I bought a truck a couple years ago and then had to have a remaned engine put in with all of the problems fixed. I have a IPR filter and manifold on my truck, a couple weeks ago I had to change the water pump. After the change all the sudden my deltas shot up, at first I thought air bubble, but yesterday I was talking to the guy who sold me the truck and he said by chance have I checked the filter to see if it might be clogged. Last night I took the filter apart and found quite a bit of sand and small metal particles in it (Pictures attached)

This picture is from the filter I did 4 clean outs on the filter this is the final clean out with all metal particles removed from sand with a magnet.
This photo is the metal that was in with the sands.
This photo is both sand and metal particles together.
The first 2 photos are on a small cottage cheese container lid for size comparison.

I am gonna put the filter back on and see if my deltas go back down to where they were before pump change. I'm wondering if the old pump was just weak and not kicking up the casting sands and the new one being stronger kicked up the sand and clogged my filter. With that being said has anyone done a back flush on your oil cooler with the high flow filter and manifold on the engine. Would anybody be able to tell me exactly how to do it incase I have to back flush my cooler, or know of a site on the net that would explain how to with the manifold. Any and all help would be greatly appreciated. And Thank you in advance.
