Any updates here fellas?
Good Looking "Lady" and Yes, Tampa Area was very Lucky with "Irma".. keep us updated on your Cars!
And Hello from Weeki Wachee
Are you next Time @ Reeves - Cars & Coffee?
Very nice cars you have !, love that silver on the 124. Congrats !
Ugh! Yeah, that is misleading. I believe the only rotor brackets affected were phased out of production before the first 500E rolled into USA. I've never seen or even heard of the old/bad rotor bracket out in the wild...Thanks Dave, appreciate the info. As always. The only reason I ordered the brackets is because of the fact that they make it look like you need them in the description next to the rotor. (See photo)

I see Uro parts in that box... PLEASE do not use those! Or any Uro parts, for that matter. You should not need to change the rotor brackets anyway. The Bosch stuff is good to go. Click here for a list of who is naughty and who is nice.
No need for dielectric grease is needed anywhere except maybe a tiny amount to help the wire boots slide on to the cap. I don't use any grease but that's just me. Main trick is when removing the old rotors to never use a ball-end 3mm driver to avoid rounding off the socket-head bolts. I like to use a SMALL amount of blue Loc-Tite on the single center bolt that holds the rotor bracket to the cam sprocket, and on the 3 small bolts which attach the rotor to the bracket. No need for anything on the cap bolts. Make sure to number the plug wires before removal, or move 1 wire at a time, to avoid getting the sequence wrong.

Make sure the oil leak is actually from the camshaft seal... oil can also collect on the bottom of the distributor cap from a leak at the cam advance solenoids, which is MUCH more common than the seal leaking behind the distributor insulator.
Got a photo of the leak?

What? I like all that.
Also, a tiny dip of valve grinding compound or similar fluid/grease abrasive on the male allen socket along with some tapping of the socket into the bolt will ensure removal of the allens without rounding out. Obviously, you need to be careful with a good clean up if re-using the allen bolts, or anything else you contaminate with the abrasive...

Luckily they all came out without any issues. The new parts came with all new bolts and the new Bosch rotors now have 4mm allen screws instead of 3mm which makes them a bit stronger.. I think.
The CAS is actually dry on the drivers side, which is the side pictured with the oil leak. The CAS on the passenger side however does appear to have oil residue collecting all around it but the distributor parts were dry on that side.
WOW - seriously? Bosch finally figured out they screwed up and fixed something? 4mm socket heads is awesome. Just don't over-tighten (that's where the dab of blue threadlock is handy).Luckily they all came out without any issues.

Change CAS on both sides and reseal the cam advance solenoids, then your are safe for a long time! And way easier, if you have anyway everything out already..
Unless there is a clear trail of wet oil coming down from the cam seal, they probably are not leaking.Post #24 in the thread below shows what was done less than 5 years ago. That would explain why the driver's side CAS is dry but don't know why the cam seal would be leaking. What's the method for repairing that cam seal?

If they are leaking, it will look similar to the photos in post #1 at this thread - note the seal itself is wet and oily, as is everything else around the seal:

D'oh! Yeah... that does look like the seal is failing.To me that's what it looks like. I had wiped off the area less than a week ago when I first removed the ignition parts to inspect. Drove the car a couple times and a week later this is what it looked like yesterday when I took all the parts out again.
...The reason I like the R1C rotors is because I've been using them on my full size SUV for quite a few years.
It looks like the seal may have some cracking at about 11 o'clock and again at top.

Thanks for confirming, Mike. I had found the same thing... the Bosch rotor Allen bolt socket heads are slightly larger than 3mm, but smaller than 4mm. I was never able to find any Allen wrench that fit tightly. Just make sure to never, ever use a ball-end wrench when torqeing down or breaking loose (ok for spinning them in/out though).CORRECTION: I was wrong about the allen screws on the new rotors. They appeared to be slightly larger and I thought they were 4mm but they are actually 3mm 8.8.
Mike, your home-made tool is awesome. What size socket did you use?
I hope it's just an optical illusion but it does appear the cam sprocket is off-center in the seal. If so, that is almost guaranteed to leak. The only explanation I can think of is that the dowels are missing between the front head cover and the cylinder head. See attached photos for the 2 dowel (roll pin) locations. Bad news is you have to pull the valve cover AND front cover to check this.
