Have a set of used (miles are unknown) 4.6 Manley flat top stock bore pistons.. and a set of aftermarket rods that have no name. They could be Manley.. but not for sure. 450 shipped for everything.
Need some opinions.. I have a noise when the car warms up sounds like a bad valve or guide. I decided to do a oil analysis and the results have me thinking it’s a spun rod bearing with the high copper and iron numbers. (The high lead number is from some octanium I had in the tank)
