Late jumping in here. Many years ago when I owned a 300C when I was 19. I pulled the motor and supped it up. When I started it up the oil filter leaked. Changing gaskets and removing pan to reduce oil pressure did not help. I had increased the oil pressure with more washers behind bypass spring that is why I reduced it. None of this worked an determined the canister bolt was bottoming out. I installed two gaskets and that cured it. I suspect the new gasket was just a little thinner and allowed it to leak. If you experience a leak I would grind the bolt down 1/8".

Rather than try again with the smaller thicker seal ring, I just put the larger thinner one that was the same as one removed. The thicker smaller one may have worked if not so old - it looks like it may have shrunk with age just enough so it was too small to pick up the lip of the metal cannister in just one spot - enough to not seal. If anyone knows if the thicker one was a genuine issue, I would still be glad to hear - it likely would usually work better than the thin one if not shrunk by time ?!! With a bit of spilled/wasted oil around, I shouted the engine bay to a quick degrease/wash, then did a quickie on the wire wheels, whitewalls, and all chrome/diecast - boy a red 300C with original style large centre chrome wire wheels, and sat just an inch or two below stock at the front, is a knockout, even if a 10 footer - at the local supermarket today (before I washed last few weeks grime off it), one person just wouldn't move so I could back out, until he had finished making sure I knew he loved it. I have had this car 28 years, and only really used it (sometimes/regularly) 'oftently' as a fun daily driver the last 10 years - what pleasure it gives. (I must finish my two others, especially the 550bhp Daytona Flying Mile 300C that has sat unfinished for the last too many months - both of these I owned for 10 years, yet driven so briefly.) May all 300 owners around the world please have as much satisfaction from using their 300s - this one of the true reasons they were indeed 'true/real 300s' - looks, quality interior and fittings, and industry leading performance !!!? If there is a bolt on adaptor to use 'spin on' modern filters, I may go that route - they are available for most 50s cars - I do not wish to go to a remote filter, as they sort of ruins underhood stock look?
