oil leak, and oil in air filter

[A KIRK]

Right ok I'm after some advice here please, engine is an original vw 1600 Aircooled CT engine with around 105000 miles on it, so bound to die soon

Right I seem to have quite an oil leak 2.5l in 900 miles, the oil seems to be leaking on the top of the engine running down, and dropping on the floor.

Now in my mind the only place it could possibly be on the top of the engine is the breather housing, but I've put a new seal on and used gasket sealant, the seal was a metal plate style.

There is no oil leaking from the oil cooler, distrubitor, or fuel pump.

However after cleaning up the engine today and running it for an hour I can't find any new traces of oil on the top of the engine, so this leads me to wonder could one of the push rod tubes be leaking and pushing the oil up onto the top of the engine?

I also found oil in the air filter, not much but enough to make a mess, are there any common problems causing this, or am I dreaming that its not a sign of a worn bottom end?

Obviously I am aware that for an old vw engine 105000 miles is a lot for an original engine, but I'm not really wanting to replace it yet, unless I can locate a sensible priced 2.0 turn key.

Any advice would be greatly appreciated

thanks

I do not know much about the air cooled engine but would have thought 105 thousand miles not to excessive. My 1.6 diesel leaks oil everywhere but that is due to very worn piston rings causing pressure build up where there should not be.

Not much help but someone will know I am sure.

First job would be a clear out of all the pipework associated with the emission control and engine breather systems. These can cope with a lot of blow by but can be overwhelmed by a badly worn engine especially if the pipework is all sludged up. White sludge is usually caused by running an engine cold which is sometimes due to a duff or missing thermostat. For ring or valve guide seal wear look for blue smoke when you come off the overun. Hope this helps.

Thank you, all breathers/pipes are clear, and have been checked.

I wasn't made aware of any smoke from the exhaust when on overrun, when in convoy last week, but i'll double check with my friend who was behind.
