05-07 Ford 6.0 problem

I have a friend with either a 05 or 07 Ford F250 with the 6.0 diesel engine. Both our kids are in the high school band which means we get to haul field show props to the competitions. He was hauling a trailer about 2 weeks ago that wasn"t really heavy but it had alot of wind resistance.

When we got back that night he said that as long s we were running about 55--60 it was fine but when we are doing 65-70 his oil pressure went up to around 90 and said his turbo was rattling bad. Slow back down and everything was fine.

They have a travel camper that they pull and I assume not that fast but he said this is the first time it has happened. Any ideas what it might be? I told him to go to the Powerstroke board but he said they want $18 just to join that and i knew that someone on here would know.

thanks!

There's lots of help out there that wont' cost you anything. Try posting your question here:

I am not an expert, but the 6.0 had numerous problems. It should have a 100 mile warranty. I would take it into the deale, have it diagnosed and make a decision from there.

Jeff, first check the obvious, Oil, smell it, is the level Higher than normal, Does it smell Like DSL If it does he may have lost the rear seal on the DSL pump His engine may very well be shot by now. If the turbo is rattling that is not a good thing! get it to Ford ASAP Tomorrow!
5 Yrs ago a neighbor was raking hay with his JD4430, checked it late AM when he fired it off, sat his tractor till late Afternoon early evening when he finished the field, as he was Idling it down to cool it off the Turbo went to making a rattling noise, He pulled the dip stick and checked the oil, it was 2 gal high, smelled like DSL, engine was shot when JD looked at it.
Hope this helps.

The early 03 models had some problems, after that they seem to run quite well. sounds like a seal or aftercooler problem to me. Check the oil level, cross your fingers, that should tell you which way to go.

It sounds like the EGR valve is pressurizing the crankcase. He even could have a blowen head gasket or cracked head. Either way he has a real problem that he needs to get checked ASAP. Let us know what he finds.

That 6.0 motor was a repair bill waiting to happened. To go from the power stroke family to that motor was a real mistake. Newer Ford diesels around here are just about non-existent now. The local dealer here will not order you a diesel. HE used to sell 20-25 diesels each year. In 2005 there was one time he had every Diesel he sold in the shop at the same time. He says that those trucks cost him $250,000 dollars. He said Ford's warranty did not pay very well and then the owners wanted to trade them off right away. Toward the end of dealing with them he would just take them to the car auctions and let them go for whatever they brought.

He now has a lot of Power strokes that he buys in the south to sell to the guys that want diesels. He gets in some real good looking trucks that are way cheaper than the new ones.

have him go to www.thedieselstop.com. It's free to join and you can get some better insight there. HTH

ou do know that all those troubles ended the relation ship between Ford and IH/Navistar (the supplier of diesel engines to Ford for ever). Starting about 2010 or 2011, Ford designed & built their own diesel engines. No more Navistar for Ford!

Thanks for the replies and advice everyone. I"ll tell him about the website and to check the oil and everything. I know the first 6.0"s had alot of problems but honestly we have Dodges so I didn"t really keep up with the issues on it.

I"ll let you know what he finds out on it.
thanks again!

How does he know the oil pressure went to 90? The factory gauge is really a "dummy" gauge. They read about the o or r in normal once oil pressure passes about 7 psi. Turbo rattle? They are known for the unison ring sticking. I suppose it"s possible for the turbine to be contacting the housing. If that be the case, it"s just a matter of time before the turbo has a major failure, usually broken shaft. Depending on where the unison ring sticks dictates on weather they run good or poor. Boost should never go above 25 psi or there will be a set of headgaskets in your future. An indicator of leaking headgaskets is pushing coolant out the overflow tank cap.
It"s not possible for the EGR valve to pressurize the crankcase. Typical EGR issues are sticking open causing lots of black smoke.
With a speed/load concern I would first do a low side flow test on the fuel system. Fuel pressue shouldn"t ever dip below 45psi. Below 45 you start hammering injectors. Hammered injectors usually show up as misfires on a cold start up.
If you take it to the dealer, they"re highly likely to want to put fuel filters in. I recommend getting Ford filters. Aftermarket filters don"t have a water separator (Wix included) like the O.E. do. You can change them yourself and save a few $$. Don"t forget to drain the water trap, it"s the 6mm allen plug on the side of the lower filter housing.

Thank you Brian,,nice see a breath of sanity once in awhile ! lol
