Re: chocolate mousse in the radiator
Hi Guys, as you can see from the time gap, the B414 has been working fine with Trevors tip re sudsoil, ...until now...
The water went from the top of the rad, I thought maybe a weep over winter so filled her up, started, she ran fine, no bubbles , water moving OK, but overnight the rad emptied again , and I found water in the sump....
I bit the bullet and pulled the head off, but do not understand why the head was still full of water until I broke the seal, and the water-jacket is still full, hinting that the sleeve seals are still OK..
I have examined the gasket and can see no signs of leaking....
what have I missed?

Re: chocolate mousse in the radiator
All motors I have worked on are set up in such a way that the block and head stay full when the radiator hoses are changed
When you pull the water pump off the head will normally drain and half the block or maybe a bit more
Most industrial type motors have drain taps on the block as well, I dont think I have ever seen these on a car engine
I think you will find the radiator wasnt full empty and had only drained enough to drain the top tank and maybe some of the core
Sounds like you have a crook O ring on a sleeve or a crook sleeve to me

Re: chocolate mousse in the radiator
Thanks Paul, what you say makes sense, but what is confusing me is that my manual says after changing the sleeves and seals, fill the block with water to check for leaks...
surely if the block is still full, the sleeves and seals must be OK?
or do they only leak when hot?
also why was the head still full? surely it would have drained through the leaky sleeve/seal or through the head gasket leak?
thanks
Kevin

Re: chocolate mousse in the radiator
they appear to leak often when they have been hot as in used and switched off and it cools down the water seems to find its way thru and quite often you can just start them up and away they run fine and dont get hot or anything
Sometimes they leak once or twice and stop for a bit and you think (hope) it was a one off, but then at the wrong time the fail completely
And no Im not saying it may be a one off I am saying as soon as pull the motor apart and find the problem

Re: chocolate mousse in the radiator
I don't wont to be a kill joy have only found that oil in the water has only ever been a leak through oil cooler or a cracked block as oil pressure is always higher than water pressure ? will be interested to find the outcome

Re: chocolate mousse in the radiator
Just a daft thought, are there any internal core plugs on these engines?
If a LandRover doesn't leak oil, it's run out.

Re: chocolate mousse in the radiator
Thanks guys
Some real good ideas here
Head is off and looks fine, gasket looks fine, so sump off next and prod around the liner seals...
If no seepage can be seen then, I am officially stumped
I will check for any core plugs at the same time
Will let you know what I find
Thanks
Kevin

Re: chocolate mousse in the radiator
I had a '79 Ford 6600 that steamed like a train from the crankcase breather. No trace of water in the oil at all. When we took the rocker cover off there was a small core plug in the center of the head with a pinprick hole in it, changing that stopped the steaming.
Another possibility is from an experience with a Volvo 265. Mousse in the radiator. Oil level perfect and oil sparkly clean. Couldn't fathom it out until I pulled the dipstick out for the trans (auto). Mousse! It turned out the oil cooler for the trans was integrated with the rad and one had breached into the other. So if the rad and oil cooler are one item could be worth a look.

Re: chocolate mousse in the radiator
Hi Paul
Dropped the sump which was full of antifreeze and checked the sleeve bottoms which look dry and fine
Thought I found crack in a liner but it turned out to be a score from a broken piston ring
No core plugs I can see and does not have an oil cooler
Thought it might be a leak from the water pump gasket getting behind timing cover but realised this would have drained the head and block which were full
Can't think of anything to do but rebuild the engine and hope it stays tight
Guess there is always rad weld!
