Truck wont start! Made a noise & now there is a puddle of oil under it.

[Tractorluvindj]

Ok 1st of all the truck is my dads 1997 Ford 7.3 Powerstoke (with 290k miles)
-
It was like 6 degrees out
(The glow plugs are pretty bad on the truck & the truck dosnt have a block heater)
-
My dad needed the truck so he tryed starting it.
-
It wouldnt start cause it was to cold
-
After a few tryes it made a noise, & now there is a puddle of oil under it
(The puddle is about a 20" circle & is about a 1/2" deep)
-
BTW: My dads truck has never leaked any oil before

Sounds like you may have blown an HPOP O ring

[Tractorluvindj]

How big of a deal is that

[daveyburt]

if he is right with the hpop oring, the part should be pretty cheap. if you know where the hpop is, you could look around there for the source of the oil. the orings are usually on the connecting lines as maybe where the hpop itself mounts to the engine (at where it gets it's oil).

this is mostly assumption from understanding my 7.3 a little so....
take with salt.

hope you figure it out!

hpop orings for the set is around $30 at ford. look down in the valley of the motor to see if there is any oil puddled up in there

super easy fix BTW. i did it with the wrong tools in less than half an hour

Check the valley for oil first, get someone to start it while you look, thats the easiest way to find the leak.
