The Diagnosis :(

The Diagnosis :(
A few days ago I was carting some people/gear around in my 93 960, we were pulling a lot of grades with a headwind, so the car was running between 3500 and 4500 rpms for several extended amounts of time. The other day I noticed it was leaking a bit of oil, and there was a fair amount that had blown back and "dotted" parts of the underside. I checked the level, and was 1 qt low. (it has been almost 2k since last oil change) Took the car to the mechanic the other day to have it diagnosed, and I was told that that it was leaking oil from the crankcase ventilation system, that all cylinders had around 125 psi, when they should be at about 170, that there was a minor knock which could be due to a partially collapsed piston, and that the leak I was getting was due to blow-by. I love the car and it runs great. Super smooth idle, revving, and gas mileage. It has 165k on it and I am religious with maintenance. Should I be super worried? try to get rid of it asap? or just accept that it has finally been "broken in" and keep taking care of it......maybe dump a can of "restore 6" in it and see what happens? Any input is appreciated -thanks-

RE: The Diagnosis :(
Hoses were all clear, and all the gaskets/seals looked ok, I was just having a lot of blow by. Mechanic said that based on the compression test, the rings were probably worn. It's funny because when I drive the car how I normally drive it (nice and easy) I get hardly any oil leakage, (just a drop or 2 every few days) and whenever I take it on long trips where I am driving at a constant speed for a long time, I have no oil leak out at all. It seems that as long as I don't drive it hard it doesn't leak much at all. Does that make any sense?

That makes sense.......we'll she's running good and strong right now, and so far I have not lost any noticeable amount of oil. So I guess I'll just see what happens. Gotta wait another month or so for it to warm up enough so I can give the vent system a thorough check.
