new built 1950cc engine with gt3076r

[turbotegs]

engine light came one once from temps, and the problem was before this

im not sure how the sleeves sit in the block, but i would have thought that there are two square edges that touch and once bottomed out, they wouldnt be able to move. or is there a wedge to square edge?

how can a sleeve possibly sink if the surfaces are both square to eachother? or is that the problem?

it sounds like the not square thing was my problem when they tried the second time, because they machined it themselves after bad results on the first try on the second block..

lol

I cant comment on how the dart block sleeves are located but i'm pretty sure they will have a flange at the top of the steel sleeve that locates into a machined recese in the aluminium block as per your first diagram.

As for the darton MID sleeves, if the machining and install of the sleeves are done properly there is no way that they can sink, there is a 5mm step that the sleeve sits on at the bottom of the water jacket. the usual issue is that the sleeve isn't sitting down hard when it is decked.

i've machined 6 blocks for darton MID sleeves and never had an issue and the block in my car was the first one we done and it has done 25000kms at 450+kw@wheels and it's never been touched.

In short all sleeved blocks regardless of manufacture are fine providing the workmanship off the install is perfect! Obviousily Slaz knows of some failures of darton sleeved blocks as do i, but it is most definitly not a fault of the design of the sleeve it is 100% down to the person who installed them incorrectly.

Anyway hopefully Scholzey has a better run this time round and we see the car out at the track again!
