Jeff,

Do you have a small hose running from the valve cover to the spark arrestor?
If so, check the hose and connections to ensure they are clear of any
restrictions. While at it, clean the spark arrestor. They can get a little
gummed up over time.

AFAIK this was the sloe means of crankcase ventilation on my old Mercruiser
260.

I noticed recently some smoke coming from my starboard engine. I took
off
the valve covers and noticed a light brown milky substance on the

of the covers and around some of the lifters. However the oil on the
dipstick looks good. I have 2 Volvo penta 4.3gi 1997. no problems on the
port engine.
Does anyone have any ideas as to what this is? Blown Head Gasket?
Thanks

Jeff, when you say you saw some smoke coming from the engine, do you
mean through the exhaust, or do you mean when looking at the engine,
smoke was rising from somewhere? If so, was it in the area of the valve
cover in question? What color was the smoke? Was it truly smoke or
water vapor?
