i have a 92 f250 with a 7.3 and in the last 1000 miles my truck went thru almost 2 gal of oil it isnt leaking out and it dosnt blow a big cloud of blue smoke it only has 150000 miles on it there is no oil in the coolant is my motor junk?

 

Have you serviced the CDR recently?

Motor oil is just more fuel for the engine.

 

very true, and mine is now almost smoke free after the cdr service(i may just replace it all), way more friendly to those behind me hahaha

 

i will have to give that a try ill look it up on here mine dose blow alot of black smoke when i am driving at anything over half throttle

 

there is a difference between black blue and white. If you are over half throttle and you see black smoke, i would say the ip is turned up.

 

Sorry for sounding like a noob here but what is the CDR exactly??

 

the CDR is the Crankcase Depression Regulator.

"The CDR valve is responsible for controlling the pressure/vacuum in the engine crankcase, and seperating the oil mist from the air and returning the oil to the crankcase."

 

How do you clean/service the CDR?

 

Pull it off, Soak it in gas, DO NOT BLOW it out with air! That will rupture the diaphram.

If you get chunks of rubber out of it, toss and replace.

Take off the filter housing, look right behind the intake opening. It looks like a Little can about four inches across and three inches thick.
