I think this is real big when it comes to the "drip" issue. We could have done what Ford could not.
Now how do we capture this, prove it to the point that some will take the advise!

They know if they are telling people to use 5W30 oil.
I agree there buddy......however how do we get FTE on the know
Moreover, able to back up our hypothesis. There some that, if give a gold bullet to shoot the number one enemy would gripe and say there is no way………….hum…..a silver one would work better and I can buy it cheaper….
So the main objective…is to find all those that had the leak, remained with old weight oil, and still have leak, two, three times more.

An interesting twist to this topic....I installed an Auto Meter oil pressure gage since the factory gage is the same as an idiot light because it reads normal above 7 PSI and low under 7 PSI (PSD Bible).
With a new change of Motorcraft 15W40, 40 deg. cold idle is 80 PSI. 2000 RPM with no warmup is off the scale, at least 120 - 130 PSI. Warm idle is 70 PSI. 2000 RPM the pressure maxed out hot at 90 PSI. I was beginning to get some seepage past the rear main.
I changed the oil to 5-40 Mobil Delvac 1. Cold Idle is 70 PSI. 2000 RPM cold is 90PSI. Hot idle is 30 PSI and 2000 RPM hot cruise is 75 PSI.
Best thing is that rear main seepage stopped. These engines are supposed to have a 75 PSI pressure relief valve (PSD Bible). Anything over 90 PSI is generally considered excessive. I have heard experienced mechanics say that excessive oil pressure will cause the rear main to leak. This may be why so many on this forum say their dealer is recommending 5W30.
Hello all,
I think going to a lighter oil is the wrong approach. What is wrong
is the pressure relief valve not opening to hold 70 PSI or so.
120-130 is too much!!!
Has anyone thought about this and/or passed this along to Ford???
I have a new 6.0 due to be picked up in July (build 4/26) and
it seems to me a lighter spring on the valve is the answer to the problem.
Replacing seal after seal ain't the answer.....
If I've missed something, please redirect.....
Thanks,
PSD 6-oh!

PSD-6....what we are trying to do here is give a solution to a problem with out the help or interaction of Ford. By going to the synthetic oil, it solves most of the inherent problems with oil leaks and a bit of a side benefit....
is the injectors…they love the stuff.

No disrespect...I'm sure the syn is good stuff...I use it in an '88 T'bird.
But...(!) I don't think oil viscosity is the cure....pressure regulation has
to be a LOT less than 120-130 PSI....even if Ford/International has
to rethink the regulator....seals just won't take but so much....
I'll keep an eye on this one!
I don't want any drip-pans under my new 40K truck!!
Thanks,
PSD-6 Oh!
Tim, or one of you other knowlegable respondants, I have always heard that an engine needs to be fully broken in before you switch to a synthetic. My question is at what milage is a diesel broken in, and can you switch back to petrol based oil at a later date?

IMO First oil change.

Per the PSD Bible, these engines have a pressure relief valve set at 75 pounds. Problem is, it doesn't work on any engine that had been checked against a gage.

Bob...
you put Delvac 5w-30 in your truck...
I asked Kiwik Kar to do that and they put 15w-40 !!!!
I am SO mad !!!
And in talking to the arrogant incompetents they say it's not made !!!
and don't think the fact they didn't tell me was an issue ???
John, on Mobil's site, Delvac one only comes as 5W40 If they put in 15 W40 it aint Delvac 1. I think we need the 40 part cause hot idle is 29 pounds, Sounds low but not from my experience with diesels. The old mechanics used to say any oil pressure at hot idle was ok, it is when you start chuggin that you need 70 lbs.

Then maybe they didn't even put in Delvac 1 because they were adamant that it was 15w40 !!!
Going to talk to their mgmt tomorrow...
Don't you just love the knowledge of the folks we take our trucks to....
All they needed to do was do two minutes of reading and they would have been as well-informed as the customer…ug…to difficult to do.
