It's the one pictured in your procedure quide-page 8, inside of the larger O ring on that cover. I think it just screws out.

...that shows it, right click on it and choose "properties" and then copy the address (highlight it and press "control + C" and then post the address over here so I can see which one you are talking about.

Or just give me the number, should be something like TBP52.JPG or something like that.

It is the seal inside of the one that says "replace this seal."

But I imagine you would pry it out and then have to set it back in place with the correct size socket or something of the sort. The socket is an assembly aide.

I wouldn't risk digging it out. Leave it, and if it needs replacement in the future it is relatively easy to get to.

Left hand-drivers side cam tool fixture is on. I removed the drivers side cam sprocket and timing belt, leaving the passenger side sprocket on so I could turn the camshaft to proper position. Before I removed the RH cam sprocket, I marked a tooth on the passenger side cam sprocket with a guide just for the hell of it. After removal of the left cam sprocket and the timing belt, I noticed the right side marks on the sprocket did not match up with my mark. They were off by about 1/2" and the sprocket would not turn back towards the mark. It stops. In any event the cam tool fixture will not go on the right side. To match up with the tool it appears the camshaft needs to go back where I am getting resistance. What is the next step? How do I move the sprocket without damaging valves? Could the crankshaft have turned? Could something have moved?

Just find out today that our camshaft seal just went. Would switching to synthetic aggravate a worn seal? We have a '98 A4 2.8 w/ ~62k miles.
