Flushed the cooler and lines with mineral spirits... Others may not agree but I would never reuse oil coolers or oil lines once I metal has been introduced. May have nothing to do with your pressure but probably does have to do with you finding metal this last time. And yes I too learned this the hard way.

I just got off the phone with Melling.. He feels it's likely the pickup is too close to the bottom of the pan or crappy design of the Summit Racing one..

.. Their pickup is $11... be nuts if that's all it takes.. Guess I'm pulling an engine.. again... gettin' good at it.. can have it a couple hours..

Have a feeling my metal is coming from the distributor gear.. had noticeable wear on the gear for only 20 hrs...
My distributor is a bit short. Cam is meshing on the lower half of the gear..
I FINALLY found a slip collar distributor that will work with my EFI....

that amount of metal you found does not sound good, if engine had issues before(killed bearing) and whoever did the engine did not get the oil passages cleaned properly it will kill new bearing quickly(found out the hard way on a boat I bought with fresh rebuilt engine), so if you are pulling pan ck bearing #1&2 rods take it hard 1st along with rear main it seems

Are you using a Gen 6 double roller timing chain? If so you must clearance the front of the block as the chain riding on the outside of the cam sprocket will rub on the block directly behind the sprocket on the right hand side. Ask me how I know this haha. That ends up being a really good cause of fine metal in the oil.
