1965 EGR

Since they didn't start putting an EGR valve into factory truck till the 70's, is there a way to add one to an older vehicle? I'm working on a 1965 F100 240 I6 and it looks like there's an EGR hose, but I'm not too sure. Is there a shop manual that'd be helpful? I have the Ford F-series owner's bible, but so far it's too general.

Thanks in advance!

Welcome to FTE

First EGR valves: 1973.

No factory Ford shop manual or Ford parts catalog for any FoMoCo vehicle will have any info for an EGR valve prior to 1973.

Unless the engine's been swapped, what you are prolly seeing is a neoprene smog valve hose. All these trucks originally came with a PCV valve.

Where is this hose located? EGR valves mount to the carb spacer/EGR plate.

Most of the specific parts are obsolete. Parts will be hard to find if your truck DOES have an EGR valve, since no one will know what vehicle the parts originally came from.

Pictures of the hose would be a big help.

Here's some pics of the hose I'm talking about. I'm also wondering if there's any kind of vacuum running through this hose and what part of the carb it's going back into. Again, I think it's just an exhaust return of some kind.

That's not an egr hose bubba, that's the pcv valve in the valve cover, and the hose goes to vacuum on the intake

Welcome to old trucks.... they are actually more simple than you realize. That's a PCV setup, which stands for Postive Crankcase Ventilation. There's a little valve in the gizmo that slips down in the top of the valve cover. It allow the engine to suck off gases out of the crank case and burn them via the intake manifold (negative pressure).

It was not really intended as a polution fighter - its actually good for the engine as any blow-by gasses tend to be acidic and over time damage the internals of an engine and soil the oil. It should NOT be disabled, as you may find that your dipstick blows out of the block, particularly in an old engine that has a lot of blowby (leaky old rings).

So, enjoy that old six. I got one just like it........

Thanks cdherman for helping! It looks like we have the same truck, though mine is pretty much original. As you can tell I'm just starting to work on it, getting things tuned up. It runs already, but it's old. 1965 F100 240 I6 custom cab long bed. Lovin' it so far!

So if it's a PCV hose, then what of PCV enhancers that I've seen some people use? Should I even bother with it?
