Does the head gasket seal against the top of the liners?

I have some "brand new" darton sleeves from a supplier on this board and they have dinks in the top, they also look used but they swear they aren't. Are they always like this?

Thanks

 

pics would help

 

Sent them these when they arrived:

 

They look second hand to me so I'm not to happy seeing as I was told they were brand new. Seeing as I'm in the uk and they are in the States I'm just looking at how I can recover them.

They also sold me inconel ARP head studs but I can't find any specs for them, do they exist? Also a bit concerned with the sealing of the block so will have to get that looked at.

 

if you paid by credit card file a complaint. have you asked to return them? i would send everything back. vivid hasn't got the best reputation .

 

HG will not seal properly, extensive machining, custom thickness headgasket would be required. The corrosion looks like it could be cleaned off with an emery cloth, but the dents on seal surface can't.

 

So I've been had then? That's disappointing. Do Darton sell individual sleeves?

 

The "rust" is not that big a deal. Or maybe it is. Depends upon how the sleeve is installed what the purpose of the grooves are at the top of the sleeves if the grooves at the top accepts some kind of o-ring or other seal.

As for the dings on top of the sleeves: The dings on the top of the cylinders are but I have to ask is after the liners are installed are they installed with just a bit of metal above the block deck and the deck is cut -- just a "skim" cut -- to clean the deck surface and bring the sleeve height down to the deck height?

If so this will remove the dings and also ensure the top of the liners are all flush with the deck and the gasket then should seal just fine.

 

There is no skim cut ever taken from the liner case or sleeve, they are supposed to drop in as is. The sleeves are held in place by orings, there is no rigidity to machine them in place. If you MUST machine them, they must be done individually including the liner case.

 

^^^ note that this is from a guy who has installed a few and also machined a few to remove O-ring lands that were no longer needed...

 

at this point i would call vivid and demand to send this mess back. if the liners were treated this way consider what the rest of this 4.0 motor was treated like

 

In that case then I would have to say the *liners* are damaged and unusable and the seller should accept them back.

 

I live in the UK though. Will cost me more than new liners to send them back.

 

new darton liners are 1800 approx

 

Well, thinking out loud if the rust/corrosion can be dealt with to then ensure the proper sealing of the liner perhaps a shim can be placed at the bottom of where the liner fits -- if this is already machined -- or if the block not yet machined to take the liners the depth of the liner bore machined just a bit shallower and the top of the liner then re-machined -- just enough to remove the damage -- and bring the height of the liner to match that of the block deck and thus these liners used?
