Hi all,
My engine has 50 hours SMOH, and I changed the oil last night and noticed that there is some blow-by on the intake pipes up by cylinders #2 and #4. I think this is pretty recent, as I have had the cowls off before the change.. within the last 10 hours or so and I didn't notice the accumulation before. There doesn't seem to be a lot of accumulation but...its there.
I am getting about 6 hours to a quart right now on the engine, and maybe this blow-by is a signal. I have attached a pic of the intake pipe on #4. Its seems to be originating at the flange to the cylinder....I find it hard to believe that the gasket is gone already.
Should I be worried? The bolt torques on the flange seemed to be OK.
picture of intake pipe on #4 is here:
Thanks for any hints
