Sean,

My understanding is early models may need valve guides and not only seals. These M103 engines can leak lots and never get a drip on the floor.

Really- have ladies not wanting to fix the oil leak, but please keep the oil off the tail light lenses. Almost that bad.

At 188k, an untouched M103 needs a valve job probably. Lower ends are quite strong and should not need to be rebuilt. Note that you should only use a Mercedes purchased head gasket. There has been many revisions and the dealer will R&R it if it leaks-regardless of whom installed the gasket!!!

Also, note- mercedes don't take to re-ringing like a chevy. If you pull the engine plan on finding someone familar with MB's to bore the block and install oversized pistons.
