OK, here goes...

My friend has a 2000 F-250 4x4 7.3 PS Diesel...

I noticed today that there is oil in the intake plumbing from the airbox to the compressor wheel, and also oil being spit from the turbo through the intercooler and such...

I figured that the intake (compressor wheel) side has oil from the turbo shutting down and reversing the direction the air is being pulled from, right?

So is there a seal in the turbo that goes on these?

Bad blowby?

The truck is also very hard to start in the morning and I think its from the oil being blown in the intake manifolds sitting overnight... possible?

What do you guys think the problem is and how do we fix it?

I'm assuming we have to clean the intercooler out?

 

Please? I know its a Ford and all, but bros before err... trucks?

 

Oil in the intake is normal on the 7.3, Ford routed the crankcase vent back into the intake, causing the oil buildup you see. It causes no problem, but if it bothers him it can be vented to atmosphere just like big truck diesels.

What are the symptoms of his hard starting such as smoke? long cranking? any other symptoms?

 

Ya from what I remember that is normal. Probably need some new glowplugs.

 

VERY long cranking...

And there is a good amount of oil coming from the hose clamps on both sides of the intercooler plumbing... and the compressor housing has oil in it as well...

Should there be oil all in the turbo and such?

 

And/Or a new glowplug relay.

Yes, if the engine breather is blowing oil into the intake there will be oil in there. Trouble with putting the breather into the intake is they usually make enough of a mess you can't tell when you loss a turbo seal and its blowing oil into the intake.

 

So there would be oil in both sides of the compressor?

 

I would change the vent to atmosphere vent...
I would try a glow plug relay first then go to glow plugs...
you can check the relay to see if it is working if you have a multimeter??
I would not stress the oil in the tubes to much (unless it is really excessive)they all have that messy oil in there

 

I have an 03 powerstroke and from the very beginnning I asked why there was oil everywhere, all over the boots and turbo intake. I was given the same advice of changing the venting.

As for early morning starting these guys are all over it again. A very common problem when the glow plug gets weak or fails to come on at all.

 

check the back seal on your hpop if it is leaking it will cause a hard start in am because the injectors are oil fead. there is a tsb on the issue also check the diesel stop.com for additional info thanks,jr

 

I'm sorry, hpop?

 

HPOP=High pressure Oil Pump= takes something like 800PSI to fire a PSD injector

 

my step dads truck and a buddies truck had oil on the turbo and intercooler, both went to ford for service and both times the service tech said this was normal, cranked down the intercooler boots cleaned it up and sent it out.

 

Glow plug relay would be the first thing to check, then glow plugs, oil leaks in the valley, fuel pressure, ect. The oil in the intake is not what is causing his hard starts.
Yup it gets everywhere, pretty easy to change it, to vent to atmosphere. Remove the airbox top and the intake hose back to the crankcase vent, remove the round black crankcase vent from the intake hose and replace with a 4" diameter section of exhaust pipe, remove the breather from the drivers side valve cover, and turn it 180 degrees and remount (make sure the o rings seal when you remount it). The breather will now be pointed towards the rear of the truck, now run some hose (3/4 inch I think) to where ever you want it to end, I ran mine all the way back near the spare tire' cut the top off of a 20 oz soda bottle to make a catch can. If you use a catch can just make sure it can breath, do not seal the catch can to the hose, the can is just to catch the oil residue, the hose still needs to vent pressure.

 

Thanks for the help you guys!

Why would Ford do something so dumb?

And messy?
