ive been hearing mixed reports about hot tanking a sleeved block. i know mine(aebs sleeved ls block) was hot tanked after being bored, and im kinda curious toward this. what would be some negative effects??? id hate to have my 1000+dollar investment compromised due to a 60 dollar hot tank

bump for info.....Im in the same boat

what are other options to get the shavings out after bore/hone???

ask the sleeve installer what they say. Golden Eagle say with the instruction/warranty included not to hot tank their sleeves

Oops.....well I had my GE hot tanked not too long ago after a refresher......guess I will find out if there are any negatives

when you put the sleeves in don't you have to deck the block and then hot tank it?

Sometimes hot tanking will un seat the sleeves and allow them to raise up a few thou. If you were to surface the block in that condition, the sleeves would then re seat themselves in a dropped position.

makes good sense. when assembling my bottom end the sleeve surface was a lil above the block deck surface. i had my head off about 3k miles after building the motor and everything was flush again. i have some slight coolant mixing issues which is why i asked this question

earl

you may need to tap the sleeves and resurface the block, not sure

I actually dipped my head into a bucket of drain cleaner (industrial strength) and It removed everything. Just let it sit over night, I did the same with my block. I am going to take pictures tomorrow and show everyone how it came out, so far the block looks really great!

This is what I was thinking.. Since the expansion rate of alumnium and ductile iron are different..

yea my sleeves were definately up a few thousandths when i got the block back, but as i said after having the head on there for a few thousand miles, the sleeve and block deck surface are both level wiht no evidence of sleeve sinking or anything.


here is my concern, im loosing coolant, it can see a lil of it in my oil when i change it, but it definately can be seen on my breather filter (catchcan doesnt have much coolant in it).

now this head was on my last motor when i blew my #3 sleeve to pieces. im thinking that i punctured a coolant passage in the head somewhere and its either dropping into my cyls a lil bit, or it is mixing with an oil passage in my head. the problem was worse but i changed headgaskets and it seems to have slowed down a lot, but not totally stopped. my machinist said that he didnt see any damage to the head when he was machining it after the motor blew.
