Hot tanking

408maro · 04-25-2009, 02:05:22 PM

So I'm throwing my engine back together but not removing crank rods and pistons. Inside threw the lil holes it looks like the grand canyon is there anyway to tank it without removing those? I don't have the funds or tools for a full rebuild

Not too familar with the process but I wouldnt...I would think the cleaners or what ever is used in the process would damage the bearings and the polished surfaces of the components. What tools are you lacking? Bearings are pretty cheap and you can rent almost anything from Autozone.

agree'd, you can do a "full" rebuild with just new rings, bearings and gaskets and have it last without worrying about things. if you have a good socket set, torque wrench, and some wrenches, im pretty sure you can do it. CHEAP.

Agreed. I would like to add something though. Check the cylinder bores first. If they are fine, then hone and proceed.

Grand Canyon?? You mean the brown buildup in the cooling passages?? You can take a grinder to it but it's probably no worth all the hassle.

i think hot tanking damages aluminum/magnesium...i'm sure that would include your pistons.

Just because you disassemble the rods from the crank and crank from the block to clean the block of its "Grand canyon?" stuff doesn't mean you must use all new parts IF you are 100% sure the used parts are returned to their pre-disassembled location.
But since a Re-Ring kit with bearings and gaskets is a little over $100 from Sealed power, why not use new bearings and rings.

Agreed, If I have it that far apart I would spend the $ on a hone, rings and bearings.

all that stuff adds up especially the deposit for autozone. all $$ i dont got. yes i mean the coolant pockets but i know i should tear her apart and do a full rebuild since im changing everything minus bearings and pistons,rods. but just dont have the funds for all that

Most hot tank solutions are caustic, remove oil, paint and sometimes rust. Anything that is not iron can get eaten up pretty quickly. The additional reasons to remove everything including frost plugs and galley plugs is so that the solution flows into every nook and cranny without problem and, more importantly, comes back out. I am not sure that I understand your original question or what condition the little holes you refer to are actually in? Be a little more specific and you may get a better answer.

none of the holes are plugged I mean If you look through the waterjackets inside the block looks like brownish old buildup.

How about removing the lower drain plugs ~ Sqaure headed (some times hex headed)~ pipe plugs near the oil pan rails near the center of the sides of the block.
Agressively use a coat hanger ETC in knocking out the gunk.
Flush with water etc.

That's a good idea and will do that thanks for the great advice

I bet there is some sorta acid that would eat it up.

I had one block that was rusted up with gunk so I stripped the block of the internals poured about 4 bottles of CLR in it let the sucker sit for a few hours and wow did that clean it out. The driveway did look like a mess afterward though.
