As above.... k74 145000 miles Doesn't miss a beat ( most of the time !)Uses 1 litre oil per 5000 miles. The temp gauge stays rock steady.The exhaust is very clear, passed the mot easy. As you know i'm just setting the valve clearances and have cleaned and checked the rocker cover breather pipe which is completely clear. Recently when giving the truck on a good run the dip stick is out and traces of oil splatter . Thoughts? beginning of problems ahead? Would i get away with less oil in (6.5 litres) and drive it more gently or best to nip it in the bud.... Nik

Is there a crankcase breather tube thats blocked??

get a new O ring on the dip stick

I'll check that....Where does the crankcase ventilate to?....

rocker cover to air intake

might that be blocked and stopping the c.case breathing and hence pressurising the sump ? If I blow down that tube should it be free?

its possible
I have never seen it happen

sorry guys a bit off track but at my age a spurty dipstick means something totally different
