Here's one I haven't seen before...

I've got a 2007 F series with a 6.0L that just shut off and wouldn't restart. ICP pressure was only building up to 220 PSI while cranking.

It's a side job so I had some spare time this afternoon to take it apart today. You know the plastic support on the inside of the IPR screen? That little black plastic piece broke off and is stuck on the inside of the IPR, and the IPR screen has. NO holes it it at all.

I thought it was kind of weird.

was the screen pushed in at all?

Not at all. It was separated from the IPR though.

Hmmm well I guess anything can happen. I recently rescreened my IPR just for piece of mind. There is a lot of pressure flowing past that thing.

I do that with EVERY oil cooler I replace.

Same here. I've also made a habit of pulling the pump and blowing out the passage. If it needs an STC it gets one, if not I just reseal everything

Ive had a few that seperated, i use a small hook in the hpop cover and it will usually get it out. I see alot of trucks in my fleet that have failed iprs, usually its from someone recently doing a egr/oil cooler combo and i guess loosenes some grit
