Leaking freeze plug & IP removal ?

[roberth58]

Freeze plug behind IP is leaking on 82SD. If I scribe the housing to show location of IP before removing it can I just replace it, lining up the scribe marks I made after replacing freeze plug. I dont want to have to retime the IP unless absolutely necessary, since then I'll be reminded that the chain has 4 degrees stretch so I may as well replace that, and its almost time to check the valves and I should do something about that leak around the oil filter cannister. It never ends. God I love old MB diesels!!!!!
