what are some symptoms of the sleeves sinking. my brother has darton sleeves in his integra and is having serious over heating issues. he has put 4 headgaskets on it in the past 4 months. resurfaced the head every time. this last time he had to get a new head because it was past the service limit. car does not over heat until you boost it. then it pressurizes the [freak] out of the radiator and boils the antifreeze. our next move is to have the block resurfaced. he is nervous that his sleeves have sunk.

 

is water getting into the cylinders? what do the plugs look like?
you can pick up a machinists straight edge pretty cheap to check
if your head or block is out of spec.

 

i think its the same symptons as a blown HG because it causes frequent blown HG's. check the oil look for water.
do a coolant pressure test.
check the deck surface

 

do a leakdown test.

 

well i already know the car has a blown headgasket. so what would a leakdown test tell me? is there anyway to fix sinking sleeves? or do you basically just have to get a new block?

 

you will have to send the block back to the sleever and they will replace them. most do it only at the cost of shipping, who sleeved your block ? PM me if you dont want to post their name publicly

 

symptons will be alot of blowby, oil turning greyish color and smelling funky, white foamy crud under ur oil cap.

 

thanks. ill look into that. we arent getting much smoke. just pressurizing the radiator

 

pull the head and throw a straight edge on the block. all of your symptoms are exactly what i experienced when my sleeves sunk back in the day when i had a local machine shop do a sleeve job

 

same thing happend to my buddies motor, he had darton sleeves instialled at a local machine shop. went through 14 headgaskets.

 

Yea I'm overheating a bit, and burning a bit of coolant right not during hot days over the summer, but I'm hoping mine is just headgasket related as I still have all my power and the coolant burning is minimal.

I believe its the fact that Cometic is FTL on hondas...

 

it your sleeves i had the same problem for over a year. they were sunk like just enough so when i got into boost pressure would build up at the therm. then shoot back out the over flow. tell pull the head and check the sleeves.

 

my cometic seals perfectly fine at 45lbs of boost on my car. been using cometic gaskets the last 3-4 years.

 

Yea I have read several threads where people have had no problems with their Cometics, but I've also read many threads where they do have problems and then switch to the GE overbored and everything is gravy.

I'm hoping mine is headgasket related. I plan on pulling the head off maybe next weekend and swapping HG's and seeing how she goes.

 

ok well would decking the block make the surface true again? or is there not enough material to deck the block down enough? and would oringing cure it? he bought the car as is and we cant find out the information on who sleeved the block. i wonder what a reputable shop would charge to redo it. maybe they can use the sleeves we already have?

 

from my experience, if you simply redeck the block it will become true again temporarily......and then the sleeves will move again shortly after and your back to square 1.

my solution was have ERL sleeve me a block and ive been good to go ever since.

 

well they use some kind of epoxy to set the sleeves right? do you think i could send it to darton or ERL and have them re-epoxy it and then have it trued?
im just trying not to lose a 1000 dollar block completely

 

bring it back to whoever sleeved it

 

^^^well if i can figure out who did the sleeving then i will.

 

its pretty hard to have a set of say darton mids sink due to there being 2 ledges the sleve sits on instead of just sitting flush against the bottom like a stock sleeve.
the block would have to be machined wrong or sleeves would have to have been installed improperly.wich darton seeves does he have?

 

these arent the mids.

 

If you send it to the machine shop, they will need to make a spacer that just covers the sleeves, put a torque plate on it and try to drive the sleeves into the block to sit them on the ledge. Wait 2 or 3 days, heat cycling them every couple of hours and re-deck it immediately after pulling off the torque plate off. If that doesn't work, you probably have to find another block to sleeve.
