For what it is worth, I have had numerous times without leaks in my '88 WBX. Also I disagree with the statement about 86-92 Porsches. I have an '88 and the only time it has ever leaked has been when a seal or oil line has been faulty. At one point it was smoking on startup that one mechanic explained away as leaky valve guides, so I lived with it. The last time I took it in, a different mechanic noticed a number of leaking seals and hoses, which were replaced and now no smoking at all. A good lesson to not always believe what the mechanic tells you.   I would say it is all about the condition of the parts and how well maintained the engine is - and how clean the engine compartment is kept. But you can get a dripless engine if you work at it.   Todd '88 Westy

Ken,   I'm going to just dive in and get right to it and avoid the protracted history and methodology.  Even the most expensive Porsches with flat motors "leak".  Trust me, the materials and prep those older 911 motors (esp 86-92) are top notch and they *still* drip.  What happens is the hot oil on shutdown is, as part of the lubrication of the valve gear, trapped in the heads.  One if not more exhaust valves will be in an open position.  That hot thin oil seeps its way past the valve guides, drips into the exhaust, collects, and eventually spills out.  Nature of the beast even when new(er).  Granted, certainly much much less when new/rebuilt due to tighter clearances, air cooled motors need a lot more clearance for thermal expansion.  Add some age, worn out seals, and certainly, it will find a way out of the heads and gaps around all the junctions of metal parts. Only exacerbated by a really hard drive.  Trust me, I've nailed a few early morning "runs" at sub-light speed in a 911 and on engine shutdown those things creek and pop like mad as they cool.  Water cooled heads or not, VW or Porsche, different beast, same story.   For me, it's a minor trade off for the most inherently balanced car engine design.  A drip pan is a required "tool" for a Porsche tech. LOL.
