Engine/Transmission (1994 - 1998) Overflow Valve Replacement

[drrhoades]

When replacing the overflow valve should the threads be coated in anything, i. e. neverseize or thread tape? Also when the overflow valve is taken off will any fuel leak out or is the level below the valve when the engine is off.



Thanks,

You shouldn't need to use any tape. The washers for the bango bolt keep things from leaking. Usually you don't have to put on any anti-sieze on either. I just through them in with no problems.

It's tough to explain but you might have to take a file to an edge near the overflow valve to get the new one in. I had to on mine. You'll know it if it happens. 30 second job to take a little off the edge.

Tape is a no-no in any application.



Banjo type applications are best done dry. If you have any leaks, replace the washers.

Incidentally, the local Cummins shop stocks overflow valves, but NOT the washers.

Only minor amounts of fuel (couple of teaspoons) should leak out.



Recently I did a mobile call, a bed mounted aux. fuel tank was full and plumbed incorrectly (caused positive pressure even without engine running ). Thank goodness I had just picked up several bags of speedy-dry. It's amazing how much mess a gallon of oily # 2 can make. It makes you hussle!
