PCV does side matter
Hey guys
I installed a set of chrome valve covers this weekend. I was going to replace the hove on the passenger sid ewith a breather and leave the PCV valve on the driver side. Th problem is that the breather won't fit under the black box for the heater. Can i just switch sides and put the breather on the driver side and the pcv on the passenger side? Oh yeah its a 77 f-150 with a 400 edel non-egr intake and 1406 carb.
Thanks
David

Either side should work fine as long as you have the baffles in the valve covers. The only thing to worry about might be if you have an excessive amount of oil on top of the heads, under hard acceleration, the oil might pool under the PCV and get sucked into the intake. Not very likely though.

Well i went ahead and tried it but it wouldn't idle the same. It ran worse and when i had driven for a bout 5-10 minutes i opened the hood and the PCV had blown off the passenger side and there was smoke or steam coming out of the hole and the breather. I switched it back with just a paper towel in the passenger side and the pcv in the driver side and it ran better idled better and there was no smoke coming out of the holes when i opened the hood the next time. Why did this happen? Anyone have a suggestion on what i can do with the passenger side instead of a paper towel?
Thanks

dbarracuda I have a 1978 400 stock f150. The pvc is in the drivers side front of the valve cover. Do you have a place on the oppsite cover to put a hose running to either the air cleaner or an air filter? Your engine pulls air in one side and pulls it out the pvc side into the intake manifold where the unburned fuel is consumed. That is my thinkin anyway

Could you run some kind of an elbow in the passenger side to allow clearance for a hose to run to a fitting on the bottom of the air cleaner (inside the filter)?
This would supply filtered air for the crankcase and would recycle any excess blow-by/oil mist that the PCV couldn't handle back through the intake.

David the way I understand it's supposed to work is for air to be pulled inside (passenger's side) and vacume to be applied on the other (driver's side). I think if your getting nasty stuff out of the passenger side cover then something else ain't right? The pvc should make your truck run better not worse too.
