"New" 1999 C4 shake-down - hints?

Update FWIW...
So I picked up the car from the dealer servicing--relatively clean bill of health. Oil change and brake fluid flush. $350. Ran the VIN and found a gas cap recall. Mechanic couldn't believe how clean it was--which of course made me feel reasonably well that I made a decent buy. Of course the dealer did try to get me to do the RMS which they said was "seeping." However, they seemed to back off on the matter when I said that I had been watching the garage floor with a critical eye and hadn't noticed a single drop.
This weekend the snow tires go on :-)
I also hope to test the Porsche roof rack that I bought off the PCA classifieds; it's all coming together.....

Yep a car sitting around not going through heat cycles with oils flowing will have gaskets and seals leakings more than usual. Even seen some hard rubbers turn to sponge from sitting around. Do a gentle break in to get the seals to rejuvinate and watch for leaks in case one gives out from being too soft. Or just relace if thats the route you prefer.
One of the bad things of cars sitting is oil sediments having a sit around and tuning into hardened garbage on metal surfaces. It's like letting a kid make food on the counter and not cleaning up the mess and letting it dry hard. Just running cleaner over it wont clean things up after that. Of course an engine oil path is sort of like a hot solvent tank bath so things might clean up well.
After things get settled and you are comfortable try crusing along on a long stretch of road with a high speed limit. Here is the thing I would do on that stretch of road. Get into a gear where you can exercise the rpms back and forth below and above the variocam operation range. Go back and forth from around 2.5k and 4k rpms to make sure the piston section that operates the cams is being functioned and hopefully getting cleaned up. I hope the material on the cam adjusters isn't prone to rotting from sitting around not being used. Thats one reason watching the oil removed from the car will be helpful to see if that sort of stuff is falling apart.
You have found a great car to keep for a long time. The 99 might be a super collector one of these day. I've tried having friends drive my car while I sit there for the ride. I know many guys would love to own a prorsche so I try to give them the thrills needed. It seems anybody I let drive the car is always playing like they are rolling the space shuttle back and forth along the launch pad. The car will launch very nicely and radically at times when in the higher revs. Just make sure you have it well broken in with the seals all tight and have some fun down the road from time to time.
Fantastic car you have. Good luck the first time you get pulled over by the police
Oh yah, nice dog. Mans best friend for sure.

If I were you...and some may not agree with this, but change the fluids, and give it a nice 50 mile break in, with varying RPMS. Than wind that motor out and put it through its paces. I would suggest a IMS bearing, your cars milage and year is a prime canidate for failure according to the rennlist rumor mill.
