15/30

engine has been rebuilt. crank fine no wear, bores honed new rings, head tested and skimmed , new gaskets all round. checked and rechecked every thing. new release valve for crankcase. it gets warmed up then just spews oil out of breather

oil squirts under pressure

yes cleaned it with petrol . even welded a bigger pipe on the breather exit .

sorry ,do not have the capability to do this. but will say that the vehicle went for a 3 mile drive today and it blew 1/2 a litre of oil out of the breather. if that is any help.

This is not a bit oil splashing . there is pressure behind it .

thank you

inbetween low and high mark on dipstick. about 6-7 litres

Having trouble with a 2.3 diesel. Keeps blowing oil out of the breather . engine has had new rings and the bores honed, the crank has very little wear on it , new pressure relief valve on the oil pump.using 10/40 oil . all new gaskets went into the rebuild. cannot work out what the problem...
