Block sleeves ?

Block sleeves ? - 09/02/13 06:06 AM

Well my season is done, unless I can get my old motor back together ! Thought I lost a head gasket, so I tore the top end apart and replaced them got it back running only to have #1 fill with water after about 10 mins running ! Pulled it out and tore it down today and found a crack in # 1 from the bottom of the cylinder to about an inch from the top ! All the way through to the lifter oil galley ! I don't get it I babied this motor, never shifted above 6800 rpm foot brake, never sprayed nothing ? I even did everything that I could to prevent this from happening ! I had a 3/4 fill, girdle studs line honed you name it ! And it still broke !!!! You all don't know where I can find a 400 block ready to go ? I was going to stick my old 440 back together and just go run 10.90s with it but I don't know if I have enough time before Norwalk ! Oh well maybe I will just run my 2010 charger and try to have fun ! Does anyone know if you can sleeve a filled block ?

I don't see why you couldn't sleeve one.
Unless the walls were way too thin to start with , it should work fine.

I have a std. bore 400 block with aluminum caps that is fresh off the line hone ready for cam bearings and caps. PM me if you are interested.

I have a 499" short block with cam but it runs 9.80 to 10.20 in a 3500 lb car with Indy -1 heads and a 1050 carb.
I would just sleeve it,

Theres more to this repair than just a sleeve if its cracked into the oil passage. Get a new block

Bob, can you even sleeve it with cement in there ? Also I think it may be cracked in the oil galley !

Then , as Colonel Trautman told a young and confused John Rambo......" IT'S OVER , JOHNNY !!! "
A cracked cylinder wall is one thing. But into webbing or the valley makes it worth about .02 a pound.

If you can check the oil galley with pressure and see that it is not cracked have it sleeve with a ductile iron sleeve

BTW, what makes you think it is cracked into the oil passages

Make sure the machine shop you have do the sleeve leaves a small machined step on the bottom of the cylinder wall for the new sleeve to seal against, don't bore it out top to bottom

If you are going to sleeve one cylinder and not bore the others make sure you check the cylinders next to the sleeved cylinder to make sure they stayed round. Most of the time they will go out of round.

They will be out of round every time.

Yes, if they are press fit. They can be made with appx zero tolerance if used with a top flange to seal and clamp, then it will not affect the neighbour cylinders. My

The filled block should take care of some of the distortion, don't you think?

I would buy the prepped block, and not even try to patch it. JMO

Maybe, I am not sure, have never tested it. But if the filling is not all the way it is hard to avoid distortion where the filling is lacking. Another issue with filling is machining out for the sleeve if it gets through the cylinder it will hit the concrete and damage the tool bit.
I have tried with press fit of as little as 0.001" and even this distorts the neighbour cylinder, so in a quality build a press fit sleeved cylinder demands oversize on the others. There are exceptions like diesel engines and engines with massive material around the cylinders, they hold up better... Not typical the compact V8 style.
