What is the best way to clean engine valley to check for oil leak?

I am having an oil leak in my 96 F250 coming down by my starter, thinking it is the hpop because my reservoir is emptying. I rebuilt it about 40 K miles ago.

Anyways, I want to clean the valley so I can powder it and find the leak for sure. I have read some posts saying to have the engine running and others to have it off. What is best?

I am planning on using a degreaser to get it clean, any other suggestions?

Thanks!

I always end up using lots of shop rags and Brake Cleaner. If using something like Castrol SuperClean, Purple Power, or Simple Green be careful as it can etch stuff if left on too long (and if you wash it off use regular pressure water and don't power wash it). Cheers!

I'm with Patrick on using the garden hose and using a degreaser that has been diluted a bit .On a warm engine spray what you needed clean and rinse ,the valley will fill and drain out of the rear hole and I have done it with the engine running without any ill effects .The heat from the warm engine helps dissolving the crud and evaporates the water .

thanks guys. I appreciate it! In cleaning I found a fuel leak as well... that's what I get for retiring it as my daily driver and driving a car instead!

Tape a 1/4" hose to an empty bottle, cut a hole in the Side of the bottle to place shop vac hose over, Suck liquid out of vally, brake clean, search for leak... Just did it yesterday, looks like my HPOP is leaking... either from the flange gasket or Non-servicable plug...
