I put the beat on stands, cleaned all of the oil of with degrease then after a rinse, started the engine.

There are two tiny leaks... one from just above the air conditioner compressor and another from approximately the base of the oil filler hose.

I can hardly see either spot and figure the definately isn't coming out of the oil filter or it's base.

My only fear is it is a sump gasket, but the oil is 'clean' although this proves nothing.

What is above the compressor? Is this where the crankcase breather comes out?

I might as well buy a full set of hoses, and removed the inlet manifold and replace the lot.

I could see the oil pressure sensor well enough to be absolutely certain oil isn't weeping out of it's base, but it isn't 'broke' and certainly works well enough....

Still, I only bought this car to drive whilst I focus on an full engine rebuild on my 406.... grrr....
