Default PCV systems on the smallblocks

I grabbed some parts off a 63 galaxie with a 260 that had the PCV on the intake,yesterday I was in a local old junkyard gathering the rest of the parts to make the 302 look older and found that most 64 and up had the PCV in the pass side valve cover and then I found a 65 Fairlane that had a road draft tube attached to the pass valve cover.I thought all motors had to have a PCV around 62 or 63 so was 65 the last year for a road draft tube.

As for CCV (Crankcase Ventilation), it depended on the area of the country whether a car/light truck had to have either. A car in CA or NY would require PCV where a state such as WY or MT might not.

FOMOCO assembled them as cheaply as possible to meet area emission law(s).

Yes, where it was to be sold new had a great deal to do with original equipment. Being from Minnesota, all the cars I saw had a battery that was a big grunt to lift, and a radiator the size of a big heater core. While scrounging a junk yard while in Oklahoma in the mid sixties, I found radiators big enough to cool a truck, and a battery that I could throw to the county line. Later, while working on the motor line at Ford, I found that alternator size, fan size, and other things that were different from place to place.

I can't find any pictures or evidence of any regular US production ford V8 using road draft tubes after '61, and certainly not in '65. What was found on that Fairlane was most likely someone's cobble job ventilation system.

I have a 292 from a 62 galaxie that has a road draft tube and figured that was about the last year,I grabbed all the PCV parts from a 292 in a 63 or 64 truck in a junkyard.Maybe the 65 had a earlier motor but I think the 62 and I know the 63 small blocks had the ventilation system hooked to the rear of the intake,the 65 had the tube hooked to the valve cover where a PCV would go and was a factory part.

I have a friend who bought a 1965 Comet with an A code 289 4bbl brand new. Still has the car and the road draft tube that came with it. The road draft tube was attached to the right side valve cover. This car was delivered in Long Island, NY. So the answer is, yes some 1965 Fords came with a road draft crankcase ventilation system.

What he found is OEM (actually need good photo). Whether the car got either system depended entirely on the ENGINE CALIBRATION.

The road draft tube (and PCV valve were moved to the rocker cover in later production as it was a more efficient design. The rocker cover road draft will/should have the oil fill/ventilation cat (open system) on the left rocker cover.

Below is an early production MUST with road draft provision. Both road draft and PCV used the same intake for the period.

OK, you've convinced me. Just real odd Ford would switch to a pcv on the soon-to-be out of production 292" Y-block, along with the FE (and maybe others) in '61/'62, but would use the road draft on a brand new engine family all the way to '65.

I just wish I could post more info but am waiting for printer ink.

FORD actually first offered PCV in the 1960 model year, a model year earlier than the CA requirement. As for the 292, it had to comply with differing area emission law(s) so it was fitted with PCV. That is why it is so confusing as the engines were built/calibrated for where the vehicle was to be sold.

Either FORD had to bring the 292 into compliance or was not allowed to sell the 292 equipped vehicle in CA for instance.

You are a tech guy.

I always loved SLEEPERS. Open the hood and show the guys (usual suspect chebbie and NoPar owners) your antique looking install, they laugh and put their money up and you drive to the bank.

...sigh...

That PCV system I got from the 63 260 bolts where this road draft tube attaches.

Correct. the intake was cast to accept either system.

Is this engine a 2V or 4V?

I would show you a photo of a period SHELBY TIGER ALUM 4V intake but your heart may not be able to take it...

The 5.0 EFI had the PCV in about the same place on the manifold.
