Wondering what could cause oil coming out of blowby tube, could collapsed air intake line cause it or clogged air filter?

    High oil level worn rings head gasket Is it a turbo? did it blow oil from new or has this just started? How much oil? a mist? a drip? a steady drip?

    What is It in, and what are the nornal operating conditions, I have seen a few that just idled most of the time do this. Skytrak telehandler comes to mind. Never worked hard with a lot of idle time setting roof sheathing. they ran the rats out of it a bit now and then and it did clear up the slobbering problems.
