#1. Sounds like the oil leak might be coming from the back of the cylinder head? Not sure, I've not worked on the later 2.5L 924S/944 motors.

#2. Change the fluid to Redline MTL or the like. See if that helps (can't hurt) then look at the linkage as it tends to wear out over time, should be the same as the 944, so there are some neat parts available to rehab it and even make it a little better.

In addition to the above...

For #3, I would also highly recommend Paragon Products, not only for brakes, but for many other suspension upgrades as well. If you call Paragon, ask for Don Weaver, and tell him Dan Beckett referred you.

For #4, as an alternative to OEM, I was turned on to the Kingsborne wiresets by 924RACR (Vaughan Scott), which are as good if not better than OEM spec. I can source Bosche, NGK or Kingsborne wires FWIW.

For the hatch struts, be aware that the 931/924S hatch uses different struts than the 944. The latter has a larger, heavier spoiler, so the struts are stiffer. There is some speculation that the stiffer 944 struts may contribute to hatch frame separation on the earlier hatches, so you may want to be cautious when ordering the struts. The correct 931/924S part numbers are 477.827.349.D & 477.827.348.F.

For any of the OEM replacement items, I can usually source those parts at prices that are very competitive with the big catalog resellers. While I don't have the ability to provide a convenient online pricing tool like the big resellers, I do appreciate the opportunity to quote, so if this is of interest, drop me a PM.

Just to clarify, on the shifter issue, it's not so much the shift lever in the cabin, but rather the linkage at the rear of the car on the top side of the gearbox that you need to be taking a look at. It's conceivable that it's gummed up or corroded in such a way as to impede shifting.

Shifting. . .pull back the boot in the passenger compartment, and check for a plastic socket at the base of the shift lever. These are made of BrittelsheiB, and often crumble/vanish. While you are in there, look for play between the pin coming off the shift lever and the rod that goes to the rear of the car. It should be a snug fit, but the pin coming off the shift lever is susceptible to wear. If this is the case, you can get a new shift lever (salvage), or take yours to a machinist and have the pin replaced. Also raise the rear of the car and check where the shift rod connects to the gear selector shaft that comes out of the transmission. This joint is fixed with a conical screw that should be safety wired. If there is no safety wire, make sure it is tight, and safety wire it. +1 on changing to a good quality gear oil.

Oil leak. . .cam tower gasket, valve cover gasket are both leakers. Thoroughly spray the area with brake cleaner and get it clean to help you isolate the leak. A GENTLE and EVEN retorque of the valve cover often gets this leak to stop. If it is the cam tower, then off she comes, and you get to learn to do a belt service on a 2.5.

Good luck!

It's probably a 15 minute job, maybe 30 if you have alot of clean-up to do.

You can get the gasket from Pelican Parts, or if you have a dealer close by, you could get it quicker. It's only like a $1 part, so the dealer can't rip you off too much. Some people have made their own out of a roll of cork gasket material, but I've never been in that much of a hurry.

As for sealants, everyone has their preferences, but I've done four of them dry, and I've never had one leak. Just make sure you torque the bolts to the proper value (6 or 8 ft/lb).

Here's a picture I came across of the location of the cover. It's just behind the "P" on the cam tower.

Paragon Parts is the best - they have always supplied me with top quality OEM parts, and original Porsche branded items.

For heavy things like rotors and pads, I have discovered this place:

www.autopartswarehouse.com

has really good prices on common parts for the 924S/944.

(I bought a Sachs clutch kit here for my 986S - it was almost $200 less than what most places were asking)

For less common specialty parts, stick to Paragon or Pelican.

Don't forget that Clark's Garage (www.clarks-garage.com) is your best friend when working on a 924S/944.

Go to that website and click on the Shop Manual link - you'll find 99% of what you need to know about fixing up your 924S.

I have a spare linkage if you need it.

You might need to drop the tranny to get at it, but I think you can replace it without dropping it. Removing the rear left wheel should help quite a bit.

The rubber bushes back there can look pretty bad, but they frankly don't do much. . .they are more for vibration dampening. Was your conical screw tight and wired down?

I have some spare side mirrors on my 1986 951 parts car - they should fit fine. PM me if you are interested.
