;)Hi,
My son's 44 was burning vast amounts of oil,there was no alternative but to remove the engine.We removed both heads and barrels to find a badly broken oil control ring on the left hand side. Edwin found a local piston guru who perscribed a suitable ring,it necessitated a small amount of machining to widen the groove,job done,engine back in and ready to run. I'm sure that if anyone has a similar problem Edwin could put you in touch with this guy. starider

I'd love to know why problems always seem to be on the l/h cylinde with these. Can't help feeling there must be small some design flaw that could be cured if it was identified....

Hi, Normally if a ring[or rings]break,it's due to a minor siezure[or nipping],perhaps for some reason the L/hd cylinder is not cooled suffiently,or the cylinder is not lubricated enough.I seem to remember when we had problems in the 1970s it was usually the l/hd cylinder. The higher mileage engines always had slightly more wear on that side. We may never know!!!!!!! starider

my engine had failed on this cylinder too... inside the air duct is a piece that I thkn is there to divert air to the carburettor feeding air pipe, maybe this is causing the air not to meet this cylinder as much, also the right hand one seems to have a hole at the bac to let spent air escape whereas the left one doesnt.. when I get my engine rebuilt I may experiment a bit and see which side gets the most air.

one theory I had is rotation of the crank is right to throw oil up the left hand pot but maybe some part of internal casing prevents the same happening to the other side,

If your 44's engine oil is mixed with radiator's water or there is some clots looks in a radiator then its means there is some ting wrong with engine rings due to their weakness.

Absolutely. Not many people know to look out for radiator leakage on the DAF 44. It might also be a problem with the 33 and 46, although we tend not to get too many reports of that.
It's also worth remembering to check the linkage from the clutch pedal, because sometimes, it fails and you don't realise that you are trying to operate the clutch due to the cable chafing against the nearby radiator hose, which in turn can also cause some leakage.
There is so much to look out for, but we quite enjoy the challenges.
Thank you for sharing your thoughts.

Why I think I might have detected a hint of sarcasm there.

Richard, I'm impressed - I thought you said you didn't do technical stuff! ;D
