Any tips to avoid some very light oil spray after a hard drive that is coming out of my breather. A mechanic friend says it is unavoidable. I like to keep my motor clean. Any thoughts? I thought about putting steel wool up in the breather but I figure it willl just saturate and eventually release oil. Your tips?
are you running stock valve covers? if so, a decent set of new valve covers with the push in oil breathers w/ grommet and oil splash plate underneath is a good way to go. The stock valve covers have a splash plate underneath, but they dont always work well.
I got generic chrome covers with and oil guard inside. It is a push in breather with rubber grommet, maybe I should get a better one like an edelbrock or something
Have you got a new breather lately, and replaced the PCV Valve in the back of the valve cover? You may have a little blow by causing this.
sounds like your common "blow-by"... and if so, it is unavoidable like your mechanic stated earlier unless you have your engine rebuilt. most "blow-by" is caused by fuel entering the oil/crankcase at some point and will eventually come out of the crankcase during ventulation as an oil vapor.... hope this helps
PCV is not emissions. The gases inside engine block needs to be released. A PCV or road draft tube will remove these gases. If not...you will push oil out at the weakest link. In this case the breather...in other cases between the gaskets. See http://en.wikipedia.org/wiki/PCV_valve
Not sure why no pcv or some kind of evacuation system on this. Older cars had the road tube that even sucked vapor out when moving down the road just deposited oil on road, not a good thing. What do you have for a breather system now?
The road draft tube evac system wasn't really a bad thing for the road. Heavy trucks are still using this method for crankcase evac systems. It's really the only choice for supercharged motors, otherwise the gunk from the crankcase gasses end up in the turbo & supercharger vanes
