06 6.0 no base oil press--questions

[batmantech]

06 cranks no start, loud pop noise in intake-no icp, no base oil press. Inspect reg. looked ok pulled gerotor. The cover is heavly grooved both gears have deep gouges. My first question,What holds the outer gear in place, is it the cover? How much grooving can there be in the front engine cover? I see one groove in the top portion. What caused the damage? I would assume that it has to do with the loud pop in the intake. So I checked man. compression all 400 psi. The poping is from cylinder #7. I think somthing let go and it went into the pump, but what? And where else did it go?

Any thoughts? Or previous experiance.

As always thanks in advance!

I have a bus engine out right now with a similar scenario. #3 intake lifter is destroyed. The roller failed and ground the cam lobe. My gerotor gears have a few heavy impressions in them from a needle bearing, metal flake in the oil filter element and on the drain plug magnet. I cant get the lifter out of the block - we used a boreoscope today to survey the damage. The front cover is gouged which I attribute to the loss of lube oil pressure... of which I have none.

 

At this point for you I would access the valve covers and inspect the valvetrain...

I've had the exact scenario a few times. Personally, at this point I stop wasting the customer's money on diagnosis and call an FQR.

Absolutely. Where my engine is concerned, the piston smacked the valves, the turbo is "tight" and there are shiny flecks in the oil cooler reservoir - along with 2 panels in the reservoir screen torn up... meaning the HPOP and all 8 injectors are scrap as well. Gotta run the cost cap tool on Monday and get prior approval... like a trained dog jumping through flaming hoops into a pile of dog shit. <sigh>
