changing the oil today as part of the standard spring maintenance and the crank case oil did not drain very well unless I had the oil fill cap off. I could hear air sucking past the oil fill cap as I was lifting it off.....then once I had the cap off, the oil drained out quickly as expected.
after changing the oil filter and replacing the oil, I started it and did feel some blow by coming out of the oil fill cap.
My first thought was a mud dobber plugged the breather line but I saw on L5240, the valve cover breather line goes back into the intake between the turbo and air filter. there is an metal mesh screen under that breather line...is it possible its clogged causing this? I don't think building and holding crank case pressure is normal for this engine.
any thoughts?
