Road Draft Tube
Do you have to have one? PVC valve?
I am going to have a flathead rebuilt for my truck and the engine currently doesn't have one (its missing). any specific info concerning draft tubes or alternates would be greatly appreciated.
Thanks
Josh

The benefits of the PCV:
Positive, works all the time, not just when you are moving over a certain speed.
No frothy mess dripping on your driveway.
No oily haze around the breather.
You don't have to have one, but the draft tube is designed to pull fumes out of the motor. So, if you don't have one, you have some additional risk of internal sludge/goo buildup, or, wherever he tube attached, a mess there.

I ran a hose from the draft tube to an original ford carb spacer with the pcv attachment. And an inline pcv check valve. It needed a step down barb fitting. It's on a '60 OHV.

You need the PCV valve to regulate this and prevent sucking oil directly in, and not have the connection just be a big vacuum leak. Look at pcv set ups and duplicate one.

Josh - you've kept us in suspense long enough!!! What was the quote? I'm curious, because I've debated building my "spare" block, just to have a spare...

About $3600 which includes new timing gear upgraded cam, valves, align hone (which may not be neccesary),hardened valve inserts, can't rmember everything else but that was pretty much a worst case scenario, so hopefully it would actually end up being a lot less than that, all done and said. oh and it didn't include reassembly (just the valve assembly) I am still going to get a second quote for the same options and see how they compare.
I just need to remove the valves and cam at this point then I will get it in and magnafluxed to make sure its rebuildable. then it may sit a while until I find some $

Wow, that IS a lot...more than I figured, when I found out my block is probably good. You have gone a little further than I would have, but, when I got there, I know I would have gone ahead, and done it right...guess my $1200 rebuilt motor IS a good deal!!
