5.3 lifter problems
Hot tanking will only do so much. You need a set of brushes to clean out the oil galleries in the block.
If you find metal contamination issues, Throw the pick up tube and Oil pump in the trash and get new ones. I have tried several times to clean the pick ups and just when you think it's clean another spec of metal shakes loose. you can never get it all out of the screen and it's not worth trashing another motor.
I'm loowing forward to doing it the way I should have done it in the first place.
BMR make a nice comprehensive kit part number 1-E KIT.
You can also get a basic kit from Moroso and a few other places.
depending on the market in your area it might be cheaper to buy a junkyard pullout and either run it or get it refreshed
