I am, still, in the process of replacing my headgasket on my 91 300e and am trying to put the camshaft seal on the timing chanin cover. silly me i forgot how it came out. it was stuck on with gasket maker and i had to spend a long time scraping and tearing the old one out and forgot how it was installed.
I am unsure, does it go in from the front of the timing chain cover( dosent actually fit, seal is to thick) or does it slide in from the back(fits perfect and snug)? I kind of remember the old one being installed from the front cause i am still scraping gasket maker out of the center grove.

thanks in advance

it goes in from the front, becareful when installing the cover, the seal needs to be eased over the cam,

do i need to lubricate it to get it in? it is a little small and will not for the life of me squeeze in.

you need to drive it in with a seal driver, or a socket of the same size as the seal, it should be flush with the housing. no lubrication necessary
