Hi everyone Im brand new to this forum, This is my first post.
So I have a 1976, W115, 300D. The problem is when i bought it from some dumb kid who got it from his grandmother and did not take care of it, he managed to spin a rod bearing from running with no/low oil-_- So its number 2 bearing that spun, She still ran like a dream (not driven) started easily ideled smooth also the oil pressure was even all the way to the top, but had a terrible knock, Here is a vid to hear her


Pulled out the engine and trans took out the crank and The journal on num 2 looks pretty bad, definitely going to have to be ground but the others are in really good condition from what I see. Just took the crank to a machinist yesterday haven't heard back yet. So I will need oversized bearings right? or should i get a new crank. If so for wich ever one. Where can i get oversized bearings for this engine i cant find any just the standard 52.00, and if i need a crank, WHO HAS ONE! I reeally need this car done Im only 18 and took on this project knowing it was going to take some work im finishing high school early and I want to star school asap and need her done, it saddens me seeing her sitting in the driveway PLEASE TRY TO RESPOND ASAP Ill post pics of the bearing and the crank when i get it back
