Check to see if there a hose clamp on the rubber stand pipe that feeds the CDR. The rubber stand pipe is very brittle after this many years - trust me I bought a new one because it came apart and I got to dig the pieces out of the valley pan. My only saving grace was my engine was on the stand when I yanking it out of the old valley pan.

Oh I guess I forgot to mention the rubber stand is just pressed in there. It has barbs that give it fricton to hold it in the valley pan.

so just yank hard?

Be careful with that hard yank remember the thing has called that hole home for a long long time. Be gentle man... Little twisting action does wonders but try not to fold it or bend it because it will break. But yeah it's pretty much just yank but again be GENTLE!

ok well what about getting it back in?

R0oster06 · 03-07-2005, 01:53 PM

and does cleaning it make a big differnce or not really?

It will go in easier than it is coming out. You should clean and inspect it, if your going to keep it.

ok well as soon as the rain quits ill give ita shot im on spring break and im fighting the weather i run out when it stops and run back in when it starts. going through a little list of a few things that need to be done with the truck. i still need to adjust the idle on the new pump. 650 in gear right, for an e4od. im just worried about trashing the pedistole for the cdr valve.

i just used an areosale degreaser or how ever you spell it. question though. i ran the truck got her warm shut her down and pulled off the air cleaner and i noticed smoke coming out. is that from the oil or what?

What your seeing is the gasses created inside an internal combustion engine. Nothing to worry about... that is what the CDR is routing back into the intake stream.

Whew good to hear. Thats what i figured just needed to hear it!
