2 pcv’s??

[Dkfw03]

Why would I have 2 pcv’s on my boat? I just bought the boat and knew that it had issues... I took it to the lake and drove around for about an hour and it was running great until I noticed some smoke coming from the engine compartment. I looked in and there was quite a bit of oil on the motor. And I noticed it had pcv valves on both valve covers. Could this be the reason that it is spraying oil??

They are not PCVs, just crankcase vent hoses.... There should route up to the flame arrestor. Proper PCVs route to the intake manifold....

The excess oil may be because of blow-by from the cylinders.

Then 'somebody' needs kicking. How are they hosed up? Do you have a serial number for that engine?

You need to have made 3 posts before you can load pictures (it's supposed to be a spam deterrent :noidea. The other way is to load your pictures to a sharing site (or the webpage provided by your ISP) and link them here.

Engine serial number would help to ensure but I believe this system is designed for one PCV and one breather....Item numbers 23, 24, 25, http://www.mercruiserparts.com/bam/subassembly/31490/9021/100
