i have a ls block that's been in a body shop and its dusty all in the inside...as in with the oil pan off its all dusty inside...how should i go about cleaning it up before installing it...should i use brake parts cleaner then wd40? or will that stuff mess up the bearings or something?

 

Take it to a machine shop and have it hot tanked.

 

Best way to get it cleaned properly.

 

Whats the going rate to get a bare block hot tanked?

 

Purple Power, $5.99 a gallon.

before



after

 

That cleaned up pretty well

 

Last one I had done was $15 bucks but now its free at work

 

OMG man what happened to that thing? Looks like someone used it for a night at the Outback Steakhouse





Is it me or does this strike a resemblence to anyone else?

 

Wow, where the hell do you find that ---- and how long did you soak it and did you use a pressure washer?
