i have read many posts about ticking noises and they sound like they are what's going on with mine. got it narrowed down to lift pump or overflow valve. is there any way to find out for sure which one it is? i'd hate to have to buy them both.

 

u can take ur lif pump off and clean the filter screen inside it.....and if u have never changed the overflow valve then do so they're not too bad...ask infidel for the contact info for the 25$ overflow valve...

 

Use a piece of pipe, wood dowel or long screwdriver, one end against your ear, the other on the suspected ticker to find the source.

Replacing the OF valve is a five minute one wrench job if you don't drop the sealing washers, stuff a rag under the valve to catch a falling washer. Remove the old valve and put new one in it's place. Occasionally the notch in the manifold you see to the left of the OF valve in the picture needs to be filed or ground a little to allow the old valve to be removed. Don't bend the line to remove the valve, it will make it very difficult to line up again. New style OF valves don't always have the retainer on top that says not to remove, don't worry it's just a design change.

The object in the lower left corner is the oil fill cap.



You won't find a better price on an overflow valve than here
