Hi, is this what I meant to post above, I had quoted COORS and I didn't realize it would include the URL and override the text (I have since edited that). I am quoting myself now because I would like to invite anyone who has had experience with Turner Engineering UK's remanufactured blocks or with installation of their ductile flanged sleeves to share their knowledge. Thank you.

 

LR thermostats are defective; replace your thermostat with an after market. UK engineering is investigating the problem and it is believed there will be an official announcement shortly, Note; this is my determination and is only my opinion/theory at this time.

 

If there is a crack in the block or a slipped sleeve would it leak coolant? I am asking as a novice.

 

Slipped liner = no, the liners are not wet.
Cracked block will depend where the crack is.

 

See Bundu.

 

The sleeves are not flanged. The sleeves are not wet either, meaning no coolant comes near the sleeves. You can remove a sleeve and the block will not leak coolant. If you have a crack in the block that breaks the seal of the water jacket then it will leak. I had a slipped liner on my 2003, I took the block to a machine shop and for ***** and giggles we pulled the liner and above statements are based on my observations, not on hearsay or guess work. The liner is a simple tube pressed into a cylinder, there is a lip at the bottom of the cylinder to keep the liner from slipping down, but nothing at the top to stop it from slipping up. In my case the liner worked loose and slipped up through the firing ring and into the head.

 

Hi Bundu. if what you say is correct "no coolant comes near the sleeve" how is it on the previous page the You Tube video shows to the contrary. That sleeve slipped and appears to be 'wet". The mechanic (which I believe knows what he is talking about) doesn't say anything about the block being cracked. It looks like coolant does come near the sleeve. Maybe the block is cracked also??? That video was what gave me the impression the sleeves are wet. Also curious; if the sleeve lip is at the bottom of the cylinder how is it possible for the sleeve to slip upwards and into the head?

 

The sleeve may not move down but if it comes loose it can easily move up through the head gasket and into the soft aluminum head. The piston moving up and down will slam the sleeve into the head and you will notice a tapping that gets louder and louder the longer it's left untouched.

 

Sold it today......That thing is not my problem anymore thank god.

 

The leak is from a crack in the block behind the sleeve, they are known to crack from the head bolts putting stress on the aluminum. The top of the liners resemble a chisel point, once they work loose they cut their way through the hg and into the head.
These photos should clarify what can happen. There was 1/8 movement up and the liner had worked its way 1/8 down, so a combined 1/4 movement - this thing sounded like a jack hammer.
