetails.asp?ProductCode=C13-4108

Intake bolts are not like exhaust bolts. I have never seen one snap. A little PB Blaster and they should spin off.

Removing the heads is not difficult. There is no head gasket. Stock pushrod tubes (or stainless if you have the $$) are the best, with some quality seals.

To pull the heads you remove the rockers, remove the pushrods (keep them in order) and take the nuts off the barrel studs. Then just rock the heads off. If you think you are having a leak at the base of the barrels (unusual but it happens) you can carefully slide the barrels out without popping the pistons out and you can apply a little gasket sealer to the base of them (after you clean them).

Now forgive my air cooled ignorance, but how does a head seal itself to a jug with no head gasket? Im still learning this design.

A good machine fit? Typical German standards. Ive got 60 year old German crew served weapons that have seen service by Nazis, Russians and Israelis and are still toleranced within .005! One of the reasons why I picked up this project is because Im so fascinated with the VW experience. Ive never understood the allure. The Germans just manufacture things with a different mindset I guess.
