Update: Hi Guys, got head back on and built up( why does the manual give you a head torquing sequence, when you cant access 3 bolts when the valve gear is on? and why tell you to set valve clearances to 20 thou "hot" when you are building up a cold engine!) anyway, I found an old gouge on ...

Hi Guys, just found a potential answer... put the old head gasket on the head and noticed by the carbon marks that it was not aligned true, the ferrule from one cut-out was actually in a waterway.... still confused why it should take over 12 years to manifest as a problem, but guess the low use of t...

Thanks Guys, good points you make... currently , head and sump are off and one piston is out waiting new rings, frankly, if I could get hold of the right puller, I would change all the liners as a matter of course, but I dont have one of those and getting the liners out is a swine!, pressure testing...

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 pu...

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

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...

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...

Hi Trevor, just wanted to let you know I tried the sudsoil tip and it worked!

water in rad is white and slightly oily, mousse gone, no water in sump oil and tractor running well


many thanks!

Thanks Trevor!, just getting prepared for thunderstorms and torrential rain here, does not look like I will get a chance to do much on the engine next few days, also my MGBGT has sprung a leak, and I go to the pub in that so it comes first!

all the best.

Thanks Trevor that is really helpful! the tractor seems to be running OK with the oil in the water, so if I can keep it going that way I am content. I never heard of oil for radiators or emulsifiers, but have heard of baking soda being used to flush out these rads in the past, but it seems a bit har...
