K1100LT Ignition oil seal
- Thread starter walt3022
- Start date
Hello,
I believe the seal is removed and installed from the inside of the timing chain cover. Below is from the workshop manual. It's been a while since I've done this repair and it sounds like a lot of work and a bit messy, but it's not too bad.
That means that you need to:
• Remove ignition cover
• Take off gasket
• Remove Hall-effect signal transmitter, noting
the semi-circular shim washers.
Note:Mark the correct installed position of the adjusting
washer on the engine block, or remove it in the TDC
position.
• Remove gate rotor and take off adjusting
washer.
Remove the crankshaft cover
You'll need to drain the coolant.
• Detach the coolant hose at the water pump and
radiator.
• Remove screws and the cover.
Removing cylinder head cover
• Remove the ignition leads.
• Remove screws and the cylinder head cover.
Removing and installing sealing ring in timing
case cover
Remove screws and timing chain cover. I believe the cover is sealed using RTV silicon and may be a bit hard to remove.
• Drive the sealing ring out with a suitable drift.
• Drive the sealing ring in from the inside using
handle, BMWNo. 00 0 500, and drift,

ignition oil seal
Thank you for your reply, Richard. I must have used the incorrect nomenclature for that seal. I cannot imagine that the steps in the description are necessary. Removal of the valve and crank covers?! Why? I've done further research since I posted the original question. I now believe the oil seal can be replaced without even the removal of the timing chain cover. The only issue I foresee is whether the seal is the newer, Teflon type or the old, conventional design with the spring. I understand the former can be a bit tricky to install as the lip can easily end facing the wrong direction and subsequently leak.
Hello,
As I said earlier, it's been a while since I've had to replace that seal, however, the BMW workshop manual states that the seal is driven in from the inside. If this is indeed the case, then both the crank and valve covers are removed because they seal against the ends of the timing chain cover. Obviously, if the seal is replaceable from the outside, then none of the covers need removal.

That's the way I proceeded and so far all is good. No sign of an oil leak at this point. I hope I can say that after 20-30 k miles.
