WD smoking out valve cover?

altmodisch · Sep 29, 2013

When working my WD last week all the sudden it starting huffing blue smoke out of the valve cover breather! No noises, no loss of power,, no oil pressure problem it did not get hot! Stop checked every thing. Started it back up same thing pull the oil fill cap no smoke out of it? Runs ok but smoke out the breather, any ideas? Thanks!!

All engines have some blow by but on most due to the PCV valve you never see it. Sounds like the oil breather was clogged up and then the engine got enough back pressure on it to blow the breath open.
