Ford 6.4 oil in intake.

Should I be pulling these turbos out to check them or is this normal? Truck will randomly smoke and clear up over a 1-2 minute period.

08 f550 6.4 auto 50k miles



It needs a water pump gasket. Holy fuck did they cream a ton of shit under this hood.

Are you running it hard enough? Turbo seals will leak oil into the intake, but it'll mostly be a residue if you keep it blown out.

It gets a good amount of idle time running a crane. When it's being driven we run it to the floor at all times since it's a gutless wonder. I started it, dropped it into gear and drive about 100 yards into the shop this morning. It's been sitting for 2 weeks since it was driven last.

My 7.3 does the same thing.

Are you sure the smoke isn't from it going into regen?

Edit: Btw, you posted this in the waaaay wrong section. I doubt it'll stay on topic and will turn into a shitfest soon enough.

Edit edit: Id almost bet that oil accumulation is from the crankcase vent system.

Crankcase vent causes that. Search for ccv mod for 7.3s on Google

No big deal. Figured I'd catch some shit soon enough. There is more traffic here during the day.

I was wondering about the crank case vent. Either way I'm not worried about it if it's not too abnormal. This truck has many other problems.

So, I'm assuming I should be replacing the water pump housing.... fuck this thing. I'm so glad I didn't go to school for diesel tech right now!

That one will survive, but a new housing would be nice. Also, make sure you're running CAT ELC, and add a coolant filter.

As to the oil in the intake, it's the PCV system. Not really that big of an issue.

He's better off taking advice from Hellen Keller on good TV shows.

Fuck that kind of engine service at 50,000 miles. What year is this, 1965? Don't give me shit about service truck life. Chevy 283s were dragging grain trucks around once upon a time.

Okay, let's just bring in the expert. @Brimmstone What do you think?

OH! And at 50k miles, it would be interesting to know what the engine hours are. If you figure in idle time, that motor probably has a couple hundred thousand equivalent miles on it.

Nothing that costs that much should require that much maintenance so soon.

I hate the route modern Diesels have gone. I will never own one.

The solution is simple. Jack up the radiator cap and drive a new truck underneath it.

I think you have to take the cab off to get to the cap. I've heard you can drill a hole in the firewall in a certain spot and do it but I'm not sure.

For this, read this, best/fastest I can find for decent info.

Info on this here also. I am doing an EGR/DPF with and full exhaust, intake and mini max to a friend of mines 08 6.4 right now. Scared the shit out of me when pulled the lower hose off of the inter-cooler and it dumped about a quart of oil out on the floor. Was not expecting that at all. To say the least the CCV on his is getting a mod to it too.

Mod it, but don't delete it. I'm not sure what the exact sorcery is, but the rings seem to like having that little touch of vacuum under them.

Look into a slobber bottle.

That is one of the ways the 6.4 likes to kill itself. Cavitation eats through the housing and lets coolant into the oil.

Well, boss decided to gamble on the housing. It's just getting a pump to fix the leak, and cat coolant. I'll check the hours when I get it back together, iirc it was a stupid amount.

I'm guessing this was buried headlight deep in mud at one point. It's been a mess. Broken tow hooks and there was mud packed solid from the intercooler to the fan. I spent about 2 hrs pressure washing all the coolers. Had to chip mud away from the fuel filter cover on top of the motor all idler pulleys replaced because they were sloppy from being packed with mud.

It has a VMAC compressed air system. It took a whole $100 to fix because it needed a tensioner. Previous owner just cut the belt off and said fuck it.

Damn oil field trucks. Run them till they break, then drag them to Richie Bros!

Pump housing looks normal. I've seen much worse. Make sure your grounds are solid because that can cause the erosion. Oil in turbo looks like air filter was clogged and turbo pulled a good vacuum on the crankcase. As stated above dropping the lower CAC tube and having a quart or better drain out isn't that strange.
