Oil Leak

[bigcountrysg]

The O-rings for the hpop lines going to the HPO rails on the cylinder head are leaking.

I have the O-ring kit but how hard is it to disconnect the lines. I need to get this fixed ASAP.

It is on my 2002 F-250 7.3L.

Anyone ( Scuffy) wanna come help.

It's easy.

Make sure the motor is cold, unscrew the plug, replace O ring and reinstall.

If the motor is still hot, warm or recently ran... there will be some pressure in the heads and it will ooze oil. Just have papertowels handy.

If you want to be fancy - go to Ford and get the HPOP Oil line removal tool or you can use 2 flat head screwdrivers. Not needed but if you can get lines off, you can use a socket instead to remove the fitting.

So I can remove the line with out disconnecting it. I am not worried about pressure, kinda hard to have pressure when the oil is coming right out.

You'd be surprised. If you want to save some money - return that O ring kit you got.

Go to a hydraulic shop and get some BOSS Viton #5 or #6 O rings and spend maybe 25-50 cents on the fix.

I bought the O-ring kit a while back. Now AE tells me cylinder 8 failed the contribution test. That would be my miss. Oil leak is on the oppisite bank of the engine. So I know that should not cause my failed #8 cylinder.

So I need a new injector and fix the oil leak. 200,006 miles on the truck.

Hold your horses.

#8 fails consistently, you still have the factory original 2002 injectors correct?

I had to replace #8 before. I replaced it with a good used injector I got from my cousin.

So it's no longer a LL injector? It's a standard AD code injector in there?
