Brand New CDR Valve From Ford, Pictures And Part #'s Here

[Still Strokin]

While building my truck, I have came across alot of BS on forums, un true information, and wrong information... I've read countless times that cdr valves are not available, and that "F250 and F350 rear leaf springs are the same its just the 2" and 4" block thats the difference" ... First off... They ARE different... The spring rate is different.... Whether you have a 4 leaf or 5 leaf pack,,, The part numbers are different... If you want a 1 ton, you have to change the rear leafs also.... Second of all , the valve is still available from ford, here is the picture and part #'s, so no one else has to go through the headache I went through

For Grins and Giggles, how much was the CDR from Ford? Was it a special order part? Thank you for your time.

Here is a Ebay Link if someone needs one, ive read that they are cheaper thru IH dealers. No relation to that ebay auction.

Damn, I wish that auction was going on 2 weeks ago .

So the International part number is 1805319C1 for those who can find an International Harvester dealer.

That's the Way it Goes, Right? Do these Valves go bad very often? I thought I had read that they where fairly bullet proof with Minimal Maintenance.

Become friends with the Ford parts guy!

I bought mine for my '91 N/A 7.3 in August. I have dealt with this same parts man for over 25 years and he gives me a break once in a while.

I bought all three pieces:
E8TZ-6A892-A RETAINER (rubber tube from valley pan to CDR)
E3TZ-6A892-A GASKET (CDR to intake seal)
E3TZ-6A665-A ADAPTER (CDR)

With sales tax, the total was $60.06 and I had the stuff by 11AM the next day.

Yea I wondered too if they went bad, it doesn't look like much more than a 1 way pcv valve to me, but my turbo kit, and intercooler is brand new going on a spotless low mileage truck with thousands of unneeded dollars dumped into it so why shortcut now lol

I bought a new one because my old one flowed the same in either direction..... but so does the new one.

I was going to hack my old one apart to see how it works, but it's still in great condition.
They might try to close if the air filter becomes badly blocked - which would regulate the crankcase air / oil vapor being drawn into the intake causing a "runaway".
Other than that, I think they're just along for the ride.

These cdr valves do fail. Ford recommends they be changed at certain intervals to but I have forgotten what that is. The purpose of these valves is to shut off the suction from the crankcase. Our engines can run on the oil vapor from the crankcase easily. If the air flow is high enough the valve sucks closed and the vacuum created drawing the air out of the crankcase stops. It also stops the engine runaway issue if we start sucking the oil vapor bad enough. I'm not saying the oil vapor that is normally sucked thru these valves is enough to cause a runaway either. This cdr works when the air filter or the air going into the intake manifold gets blocked off. Then the engine will eat its own oil and vapor. If our engines start eating themselves only dumping the clutch in high gear will kill the engine. An auto trans is sol for stopping a runaway.

I just got a CDR ordered from Bob Utter Ford in Sherman, Tx. - $54.39 plus shipping. They seem to have better discounts on the parts than most other dealers do.

Bob Utter was known as the Ford parts online store for many years. I was buying lots from him back in 2006.
