Un-deleting my CDR (Valve found thanks SteelSoldiers) looking for 1" Neoprene Tubing
I will have to go back and look but I think this is my first real post on this forum. I have been a long time lurker and I even joined SteelSoldiers so I could look at the picture attachments easier. But I try not to post on the internet unless I have a valid question or something to contribute.
Well after 8 years or so I finally pulled the trigger on buying my 1985 CUCV Banks Sidewinder with a 4L80E and electronic trans computer. My second military vehicle I previously had an 406 DOKA UniMog. However my move into the Sierra Nevada mountains made a naturally aspirated diesel tug an impractical option. So I was looking for a turbo charged military truck that could be a daily driver and offroad capable. I spent MANY MANY hours reading these forums and learning as much as I could about these trucks so I would have a pretty good idea of what I was getting into. Just an incredible resource of information this website is. I have a list of project that I plan to complete on my truck to fix the known issues that you folks have diagnosed and created workarounds for. So before I get to my question I wanted to thank you folks for all the time and effort you have put into keeping these old girls running and sharing the information.
My truck is a little bit of a basket case and I bought it non-running on eBay. I don't mind all of that. I enjoy working on my vehicles and working through the problems has forced me to read the GM technical manuals for these engines and become more familiar with my truck. While I was going over my engine examining the modifications I noticed a port was electrically taped off on my Banks air filter. My oil filler tube port was open to atmosphere and 2 ports on the intake were capped off. Red flags went up and I started to dig around the GM 6.2 training manual and read up on the theory and operation of the emissions system and found that my CDR had been deleted. I searched the forums and found an excellent post from jdemaris with crossreference Delco part CV910. Found a great deal and it will be heading my way in 2 days. What I couldn't find are the hose that goes from the oil filler tube to the CDR. That is a discontinued part from GM and I couldn't find any crossrefernces. I found similar shaped parts but without dimensions its nigh on impossible to guess dimensions from a line drawing or picture.
I consider myself pretty good at searching the internet and looking for workarounds but I could not source 1" ID Neoprene tubing anywhere in quantities below 50 or 100 feet. All of the heater hose I could find in the 1"diameter was either EPDM or Silicone which are both nogo for hydrocarbons. I found and industrial supplier for nitrile tubing that could withstand a mild vacuum and again $100 minimum order for 25 feet of hose. I'm not worried about the pre-molded part if I can find an appropriate hose I can either make it semi rigid to prevent kinks or strategically use fittings to route it through my engine. I am really curious if anyone else has run up against this problem and if so how they solved it.
Thanks
