I have done a search and am surprise I don't see too much info on this. The info that is there is not specific to what I am experiencing. Is it just me???

I have plenty of experience doing the u-seal on the M103. But I have a M104 apart for the same job and am having great difficulty reinstalling the cover while keeping the seal from sliding out of the groove. It seems that the problem is the chain guide pin which forces the cover to be lower than I'd like it to be. The result is that it scrapes the u-seal off every time. I am getting very frustrated.

I know I could spend 8 more hours trying to finesse this seal into place. I'm worried that the black sealant will dry if I let it sit overnight.

Can the experts please share any tips to finish this job? I am so so close...

Do I need to remove that pin? It doesn't look like that would be a good idea, as the chain guide would probably give me some real problems reinstalling.

HELP!!!
