I picked up my ls block yesterday that i sent to install the mid darton sleeves when i got home i found out that the first sleeve was totally sealed agains the block but the other three have a little gap around them. (top view of the block) Maybe it was cutted too much (like a milimeter) at the machine shop. First time using darton sleeves. Is this ok? Sorry i couldnt upload the pics!! any experience?? any advice??

 

advice?

upload pics

 

I also have a darton sleeved block. i have the same thing. the headgasket seals it off anyways so i wouldnt worry. Works wonder for me with a metal one of course i have a b20/v

here is what mine looks like. super shiny sexy i know lol



yeah they are bullet proof so i wouldnt worry about reliability hahaha

 

i have some in a block out in the garage that has a chunk out of the bottom of #4 lol

 

i have a fully built 84mm darton sleeve sunk # 4 sleeve 4th dyno pull,, there only good if the machine work is done 100% correct and most local machine shops will **** it up, thats where i went wrong i took it to a shop who specialized in v8's locally to me instead of shipping it out,

 

Maybe adding a ''O'' ring groove would help.
Just a thought, It may make things worse although
What is the bore size?
Most machine shops will not admit they cannot do a job properly.
We offer in house sleeve install only to regulate the quality.

 

Who installed the sleeves.

 

gotta get a good machine shop

 

If I understand well, the machining process leaves a lip that the tapered edge of the new sleeve sits on, approximately 1.5mm to 2.00mm, you then add APR hardware and torque up on these small lips.
so long as the machining process is perfect and the block doesn't contain any porous area's on the finished lip you have half a chance.
