Question for the techs

Is there any way when you do an oil cooler replacement something can get down into the oil pump and damage it. The reason I ask is I did a cooler replacement and when I tried to start it just cranked. Took it to a ford dealer and they said something go into the oil pump and chewed up the gear. I'm just curious because when I did this I took great care no to drop anything. Every nut, bolt, and clip was accounted for so I have no idea what could of gotten in there.

So, they took it apart and showed you the broken parts?

It would make sense (I think) that if it was you, then when you turned the key it, it would have started and only got damaged after the item got a chance to run through it.
If it only cranked and never ran then I doubt any damage to the oil pump was from this repair.

But I'm no tech

Are we talking about the low pressure oil gerotor? Do they have it apart physically to show you the broken parts? If so, can you post photos?

And, what is the "SOMETHING" that got lodged into the gear? Can you post a picture of that too?

That was my thinking as well.

They were supposed to show it to me when I picked it up but I forgot about it because they had the bill several hundred dollars over what they quoted me. All he told me was it was chewed up but they did not find any thing in it. The truck has a bad injector now as well which it did not have before the cooler replacement. A new injector will be here Tuesday to take care of it.

As in a bad injector that blew its top, and pieces of the top passed through the oil pickup and took out the pump? THAT would make sense. If that is the case, it had to be a pre-existing issue that you were unaware of either prior to disassembling everything up top, or just happened while you were doing the oil cooler replacement. Did you have the high pressure oil pump cover off, during the oil cooler replacement? It would be nice to know WHAT passed through the oil pump gear, because if it's a needle bearing from a failed roller lifter, you are in for a BIG repair.
