[rustypete]

help needed here lads did the head up ground the valves left it on the bench upside down put tissue under it poured diesel on top of valves left for 12hrs no diesel wept past valves or the seats fitted head on block all new gaskets including new valve stem seals the thing is it is blowing oil out of exhaust quite a bit but strange to me there is no BACK PRESSURE pull out the dipstick jest next to nothing put finger on it not even oily it is oil that is coming out not diesel new diesel pump and injectors will be glad of any help thanks rustypete PS fordson major 1957

it’s not the turbo is it If fitted? Could you of blanked or restricted the oil return hose/passage?

Manifold off and see which cylinder is at fault?

 

[rustypete]

no turbo fordson major

Needs a day's hard work

Is there a chance it is still blowing oil out that found its way into the exhaust while the head gasket was blown? We had an exhaust that was properly sooted up and on a tractor that doesn't usually do much hard work, when it gets put on the slurry pump it still liberates crap several months after a new head gasket.

What oil have you used? Could the bores have glazed? I've had this problem with a rebuilt MF35, the conclusion of the mechanics brains trust is that modern oil is 'too good' and it needs an older spec oil and some hard work.......

Give it some work and might soon clear up.

Stick it on a rotavator for a few hours

 

[rustypete]

will keep in touch and will reply once I try a few things that all you lads said thanks for all feedback rustypete

 

[startinghandle]

Is it smoking bad?
What oil are you using?

 

[Rs chunk]

It’s either needing a good roasting on a rotavator as mentioned or what was your valve guides like? Wear in them can cause oil out exhaust

not smoking bad a tall it is on a log splitter engine oil is for a jd6165 engine thin looking

i think this could be the trouble will get back to you about valve guides thanks

 

[Pennine Ploughing]

never know valve guides give that much bother ,
there might be no back pressure as it draws air into air cleaner pipe from sump as a breather,
it will be glazed bores, log splitter will not help,
give it a good thrashing on a flurry whisk, or something for a few hours

isnt it straight 30 in the engine on the major?
if the oil is for a new jd its way too thin and too many detergents in it

there could be your problem, the engine needs basic oil. and some hard work, log splitters can kill an engine, revs too low and no load on the engine. seen the problem on a bale wrapper tractor.

I use 20:50 Classic oil in all my old tat and never have a problem, even match ploughing (where it's not really working hard at all) Have also found new rings seem to bed in quicker. Used some 15:40 in one tractor and it seemed to take forever for the rings to bed in.
When I used to race we ran the newly rebuilt engines up on the dyno with cheap old oil in them, any semi synthetic from new and the rings never seemed to bed properly, the chap who ran them up even used to put some brasso in on the odd occasion to help the bedding in process.

running in oil

jest to let you lads that replyed to my problem with fordson major I am waiting for a dyno to arrive but could be a while but will keep you informed thanks again rustypete

Log splitter use will cause this. Its bore glazing due to the light load, even happens to tractors used solely in ploughing matches, same reason. It needs a weeks hard work, and that needs to be every few months. To bed in new liners you need a load of not less than 80% full load, you need something similar.Using a running in oil will help.
