What are you putting in it.

[Tony V]

What do you mean? I hear the hpop leaks frequently on these good ole 7.3s and i figured i'd do it. If your talking turbo im gettina 38r

It's easy.

I wouldn't do it just to do it though. There's no need to unless they are leaking.

Well im not sure if they are leaking. I cant really tell where my truck is leaking but there is oil in the valley.

If you do end up doing it. A stubby wrench makes a world of difference. You can find many many writeups on how the o-rings are changed here.

[Tony V]

[Tony V]

It will be well worth your time to clean the valley with Simple Green and a garden hose (yea, real easy this time of year!) and determine exactly where your oil leak is coming from. You can spend a lot of time and $ throwing parts at a leak and never fixing it since there are so many points both front and rear of the valley that can fail.

HPOP discharge lines, HPOP front engine cover gasket, HPOP rear plug, HPOP serviceable "non-serviceable" plug, oil rail plugs, HPOP hoses, turbo pedestal o-rings, turbo EBPV actuator, ICP sensor and the list goes on.
