sounds like from their description of the block they sell that atlantic british is convinced that the sleeves slip. crazy.

 

All that article prooves is that the block cracks near the head bolts and that there is a lip at the bottom of the cylinder to hold the sleeve in place (which it probably needs especially since it's tapered and just pressed in there). I don't know why they had to cut a block in half to show this, but it looks cool. Once the block cracks I bet that sleeve would start to get pretty loose in there. They even say that the sleeve may not be seated against the lip completely and there may be room for a tiny amount of movement. That lip looks pretty worthless to me and your picture clearly shows part of it broken off (do you know anything about where the block came from and why?) Once that sleeve starts moving just a little, I doubt that lip would last very long. I bet that lip would reduce the amount of slipped sleeves but it can still happen. Especially if the block cracks first. All speculation of course.

 

makes sense to me.

 

I wonder if this is their product or from Turner? bbolin posted that the long block w/gas flowed head and new oil pump delivered was about $5K. It was delivered in three days after funds cleared. For $500.00 more you get the head done up. That is if you are in this type of budget for a replacement. I know there are options out there state side for less. I just wanted to pose the argument for a long block not much more. I sound like the ultimate 'Turner Engineering' advocate and I have not had to deal w/this yet.

I guess to simplify. Budget will dictate each and everyone's case. You can probably find something that will work right up your alley. Most importantly is the warranty I would think. I don't think anybody likes the thought of dealing w/this but it sounds like it's not going to go away.

 

Budget is usually the most important factor. Sure if you've got $4000+ go out and get you a warrantied block from someone like Turner or Atlantic British, ect. I've just seen a bunch of people who think because they've got a "slipped sleeve" they have no choice but to shell out $4000+. Many times people are quoted $7000+. Do i've looked around for other options. That's why i started this thread. To try to find what other options there are.

 

I had my 2004 Discovery II 4.6L in last February for a head gasket. At that point, it had 99,000 miles. The dealer told me at the time that a couple of my sleeves had slipped about a 1000th of an inch, but that there were no signs of coolant in the cylinders. They recommended a new short block for about $9k! The truck had never overheated, so I asked what would happen if I waited and didn't go with the new block now. He said to keep on eye on the coolant levels and perhaps I could get another 15K or 20K miles out of it.... A long story, short. I've driven it 15K miles since February and can't tell that there is any impending problem.

I'm not really certain what to do, if anything. Whether the sleeves slip is a debate. If the block was cracked and the sleeves did in fact slip, wouldn't I have noticed some impact by now?

If I get to the point of putting in a new short block, what is a reasonable labor charge for the work? What should I expect to pat a mechanic to install a block?

 

So far from what I have read, the liners in 4.6 blocks should not slip? My motor ticks due to a possible slipped liner, this from a shop I sublet my truck to do an oil leak repair. I don't have an overheat or loosing coolant problem. I hope I will see something on the heads themselves when they are removed. I don't want to spend $4k plus but a used motor may not be a good idea either.

 

My biggest take home point from the article:

Dont rip apart your 4.6 motor to find a tick. Let it ride.

Whats to gain?

 

I emailed AB about the short block, and if it had the top hat liners. No reply yet.

My D2 has some noise, that might be considered a tick, when you first start it. It goes away after a few minutes. I always thought it was the exhaust system.

 

Go to a lighter oil and see if it helps.
