Lightbulb Second chance built bottom end.....again

The Story: OK I had to pull the engine all apart again after a full Cosworth build of the bottom end. After 4,700 miles my OEM oil pickup broke while I was driving to work. The engine ran for 3 seconds with the oil light on. So I tore it down to a short block and found some metal shavings inside the oil pan after spraying it out with break clean. Then I took the engine back to Out Front M.S. and had them pull it the rest of the way apart to find that there was only minor scaring on the crank but none on the H-beam rods. I also took the heads as well so they could be checked.

The Question: Everyone tells me to buy a new oil pump, oil cooler, and oil pickup. I already plan to buy a Killer Bee oil pickup but would like to try to clean out the oil cooler and pump if possible to save $400. I've already tried flushing it out with water and brake clean and theres no metal coming out. This is my second time doing this and its fun, but its getting too costly. Is there any hope of reusing the oil cooler and pump? Thanks for the input.

Clean/reuse the pump assuming it has no damage from pumping debris. Do not re use the oil cooler under any circumstances.

Change both the oil pump and oil cooler. You can NEVER clean those fully, no matter how much time you put into it. Just go new all the way. The risk is too great to cheap out on 400 bucks. You risk destroying another 2-5k motor.

I agree with Martin --disassemble and clean the pump,then pack it with assembly lube but replace the oil cooler.

I'm going to remove the oem oil cooler and ordered the shorter oil filter pipe feed for the 2.5i. I'll be running an external oil cooler with a canton sandwich adapter. Socal doesn't get cold enough to need the oem oil cooler, plus don't want to risk the motor from previous debris found after a rod knock and spun bearing from the oil pickup failure.

I cleaned it out too but I don't trust it and don't want to spend $200 on another oem oil cooler. It will also keep the canton oil filter and sandwich from protruding above the headers.

Well Out Front M.S. is hooking me up. The engine is done and the heads are ready. They also sold me the killer bee oil pickup, baffle and oil cooler to help make things cheaper. All together they saved me almost $700.

Work they did: Cleaned block, polished crank, cleaned heads and installed new seals, new rod and main bearings, new Cosworth 100mm piston rings, and the polished the cams and caps. They sold me an upper gasket set for $175 "so I didnt have to pay $250 for gaskets I probably wont use", K.B. Oil pickup, K.B. Oil baffle, and oil cooler. Paying much less than $2,000 for all. It was set at $2,600 plus taxes before. NICE!!!!!!
