After reading this post I'm starting to worry about my 86 300E that's just coming up on 137K miles.

Sixto, you stated the following:

"- there was an oil feed line redesign. The manual says to use the later design. I don't know part numbers but I believe this was settled in the early days of the M103 so a 300SE/L (88-91) should have the new design."

Is this an inherent problem on early M103 engines as regards the oil feed line? Would it be prudent to update the oil feed line to the later spec? Where is the oil feed line anyway?? Any idea on cost if I do it myself?

Thanks for any advice.
