Will hot tank get rid of spun bearing remains

CHEWY911 · 04-06-2009, 09:07 PM

Will hot tanking my block by the machinist get rid off all the particles in the oil galleries? I don't want to get another spun bearing after the build from a block oil passage or particles getting in the bearings. If not, is there a process that will?

Thanks guys!

it should. Any descent machine shop will have a step by step process to properly clean out a short block. Make sure you also address any oil cooler, lines, cylinder heads and such. Anywhere oil gets. And always replace you're oil pump when handling something like this.

do not re-use the oil cooler,if you had a lot of material floating around it is almost impossible to get it completely cleaned out.Also a good amchine shop should remove all galley plugs before hot tanking and then flushing all passages with clean water and then blowing out with compressed air. good luck

I TRY to always remove EVERY hex plug (the 8mm and 10mm) and bolt that the block has connected to it when have my blocks bored/honed and hot tanked.

I always cleaned the block myself after coming from the shop, too. I good set of pipe brushes help.

That is a must. I wouldn't just assume the shop doing the hot tanking will do this either so make sure you ask them or remove the plugs yourself.
