Oiling issues

I don’t disagree with you, yet. I don’t have enough information to make an informed decision. Like which element is being used, what weight oil, bypass spring pressure, etc. But I will say that a typical oil filter will not collapse like that. And that in and of itself IS a problem.

I am learning a lot about oil filters over this issue. Oil filter cartridge is a professional products 10811 cartridge. I learned is a 10 micron filter. I’m using Lucas 20/50 full synthetic oil. I don’t know what pressure spring but cold start is 70psi.
