This happened after my last pass down the track

at first it looks like just a blown hg










Notice the inner sleeve is still in one piece. i'm thinkin the gasket blew so hard it separated the outter lining from the sleeve

btw this was a 81.5mm darton sleeved block
9:1 pistons
sc61 @ 26psi
~550whp or so (i dynoed 511whp @ 23psi)
I rode the limiter in 3rd too long (didn't realize i was on it... newbie mistake)

 

i've never seen a gasket do that.... damn

and you just seem to have bad luck with motors... is the inner sleeve ok from what you can tell?

 

fucked up sleeve job, who did it?

 

dosent even looked sleeved to me

Darton makes many different kinds of sleeves, infact they make lots of the sleeves for many places that sleeve them... they make those T braced ones and 'replacement' sleeves that would look just like the stock Honda ones...

 

the block is sleeved.it looks like they cracked the aluminum when they put the sleeve in.

 

i've never heard of a 'sleeved' block using the stock aluminum up that far, ****** is definatley not sleeved correctly with a full sleeve. Who sleeved the block?

"Dry sleeve" motor by ImportBuilders

"This is the sleeving style to choose for all motor applications, and for street cars with mild to moderate levels of boost. This sleeve is not as resistant to detonation and tuning problems as the flanged or the Darton, but has a thicker OD overall than both other styles. For example, if your going to boost 15-20 PSI and you are using pump gas and there is a chance you could detonate the motor, you want to step up to the flanged or the Darton mid. This style of sleeve has run 9's all motor, and has run 8's under boost. I have been on the dyno personally doing 40 PSI on these, its very strong.
OD THICKNESS:
B series: 89.5 MM"

the inner sleeve looks totally fine to me. the sleeve job was done by race engineering from what my friend told me (block came in the car i bought from him)

 

it looks like they made it press fit and cracked the aluminum when they installed the sleeve.

 

i've cracked a sleeve on my LS-T and it was A LOT nastier... there wasn't any inner sleeve that held up. it just blew straight through.

 

expletive marc thats blows

meh not really. i sold the shell a week or two ago and i've parted out most of the setup. the block/head/tranny and a few other accessories are the only thing left

 

Damn that is crazy...

lol i'm used to that. i swear my motors always break in the oddest of ways.

 

so can you still use this block since the inside sleeves looks ok?

dunno... anyone willing to chime in on that? if not this block is getting tossed.

 

try contacting Darton. they were very useful in assessing problems I had with a darton sleeved block last year.

yeah but i'm also willing to be that piece hanging off may cause the gasket to blow again from once it sees any vibrations from the motor running, etc.

 

well i guess you had to ride the rev limiter longer then 3 sec

 

wow marc - you always blowup all your sh*t.
