    Hi,
    I am doing a major service on my '86 3.2 and have the camshafts removed in order to reseal everything and do the valve clearance adjustment.
    I am really struggeling to get these oil seals out of the alloy ring. Is there any smart procedure? I have watched videos and read threads but I am getting the impression I am the only one struggeling. The difficulty for me is to put the right amount of force to the right place. I bet these are the original seals from 86, except one brown seal that must have been replaced somewhen.

    Any help appreciated!

    Support the ring on a suitable sized hollow cylinder in green ( pipe, socket, etc)

    Drive against the back of the metal face with a punch/chisel/screwdriver and hammer in red, be sure to get behind the lip seal, or just cut the lip out completely. Small taps in rotation around the seal, a little bit at a time, if you force the seal unevenly it may distort the ring.

    Ring in blue, punch in red

    Since you have the cams out, you could also reinstall the ring on the engine, clamp it down with the valve cover and the pry them out from the front.

    If all else fails, machine them out on a lathe

    Put it in a vise, use the seal remover to pull out the seal.

    That was the solution! It took a while to get the right "tool" to put the camshaft ring on. I found a 70mm in diameter ring from the food industry for food decoration. I german it is called "Schaumspeisering" :-D.
    I secured the camshaft ring with a zip tie to the ring and put a screwdriver in the oil seal and hammered it out. Very satisfying work... :-D
