I've read a bunch of the threads. I have a low end knock in my engine. I pulled the oil pan, changed the rear main and inspected the flex plate. All bolts were tight and no cracks, sprayed it with dye penetrant 4 times.
I also plastic gauged the mains and rod bearings while I had the pan off. They all checked out okay no huge issues that I could see for having 135k on the engine.

So I reassembled and torque all the bolts and sealed it all up. It was good for about 2 months, nice and quiet.
And now it's rattling again. Also the oil pressure has been dropping near zero at idle. So I'm getting ready to take the oil pan back off. I'm looking to install ARP rod, main studs, and a higher flow oil pump. Yes I have read all the threads on the higher flowing pump.
But questions is do I mess with changing the rod bearings? How do I size them? Also on the pump is a mopar pump worth the extra over the Melling? I saw the Hesco pump but it's 3x the cost of either.
