How to check for Head gasket vs. cracked sleeves/block?
I have a 04 Disco 4.6L that I just had the engine rebuilt on. A month later it is consuming coolant in cylinders 1,2,6 and 8, about an inch of the reservoir per hour of driving. There is no external coolant leaking. The shop that rebuilt the engine wants it removed and shipped to them to determine fault (Install or rebuild). The labor to remove and re-install the engine would be my cost. and I fear they will try to blame it on install and not cover the engine.
The engine was supposedly rebuilt with new top hat style sleeves. But I have my doubts about everything now.
If it's a head gasket I would rather just pay to have the head gasket replaced. it's almost the same price as removing and shipping the engine.
My shop can't say for certain without tearing down the engine.
They used a bore scope to diagnose which cylinders were clean, and which had carbon build up.
Is there any way to determine which it is without removing the heads?

no coolant in the oil. just shiny pistons.
I sourced the engine myself from out of state. They are looking to blame it on the install, and it was a parts only warranty anyway.
The shop that installed the engine is local, but they won't warranty the other companys product as they were not involved in the purchase.

what....
Maybe i am truley missing something..... The people who rebuilt it..." The ones who where responsable for torqueing all the head bolts and installing the head gasket.. etc..etc" are telling you that the people who just droped it in and reconnected hoses and wires, alternator are responsable for the headgasket or block leaking.... " Yea it must be the alternator... I would be beating on the builder...Sounds like they are already trying to pass the blame...
My 2 cents, Good luck... Chris

Yeah, I don't blame my local shop at all. I totally see where he is coming from. and obviously it's not their fault. That's why I know the machine shop is screwy.
The machine shop is halfway across the country. I thought about driving there too, but it's just too far.
Thanks Mike.

It's literally halfway across the country. 4 hour plane flight. and we don't know if it's the head gasket or a cracked block/sleeve.
