Super tuning car runs good shooting for great

Not a big fan of white grease for assembly lube. Clean the bores out with Marvels Mystery oil or WD-40 until a white towel comes out clean. Use a SMALL bit of real assembly lube on the skirts (maybe the size of a dime) and spread it on the skirts. That's lol you need on the Pistons.

That white grease makes heat. It also packs in the bearing grooves and cuts off oil.

I'd stop, take it apart and clean it all and start over.
