I would hot tank those as well but not together. If there all together youll miss areas of each part.

 

i tore the block down already! thanks

 

Hot tanking is for a Cast Iron Block. Cold Tanking is for an Aluminum Block. Take it to a machine shop that knows the difference.

Hot tanking uses an acid solution to get the block clean, this will usually destroy an aluminum block.

This is not an absolute though there is such a thing as a eco-friendly hot tank process.

Before you get it done ask your machine shop what they use, and will they guarantee that it will not hurt the sealing surfaces of the block.

There are chemicals safe for all metals, and there are caustic chemicals only safe for cast iron. Both are used in hot tanks although sepretly.
I know because that used to be part of my job, cleaning up engine parts.

I would hot tank it all together (in a tank with the aluminum safe chemical)

Exactly what i was saying. My point was that he needs to make sure if hot tanking he needs to make sure they are using Eco-Friendly chemicals so not to hurt his block.

 

allright thanks guys. I'm getting this thing hot tanked at my friends uncle's shop so i'll ask him. and if it his eco-friendly i can put in my crank, girdle, and w/e in there then right?

 

There should be no problem. Make sure before you hot tank you have all the hondabond off all the parts. like where the main seal plate and the oil pump match to the block.
