CDR valve ?

[Alwaysreadyrob]

Hello again fellow oil burners !
Today i called my local NAPA and I was able to stump them on a question, I just asked if they had a replacement CDR Valve... now these boys that run this place have been around but they never heard of a CDR Valve for the 6.9 7.3 Diesel Trucks.
Mine is the Stock 7.3 with the turbo , it was manufactured in 93 but sold as a 94, the 8th character in the VIN is a K.
Any ideas where to get a new one ?

Just got one on Amazon, thanks for the quick responses.
What a great support group we have here. So if mine is grey like the engine does that meannit could be the original ?
I just think it needed replacing after all the truck is a 94 with 306570 miles on er.

It could very well be the original one. The other possibility is that somebody replaced it and painted it to match the engine.

I remember about 7 years ago, these CDR valves were very hard to come by. Glad to see they are more available nowadays

I just ordered a CDR and the valve groomet from a third party seller on Amazon. Some outfits on there will sell them together as a package, but a couple $$ can be saved by buying them separate... even from the same sellers on there. There wasn't any value in the extra value meal in this scenario.

Having a spare is not a bad idea. They don't go bad sitting on your shelf. I'm thinking Navistar will have these. They are the designers of this engine.

I did buy one on Amazon , figured on changing the grommets also so i did get them seperate. Either mine was painted grey like the engine or its the original one. Truck has like 330600 miles on er and i bought it in 2011 at 168,000

Almost on topic: how much oil should be inside the CDR valve if it's working right? Any downside to just doing away with the CDR and putting in a downpipe, other than the smell?

what are the symptoms when these go bad?

I hear a Blown Head Gasket !

 

[Oledirtypearl86]

If they plug your internal pressures like in the crankcase and valve covers get to high and you risk blowing a gasket and leaking oil all over not sure about the head gasket though if it sticks open I'd imaginelots of blow by being pumped in the intake resulting in smoking

I was wondering myself yesterday. I popped my air cleaner off as soon as I got home and noticed a little smoke/steam coming from the intake. Looks like oil buildup on the mesh inlet screen. I'm just running a paper filter so it's not filter oil.

valve cover leaks, oil pan leaks . When I replaced mine, which looked like it was the original at 228K I had driver/passenger valve cover leaks and small oil pan gasket leak. I replaced the CDR, driver valve cover stopped leaking and I re torque it. Passenger leaked less, so i replace gasket and torque it. Oil pan appear to stop so I torque it. To give you an idea on the condition the CDR and grommet condition. The rubber grommet was like black ABS. I had to break chunks of it off to get it all out. I got the really small stuff out later after I replaced the valley pan and IP pump.
