Oil in pulse line, 582 Blue Head

    With this info the only two seals that can be the problem is the rv shaft seal on the carb side or the inner crank seal.I have seen where the crank seal takes about 5 to 10 hours to do its job.Although not common,it does happen.If the oil seal on the rv shaft on the water pump side goes bad you will see oil in the rv bottle first,then the consumption begins.I suspect this problem will "go away" with operation.Your EGT's show that the leak isn't bad at all.

    Hi Shayne
    Thanks again for your thoughts and insight.
    I will keep an eye on things and see if anything changes.
    I'll post again after a few more flying hours, good or bad.

    Interesting comment on oil pump failures. After ten years of overhauling Rotax two strokes I have not had one in the shop for a failed oil pump.

    Hey Clyde
    I did not mean to say the oil pump failed, I was refering to the oil injection system or some of it compnents failed thus causing engines to seize up. Again, I am just repeating what I was told by my engine guy. If I mix the gas and oil, it is one less thing to go wrong. I did have a friend whose oil injection system did not supply his engine with enough oil and it did fail.
    Sorry for any confusion.

    Hi Shayne
    I have been flying a few more hours (5) and the oil consumption has gone down to what I think is acceptable. The level has only dropped abot 1/16 of an inch. That amounts to about 3 tablespoons of oil. I can live with that. Perhaps as you said before, it it just taking a few more hours for the seals to work coreectly.
    Thanks again
    Doug
