Default Turbo Oil Leak

Now that I have 2 turbocharged 2005 PTs in my driveway, I need to look a little closer at the source of oil leaks on the backside of the engine.

On the Ltd car, I have replaced the sending unit and valve cover gasket. I've not yet touched - but have poked around - the recently acquired GT.

It seems, however, the oil leak might be the same source on both cars, and may be related to the turbo oil return line. The rubber portion of the oil return on both cars seems dubious.

Am I headed in the right direction?

I think I got 'em.

While the rubber return hoses are soft, they weren't really contributors to the problem.

The GT had a leaky oil pressure sending unit. I'd replace that a few years ago and it was, once again, pushing oil through the unit.

The Ltd seems to have been a poor seal under the front camshaft saddle. I had done the valve cover gasket when I bought the car last year, but went no farther at that time because the original seal was very tired. This time I pulled that saddle and it was metal-to-metal. Whoever did the head work for the previous owner may have spready the goop too thin, or not at all.
