Hi Guys. Hoping for some info from the "better informed" on how the old ventilator tubes functioned on the Flat Head 6 (Dodge)? My engine was rebuilt (everything done) a little over 10 year ago. It is in a show car that maybe has 30 miles on it since built.. Well.. going to change that and start driving it (tired of looking at it sit!) Anyway.. fired it up.. and whilst idling there was a fair amount of RAW (unburnt) oil exiting the crankcase ventilator tube. I seem to recall this always having a slight drip from time to time.. But this was a decent amount exiting. Question: Is this normal for a car that had not been ran for a couple of years or do I have an issue that I need to address? oil pressure has always been very high on this engine.. in the 70 PSI range according to the original gauge. Anyway.. appreciate any guidance with this. Thanks
There should be some type of mesh filter somewhere in the road draft tube system. It is there to catch oil and allow it back into the crankcase. It is normal for a drop of oil to be on the road draft tube. You really need to drive it and see if the crankcase loses any substantial amout of oil to see if you have a problem.
No, it's not normal. Maybe there's supposed to be a baffle or screen where the road draft tube joins the block that's missing?
I thought ALL engines were designed to drip a lot.... always figured that's how they got the oil to preserve the center of road lanes 'back in the day'!
