With the modified sump, is the oil capacity reduced? Less oil that will become overworked oil - would worry me terribly!
I had a Merc Benz 300sl 1987 vintage and the reason the 3.0 six cylinder engines last so well is due to the huge oil capacity MB designed.
I worked it out once, it's about 79cc less capacity give or take a smidge (technical engineering term)
Not worth worrying about
