Title: help required please...engine problems Post by: surf monkey on November 29, 2009, 22:21:26 pm My sons `72 1300tp recently broke a ring...at the time he ran out of petrol, managed to limp into a garage...phoned me and said it wouldn`t start...i shot over to the garage and he`d flooded it...got it started and he went to pull away , lost power...i lifted the lid and there was oil everywhere, it was coming out of the dipstick tube...i pretty much new it was ring so i got it stripped down and it was #3 barrell....replaced all the rings, gave the engine a really good clean inside and out...put it back in, rebuilt the carb and replaced everything...at first we had trouble firing it up, timing issues but we got round those and it fires ok and sounds quite good.... but...i noticed as it warmed up a lot of blue smoke coming out of the exhaust on the left hand side as you look at it, 3 and 4, and black `water` started dripping quite badly from the exhaust and the joint from the heat exchanger to the exhaust...any ideas would be greatfully received

Has a needle valve stuck, flooding the engine? If that is the case, then you will suffer from bore wash, removing all oil from cylinder walls and can wipe out a new set of rings in just minutes (I know - it took 10 minutes on a dyno once...). Or maybe the broken ring damaged the cylinder? Did you 'glaze bust' (hone) the cylinders or just throw in new rings? New rings will struggle to bed in to glazed cylinders. Just my 2c...
