Long story short I finished doing Arp headstuds on my truck by myself and threw everything back together. Started up fine ran good but then turbo issues started to show.

I started having no boost so I narrowed it down to exhaust leaks at the EGR clamp and the turbo Y-pipe clamp. Fixed it and got boost. Only 20psi though with lag and the turbo was smoking after a 3 sec pull up the street. I think I'm not getting oil to the turbo through the top feed pipe but the drain tube was hot.
I didn't see any oil near the bottom part of the feed tube that goes to the oil cooler.

What would cause no oil to go to the turbo? I have idled the truck for long times so oil should have gone through and the delta temp between the oil and coolant is 1 degree F constant so the oil cooler is working. I have added the 15 quarts of oil to the truck before start up because it was totally dry.

BTW I just rebuilt my turbo. No codes thrown.

My dad always told me It's usually the last thing you touched...

If it truly is not getting oil it won't last very long.

Did you know what you were doing when you "rebuilt" it?

 

Are you positive the turbo isn't getting oil?

The orifice that feeds the turbo from the oil cooler is connected right through the center of the standpipe.

So, if you are getting HPO supplied(which I imagine you are since it runs), your problem would be with the turbo feed line, or in the turbo itself.

 

Yah I'm going to tear the turbo apart again and see whats up. Just weird why the feed tube was dry or seemed that way.

How does the turbo get oil, does turbo suck it up or is it forced in?

 

Also the turbo isn't connected to the standpipe. The standpipe is connected to the branch tubes which is connected to the hpop. And the other part is connected to the oil rail that feeds the injectors.
Unless you are talking about a different standpipe.

 

The standpipe I'm talking about is in your filter housing, your oil filter slides over the top of it.

If you remove the filter standpipe and the turbo feed line and dump oil right into the standpipe hole, oil will overflow from the turbo feed line hole.

 

The turbo is supplied low pressure oil from the filter housing (under pressure). I believe jswartz84 was talking about the oil filter stand pipe.

 

The turbo feed tube was completely dry but the drain tube had oil in it. Turbo had oil in it though. Makes me wonder why it was so hot to smoke from engine bay

 

There is an "updated" turbo oil supply tube available from Ford or International. It's a hard line that replaces the flex line. I'm having a hard time figuring how it could happen as you describe (not doubting you) except to think something is plugged up somewhere. I'm still running the flex line at 160k miles with no issues as far as I know. I have seen flexible brake lines fail internally and cause a rotor to drag, maybe it's something like that.

Just a thought but you didn't happen to leave the drain line on the engine and put a paper towel or rag in there?

 

Every time i worked on my engine inevitably i would get oil on the turbo housing. It always smoked a bit after i was done doing anything under the hood. If the turbo wasnt getting oil youd be rebuilding it again by now. You could always take the supply line off the turbo side and start it for a second with the end in a catch bowl. Youll know right away if it is getting oil. I miss aligned the drain tube on my turbo and had 2 gallons on the ground in less than 3min.

 

Took the turbo apart and still looked completely new. No damage. Turns out it got feed to it but I don't know how much, just the oil drained all out and it looked as there was none. Going to send the turbo out to get rebalanced. I'll have them also check why the turbo was getting so hot and smoking.

 

Your not going to see any standing oil in the drain line.
It drops down in front of the HPOP and then runs down
in the block to the pan. It's gravity and not under pressure
at that point.

You sure the turbo wasn't just burning off some cosmoline anti-rust coating or the clamps weren't burning off PB Blaster or anti-seize?

Brand new turbo practically but there was wd40 and oil in there. I noticed a small amount of oil in the compressor housing when I took it out too.

Just doesn't make sense why it would only make barely 20lbs of boost. Although I forgot about the relearn period and if it effects it that much.

I'm going to go over all the pipes again for exhaust leaks too.

 

Disconnect oil line from turbo, stick end of line of a catch can and start the engine. Pretty simple to check for flow.
