hpop draining back probems can u help?

[lisademski]

i really hope its not some o ring deep in the engine.i did the injector o rings but still have to fill the reservior manually for it to start it must be something small because it still runs reallly reallly good once i get it running

[kanuck15]

is there any oil leaks? if not it might be the check valve in the hpop

what year is the truck?

[lisademski]

um its a late 1994 wich makes it a 1995 7.3 turbo diesel f250 ford.well i didnt put the new pump on but it was happening with the old one too.wich cooked itself because i didnt know what was wrong originally.the guy who did the pump thinks its an o ring inside the engine.or it could be the injector o rings.so i changed the o rings and it didnt fix it.it's actually worse now.i havto fill the pump by hand everytime to get it to start each time.before i did the injectors it was only when it sat overnight.

ok then yes there is a check valve in the hpop that stops oil from draining back, probably went bad

joe, are the 95 hpops the same as the 97+?

[kanuck15]

nope. the 95.5 and 95s are the same, 96 and up arent the same but they are interchangeable
