Actually, you're both correct. The E34 rear head restraints go through the leather of the seat, into brackets mounted to the rear bulkhead. You must remove the head restraints before you can remove the rear seat back. The procedure and parts described in the write up in question, will not fit on E34 Touring. There are head restraints available for the E34 Touring, but they mount into the seats, and have a lower profile so that the seats can still be folded with them in place.

The car has 105k miles and checks out on Carfax. It is a 5 speed manual. This will be my friends first BMW so I would like him to have a good experience. He has driven it and is very favorably impressed. He will be buying it from a used car dealer, so no maintenance history. I have owned many BMWs but never an E32 7 series, so have no personal experience to rely on.

Let's make sure we're talking about the same thing, I'm talking side-to-side weight transfer, and I'm talking about a setup for 9+/10ths track use. In an open-diff FWD car you want to decouple the front wheels from one another to as great a degree as reasonably possible, so as to keep that inside wheel on the ground at all costs. > But this is a loosing battle, a FWD car needs limited slip > more than a RWD car does.

Someone used to driving RWD cars fast won't much like the feel of an open-diff FWD car set up for track use, you end up running stiff front springs and a ton of rear roll stiffness and the end result is a very fast car but one with little room for adjusting your line once in a corner. A speed-limiting limited-slip (e.g. viscous, etc.) will help this, but you won't get a lot of throttle-steerability. A Quaife/Torsen-type torque-limiting diff is a completely different animal - - since you will get more pull at the outside front wheel (which tends to pull the nose in around the CG) you get a very great degree of throttle-steerability, you can use a reasonably balanced chassis setup, it's a lot of fun.

As you suggested I took off distributor cap, rotor and plastic shield and found just a trace of oil in the housing (on the head). Nothing major just few small wet spots. Now I am leaning towards head gasket �letting go� since head is �wet� with oil right in the area of cyl#1 � side and front towards exhaust side. I did compression test just for the kicks ( don't have equipment for leak down test): #1: 150 psi #2: 150 #3: 150 #4: 170 #5: 142 #6: dry: 110; wet: 120 I did the test with chipo gauge (so I am not sure how much I trust accuracy) and repeated it 3 times per cylinder. This test shows that cyl.#1 is ok, but there might be issues with #6, and #4 might have some excess carbon deposits(well, there might be issues with other cylinders but since I did not do leak down test...) Anything else I should look at? Suggestions?

If you don't find oil behind the shield, then your cam seal is not leaking. If it is leaking, then you simply unbolt the seal carrier from the head and throw it away. Get a new seal carrier, carrier O ring, and cam seal, from your BMW dealer. Knock the seal into the carrier with a hammer, install the O ring and install the carrier in the head. Once upon a time, I'd have said knock the seal out of the old carrier, but the last two that I tried that with ended with seal carriers that were broken in two......

Later weight transfer depends only on the track width, cornering acceleration and center of gravity height. Lateral weight transfer distribution can be altered within reason by having a higher roll stiffness at one end or the other. Both anti-roll bars, and stiffer springs affect roll stiffness. If your car weighs 3000 lb, has a CG that is 18 inches high, a track of 58 inches and is cornering at 0.9g, the total weight transfer from the inside wheels to the outside wheels is 838 lb. That number can change only if the above specs change. If the car is square and has 1500 lb on the left side and 1500 lb on the right side, then in that corner, it will have 662 on the left and 2338 on the right. Suspension tuning can distribute that 838 lb between the front pair and rear pair of wheels. Maybe 700 transfers at the front, or 500 transfers at the front. This is adjustable. Springs and anti-roll bars both affect this weight transfer distribution. Any type of limited slip will put more pull on the outside tire. The differences lie in how they get there. A clutch type puts more torque to the inside (slower) tire, until it begins to slip, then sends a % to the other. A viscous coupling does the same but in a smoother fashion, sending less to the slower tire and transitioning more smoothly. A Quaife or Torsen sends equal torque to each until one begins to overspeed the other, then transfers just enough torque away from it to prevent the overspeeding.
