Metal Debris in Oil... Now What?

[Jake Raby]

At every cold start your factory filter is bypassing oil straight to the main and rod bearings.

See how much of the material is ferrous and let's go from there.

Kurts German Autowerks is my porsche guy in homer glen. Used to work for bunch of dealers now has his own shop. Hes busy so call him but he's a good expert opinion and he charges half of what the dealers do.

What does the oil filter look like? If that's metal in the sump plate, there should lots of metal in the filter.

In my rod bearing event , there was copper/gold debris in the pan and the LN spin-on filter.There were two larger pieces on the oil pickup screen. Next place to investigate will be the oil pump and scavange pumps.
Interesting was a large (almost a teaspoon size)soft lump of black sludge (Moly powder?) on the LN magnetic drain plug. I am wondering if that blocked the oil gallery/feed to the rod bearing. Only a complete teardown ,clean and inspection will tell.
I am determined to find the cause of the problem instead of just muttering about P cars. I'll post photos of what I find so it adds to the fund of knowledge on the Forum.

This debris looks a lot like what we see when cams/ lifters are failing. The problem is this has been circulated through the entire oil system for a long while by this point, and no, the oil filter has not filtered 100% of the oil.

These small dust like particles are more harmful in the oil than chunks. Why? Because they are light and fully suspend in the oil, allowing them to be delivered engine- wide, creating collateral damages that are extensive.
