I have decided to install a PCV on my 1955 F100 239 cubic inch engine. Neighbors and friends don't appreciate a few oil drops left in their driveways these days. I have to park it over a piece of carboard myself to keep the garage floor clean. I need to find out which valley pans, that already have the hole and baffle. will fit my 239. I believe that the T-Bird valley pan should fit, but am looking for for what you'll have done so I can start looking for one. The T-Pot I can find online but want to make sure I get the right valley pan. I will also take any advice or look-outs as I start this project.
Thanks, Mike

 

I converted a old FE from draft tube to PCV and all I did was block of the road draft tube with a flat piece of aluminum where it attached to the intake, put a breather cap in the front of one valve cover and the PCV valve in the back of the other valve cover, also It had a vent cap on the oil fill location, I also blocked that off to make the PCV pull air from the front of one bank to the back of the other and connect to a vacuum source, been that way for 20K miles with no problems

 

On my Camaro I eliminated the PCV and run the valve cover vents to a catch can. I don't know the aet up on your engine and how it works, but maybe venting to a catch can is an option as well.

 

Well, it is not only the drips (excessive crankcase pressure - blown gaskets/seals) that will bite you but the crankcase is not getting ventilated completely with the road draft system.

Pans to look for -

1955/57 BIRD ($$$)
1960/62 FORD 292
1960/64 FORD TRUCK 292

2V or 4V?

 

Thanks for your responses. I have read about different methods like Ishort mentioned but wanted to replicate the early PCV system using a valley pan set up for it. I will need to get a riser for the carburetor with a vacuum port as well. Its the original engine with the 2 barrel Holley 94. When I up-graded my brakes with a power booster I used the vacuum port on the intake manifold for that.

Thanks for verifying the valley pan KULTULZ.

 

Is the valley pan on my 1955 239 the same as the valley pan on 55 T-Bird? I called and they weren’t sure but I was assuming it was. Just want to double check before I send it to them.

 

Not the same. The PASS CAR uses the older road draft style found on the FL crankcase skirt and the BIRD uses a road draft tube coming out of the back of the valley cover.

 

Ok so if I have them modify my valley pan they would just need to add the baffling and the opening for the PCV, Is that right?

 

You mean the CASCO modification?

I have never seen one of theirs modified. Maybe talk with them as to appearing and functioning as correct.

You can also use a cover from a 1960-62 FORD CAR or TRUCK..

 

Yes CASCO. I will have to see if they have someone else I can talk to. My preference would be to have mine modified if it works. The one thing the person I talked to said is that it should be the same as the 272. Hopefully I can send some pictures and provide them with as much detailed information as I can so they can determine if the modification will work.

 

Also with their modifications you don’t need the tee pot. Would you need that with the 60-62?

 

Well here's the thing ...

That adapter acts as a baffle (although it is not baffled internally). It leads to a hard pipe than loops back down to the PCV valve install and acts as a cooling tube to help separate oil mists from the intake air before hitting the valve and fouling it and the intake charge.

The tray under the pan is not designed as a baffle. Its purpose is as a splash shield to prevent direct ingestion of the DIST cam drive throwing oil.

You want the PCV fumes to be drawn directly into the carb spacer so as any mists/fumes are distributed evenly though-out the cylinders.

Here is a 1960/ PCV install -


There is also a baffle about midway on the underside of the pan. This diverts air flow being drawn in from the oil filler cap to ventilate the valve-train.

 

The later 1960/62 valley pan has an oil filler tube that is slightly bent (not straight as earlier pans) to clear the coolant expansion tank use on the PASS CAR.

 

Thanks for that illustration. I got it now and can look into this further. I have never done this before so it has been very beneficial and educational.

 

This method was the latest engineering at the time but it worked (the 2V was plumbed differently).

The trouble will be finding all the take-off parts as not all applications had PCV, as most had road draft all depending on where the car/truck was sold.

If you plumb as thus - ... the system is going to draw excess fumes/mist into the intake tract as there is no baffling/filtering and that amount will be determined by the amount of blow-by and calibration of valve chosen.

But the PCV SYSTEM will propoerly ventilate the crankcase and lessen the chance of blown gaskets/seals.
