This is not my motor nor did i build it...thank god/benson Anyways this motor was supposedly sleeved by GE but I am not sure yet. I talked to Robert at GE and he said they only did an open deck sleeve for a very short period of time about 2 years ago but it is a possibility it is theres since it is o-ringed and they are one of the few who use o-rings. This motor was only running for a couple hundred miles and had a severe problem with pressurizing the cooling system and there was a bit of white smoke coming from the exhaust under load. As u see in the pics the sleeves seem to be cockeyed a bit and there is anywhere from a .006" to .010" gap between all of the sleeves. the owner of this motor does not know anything about it either. It appears to have endyn pistons in it and is 81.5mm bore according to my caliper. there is also some BS blockguard in there as u can see. i also checked the deck with a straightedge and everything is sitting up evenly. I contacted GE with pics but havent heard back yet, any ideas or thoughts would be appreciated.

 

Sleeved with a blockguard and O-rings? WTF?

 

Dave. I would have to see the block but it looks like an OLD Benson OR JG sleeved block with a block guard

 

stock sleeves with o-rings (wtf)
and an ac autotechnic block guard.... farthest thing from sleeved

i spy a scammer block

 

i have a block that looks just like that and its one of the first Benson blocks.. the sleeves have a gap between them just like yours..

 

Yup. Dave. If you want you can ask X to come by and compare to his while we have the head off

 

I talked with Earl and he said this was one of the first Benson blocks that Benson did and said the gap is not big deal..

 

what kinda psi are you looking to psuh with that block

where did i say anywhere that it was stock sleeves??? theyre not stock obviously, stock sleeves cannot have gaps between the sleeves as the outter part of the sleeves is aluminum and is one piece casted into the block.

I do not understand how it is not a big deal

 

REPLY from GE:

"there is definite problem there i would say to resleeve it if you want to send it in if its our sleeves we will charg 450.00 to resleeve it but thats the onlything i would know to do"

any other input?

 

Pull the block guard, have it decked & bored, and hope for the best. Assuming the sleeves are in there good, they shouldn't wiggle - that's be the only issue that'd affect decking & boring. Otherwise as long as the bores are straight and the tops are flush, the sleeves should take lots of power. If nothing else, have them step the block (sleeves very slightly higher), that would really keep them from moving, but at the expense of possible coolant leakage [to the outside].

You also want to run a good mixed coolant, as straight water will rust them badly, and the rust between the sleeves will easily push them apart.

 

Spend the $450 and have it re-sleeved.

thanks but its not my motor and its in st pete

 

IMO i have seen other sleeve blocks with slight gaps between the sleeves. i dont forsee how that can become a major problem.

as your block is O ringed which is a better way of sealing the headgasket, i cant see how the gaps would hurt the sealing of the HG

 

I dont know what the gap is between X's cylinders but he was able to make 529whp 354ft-lbs @ 25lbs on the old setup

 

do you think that the gaps effect the structual integrity of the overall motor, or thats its just a cosmetic effect? that they arent flush?

i was also told by our engine builder that they look more like old bensons sleeves but would not know tell we seen it up close or if you give me the numbers off the block we can see if we did it or not

 

talked to robert at GE and is is definitely not a GE sleeved block. Im gonna replace the o-rings and the headgasket and see if she seals up. thanks for the help!!

Check the deck surface as well. You happen to have extra copper wire?

 

boobie looks like mine

 

IMO it looks to be just a cosmetic thing mostly. dont see how it could effect anything unless it was improperly intstalled other than the sleeves not lining up perfectly

 

I wouldn't trust it. Get it resleeved.
It better to do it know since it's out of the car. Then putting it back in andtaking it out again

 

its in the car, heads just off

 

Not sure whose sleeves are in there but a block guard would never fit with any Benson sleeve. From the posted pix, I don't see any reason why you should not run that block. Some of the ugliest blocks make the most power.
