Fuel pump fun

[SemiSweet]

Well, oil sample came back with slightly elevated chromium levels ….almost got nauseous….proceeded to pull the valve cover off to check the cam and followers and found no issues. I then pulled fuel pump head to check the rollers and cam lobes on the pump and found a surprise.

I replaced the pump rollers and plungers about 50000km ago so I am not sure if it got contaminated or I didn’t inspect the pump well enough when I replaced them and missed a mark in the pump cam. Not impressed that I cannot rebuild the pump and reman is the only option.
