Just got a 86 ford, the trip home was about 15 miles and the truck used a half gallon of oil. Is there something other than rings that will cause this?

 

has it been sitting long any visible bad leaks does it smoke bad check some of these things out first unless you got it cheap bad rings right out of the shoot would suck

 

truck was given to me so i have nothing in it, truck does blow alot of black smoke. I was tring to fix it cheap for a work truck to keep my dodge out of the saw mill thanks for help

 

Black smoke would indicate too much fuel, it would be blue if it was burning to much oil. A bad CDR can increase oil consumption.

 

dont mean to sound dumb but what is a cdr

 

A CDR is a crankcase depression regulator. It's similar to a PCV valve on a gas motor. If your truck is non-turbo, it should be located on your intake, just behind the throat. If it's turbo, it should be on your driver side valve cover. It looks like a tuna can. There will be a small hole on one side, if you can blow air(use your mouth, not a compressor) through into the little hole and it comes out the big hole, then the diaphragm is broken. If it's good, then rinse it out with some gas(not diesel) and reinstall it.

 

also they do not have exhaust valve seals from the factory. i intalled them on mine and i went from using a gallon in 3000 miles to .5 qt in 3000 miles.
