in THE MAIN WALL
I've been a tech for a short while. When you are on a service call that has alot of sludge in the oil line is it better to blow out the oil line with a co 2 cartridege or push/ pull the line and take out alot of the gunk until the oil runs clean. Thanks.

    I'm for push pull pump

    You can feel what's going on, and the risk of blowing open a line or fitting is less.

    I never want to see another return line underground with a leak in it. That's a pretty bad feeling in the stomach.

    Pop Relief

    I agree with Noel with his concern on oil line rupture . For that reason we stopped using the CO2 for a while and used the push pull only . We found it works fine for most of the oil lines but had problems with others . We went back to the CO2 but with a pop relief on the gun to release pressure over 100# . Have not had a (reported) problem in maybe seven or so years...

    Now the best way I found to clean a line is blow it back with 2 cartrages then suck it back with the push pull until the oil looks clean. Or you can push it back first then pull until clean . Don't just hook it up with out the clean flush , it would just fowl the nozzle . Which since were are on the subjuct . After a filter , strainer or oil supply clean up run the nozzle line into a can untill the oil looks cleans . This practice would save alot of call backs....

    P.S. If you come across a old job buried tank with iron pipe comming through the wall as oil lines .Don't blow or push it back to the tank. Only pull the oil .It may have a foot valve and pushing back will jam them up . You will be there for hours trying to push and pull to free the @&#$ up !

    Happy Motoring :)

    They don't ....

    Call them blowout guns cause they clear the lines! Avoid a CO2 charge at ALL times. Sids'Westwood and I believe Firomatic sell a great pull/push pump and if it doesn't clear with it, replace the line and/or the tank.
    By using the "blowout charge" your opening yourself up to a whole lot of what ifs, and whys.Insurance companies aren't too kean on letting oil spills slip by now-a-days! Chris

    I use

    I've used both on some occasions, but usually just the CO2 charge.

    oil lines

    When you disturb the sludge in an oil line ( Co2 or push pull pump) you open the possibility of an oil line leak. In a perfect world,restricted or plugged oil lines would be replaced.We could also replace the oil tank and fill with clean oil while we are at it. Too Bad we don't live in a perfect world!
