Probably posting this in the wrong section and the forum gods will hate me... but after my last oil change I noticed a small puddle on the floor.. thought maybe I didn't tighten the drain plug enough as that's where she was leaking so gave er another snug and yup it was tight. Figured maybe that washer was done and wasn't getting a good seal so went and got a nylon one and swapped them out quick without losing a pile of oil and gave everything a quick shot of brake clean. That's when I noticed there was a small crack in the pan where the threads for the drain plug are and it was seeping. I have another pan off my old motor but was just wondering has anyone swapped pans on these before cause I hear it's a hell of a job. Just want some reassurance of what I'm getting myself into... any info would be great

Good question. My 451's oil pan is leaking and I'm curious about the process too. Could make a fun project for my spare time!

From what I understand, one of the motor mounts has a bolt running through the pan and according to what MB dealers say it is a bit of a job. Before I replaced the pan with a used one, I would have the threads reinforced using a Time-sert or similar device. The original threads were aluminum and replacing them with a more durable steel thread makes a lot of sense especially with the oil pan off already. I have been told the Heli-coil brand thread inserts may not be oil restive and could leak oil. Something to verify I guess.
