    Next thing we’re gonna hear is that the number 4 injector failure caused the oil consumption due to the tip blowing off the injector and scoring # 4 cylinder. Just a wild guess.

    Well checked the oil this morning and is still on the full mark, went through 402 litres of fuel yesterday, not sure why this engine is doing this, it seems just all of a sudden it starts going through oil then stops, is this how a new engine breaks in? we will keep watching, not sure what is next, but with the bad experience we had have with the 140m's I am superstitious, i'm thinking this engine will torture us.

    Don't give them the daily usage figures, just give them the gallons of oil / gallons fuel figure over weeks or a month and hopefully you can get satisfaction that way....

    Average the fuel vs oil added figures over a week/month if it helps to smooth out the "bumps in the road" that you might see in the daily data.

    Wow! 3L in one shift you'd think you'd be seeing a puff of blue out the exhaust now and then.

    You do see exhaust smoke when going from forward into reverse and back again but never noticed any blue smoke or smelled a hint of oil burning from the exhaust fumes.

    Nige, could the inconsistency of usage possibly indicate a crankcase ventilation problem that comes and goes?

    I'm struggling with the idea that there's excessive oil going past the piston rings one day and not the next.

    I have seen an issue like that with valve guides. Working a lot of hills can leave oil sitting on top of the head at times and slows down the drain back to the crankcase. Does this machine have a positive crankcase ventilation and a filter?

    Well here's a update, as for the burning oil issue the engine seems to take spells in oil usage good for about 500L of fuel than drop 3 Litres of oil on the next 250L of fuel used, currently our machine is out off service with our next issue, blown manifold gasket, turned every thing black in the engine compartment, partner did not notice it where he was out on shift at night ice blading, wasn't till he got back to the shop that he noticed all the panels were black,... guy's this is only the start of a long and tortures road ahead with this new engine.
