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,
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,

Hello,
I found a picture of a used timing chain cover on ebay and it does indeed look like the seal can be replaced from the front.
