landrover freelander oil in water

DMECH,

I'm not sure what this means "1 burnt valve ex.head us flat gasket looks good". Some punctuation would be good.

However, I strongly suspect a cracked cylinder bore if the head gasket was not burnt or blown AND the head has been checked for flatness against a plate with engineers blue or with a good straight edge.

As it's an aluminium block, does it have "wet" cylinder liners or "dry" cyl liners?
Aluminum blocks have always scared me.

sorry bilbo should read found 1 burnt ex. valve head is flat cant see any relation to burnt valve and oil in water. eng. has wet sleeves however i dont think it is any thing to do with sleeves

I am not familar with this engine does it have an oil cooler on the side of the block ? if it is not that I would suspect the head before the block...

I had this problem in two Nissan (petrol) motors I have had over the years.

Both had alloy heads and started to 'pee' oil into the water/coolant, slowly at first, then in copious amounts.

The were both cracked, with the said cracks going through the oil gallery.

One was fixed by welding and a welding attempt on the other failed due to the position of the crack.

It was right across the head between No. 2 & No. 3 cylinder and full depth of the oil gallery. Had to throw it out and re condition a used one which I have on now.
The cause of this one was my own doing from way too much R&Díng in the way of machining to tweak up the 'power'.

No idea why the other one cracked, however suspect a cooking.

The other thing was that the only test that revealed the said cracks was a compressed air test in the engineering shop, where they plated off all ports, submerged the whole head, and pressured up quite high before the cracks became apparent. Quite amazing to watch, as I thought they would show fairly easily.

Anyway there's two bobs worth of useless experience/information for you to think about

hi
There has been a lot of bad press regarding the cylinder head on freelanders over here recently so you may have the same problem click on the link for more info.Hope this helps.

This model engine gives trouble, usually around the head gasket area. My suggestion is to see someone who is an expert on these engines as there may be a crack in the block somewhere.

Maybe a Landrover dealer can help but their fix would be a new engine - and it may come to that from what I have heard on various Freelander forums that I subscribe to.

We have a V6 Freelander, still not the best of engines but a bit more reliable than the 1.8 one. Pity about the rest of the vehicle.

Freelander engines are well known to drop the liners into the block.
Because the liners are steel and the block is alloy, the harder liners work theyr way into the block. Get a specialist on it to measure the liner heights. There is also a new headgasket available and you have to change the thermostat setup. Land Rover recommends to remove the existing thermostat and fit a new top radiator hose with inbuild thermostat to increase the coolant flow in the head during warm up.
I never came across a cracked head or oil gallery on a Freelander. The bad news are;
If the liners are too low, the engine needs to be replaced!!

Hope this helps
