Hi all,
I just picked up a set of old breathers at a swap meet this weekend and a set of FORD rocker covers cheap.
I'm wondering, What were the stock paint colors used on these covers, and were the raised letters painted to stand out? I have 3 pairs, but none have a recognizable paint left on them.
Will the breathers work to take care of the blow by or will I still need the road draft tube?

Installation of a PCV valve and a single breather inlet will be the ticket for reducing any excessive external blowby issues. Using additional breathers will not help in reducing any blowby issues but will help the engine to get rid of any excess crankcase pressure. Adding more breathers just gives blowby additional places to escape from the engine. From a performance standpoint, adding extra breathers is a plus though.

Perfect, thank you Ted! PCV valve and breathers it will be. I was worried about making the road draft tube fit, this helps a lot.

Adding a pvc valve? Doesn't the 60's version have a pvc valve in the valley cover?
addition to post... I only ask that because I thougt mine had one, though given the location I've never actually seen the thing. I would gladly add it with the breathers I have for my rocker covers.

I have five valley covers, three of them have a spot where the road draft tube attached and two of them are blank there. I'm assuming that I will have to drill one of them out and get a plastic PCV valve, then run it to a carb spacer or something. I'm not sure when they started using them...

Search the forum. You can use the valley pan with the hole for a road draft tube. I think somewhere on the forum someone identified the parts numbers for the grommet and PCV. Chuck

Thanks Chuck, I found them. Drilling and tapping the back of the block looks pretty clean, plus when I have enough bread to afford a finned valley cover, I won't have to mess with it again. Here is the previous thread for anyone else. A couple of good solutions http://www.y-blocksforever.com/forums/Topic19139-6-2.aspx
