After chasing a leak on my 91 300D (OM 602) the cause turned out to be the ALDA. After removing and disassembling it's clear that the seal in the threaded base is leaking.
My unit is the same part # as shown in this
ebay ad .
The green seal in the below photo is leaking on mine.
The ebay ad has expired, the seller is in Australia and I'm in the USA. So I'm looking for an alternative to hoping the seller has a kit left and waiting 2 - 3 weeks for it to arrive.
Any suggestions?
