Oil Leak

[jmsmith76]

I've had an oil leak for awhile now, been progressively getting worse. I probably go through a quart a week at the moment. It looks to be leaking into the valley, and through the drain hole at the back of the valley. I may not know what I am talking about here, as I don't know a whole lot about the HPO system, just how it works. But it looks to me that the HPO line connects to the oil rail on top of the head and there are 3-4 plugs up there as well. My leak appears to be coming from one of these plugs. Here is a crappy cell phone picture:



Now what exactly is this, and i can't imagine it'd be too hard to fix, but as mentioned above, I don't know much about the HPO system, lol. Any help on this would be greatly appreciated

That looks to be a high pressure oil plug iirc there are 4 per oil rail per head. Not uncommon to leak there, just need to get replacement o-ring for that plug. Go to your local international dealer and buy replacement high pressure oil rail plug o-rings should be able to buy individually.

Sweet, that is exactly what I thought it was. Sounds like an easy fix.

That looks to me like you have blowby oil coming out of the boot on the y off the turbo causing that mess.

Here the part number for the o-ring: (Ford) F4TZ-9N693-A, (International) 1815874C1 (o-ring for HPOP hose to head joint)

There are ports for each cylinder on the HP oil rail, but only one on each side is used for the HP Oil Supply hoses. Cheers!

The boots seemed to be in good shape and all looked good when I reinstalled everything after rebuilding the turbo. I don't think that blowby oil from the boot would cause the amount of oil leak that I have. lol. There is a definite trail of oil around where that plug is, and a good puddle in the valley. Got the new o-rings this morning and hopefully will be able to replace them this weekend. Is there anything I need to know about before replacing them? Just take the plugs out, change the o-rings, and reinstall plugs? Anybody got a clue what the torque spec is on those plugs? Thanks!

Thanks for those part numbers! Got the ones from Ford as there is no International dealer nearby. $3.54 apiece But if it fixes my oil leak, then overpriced o-rings are well worth the money. lol

I don't know what the torque specs are but make sure and lube them a lil before you install them. If they are dry seated you might just rip them from the get go.
