Ok guys, We has the motor out and did a pretty sizable reseal on most everything we could get to. Added many of the necessary mods and upgrades but for the most part we just reupped the foundation of the motor. Only “performance” part would be the T500 but with regular injectors, it’s not doing much yet.

We got her back in yesterday and she started up fairly quickly, running a little rough at idle but give it gas and it runs pretty well (in Park, nothing on the road yet). I expected this.

What I didn’t expect is to see fuel leaking out of the exhaust manifold on the DS. Leaking from one bolt that we had to put a helicoil in and then it’s leaking from the manifold/uppipe connection. Seems to be pretty clean fuel.

And shes smoking, pretty steady but not horrible.

What do you guys think it is? Stuck injector? We had them all out and put new orings on.

Appreciare the help.

 

Bad injector. Get a new set of 1s from Jim.

 

Thanks Nate, we just pulled the DS and nothing really off except the copper washer has a little Knick in it. Injectors were fine before new orings. Think it would go bad just like that?

 

Well we pulled the DS bank of injectors out and reinstalled/reinspected them. Nothing alarming and we are back to it running again albeit with a little smoke. It’s got a blueish tiny to it.

Just put the code reader on and it’s not giving us anything. Truck revs fine, just smoking.

New injectors were not in the plan now, ugh.

Are there other things I should check?

 

Do you have new pistons and rings? New rings will take some time to seat, smoke would be likely.

 

No new pistons/rings.

But I have oil on the downpipe side of the turbo.

What does that mean?

 

Put a fresh washer on that. They seal when torqued.

 

Yeah I don’t think it’s the injectors now, with oil on the downpipe side of the turbo that seems like an issue.

The pedestal to the block doesn’t seem to be the leak so I have to assume it’s the turbo to the pedestal.

Definitely oil.

Any tips on diagnosing or next steps? Waxed for the day.

 

Also, at idle it’s very little but when you give it constant throttle, you get constant smoke..... engine sounds smooth.

 

Sorry for continuing to post on my own thread!

As I understand it, the air flows through the intake turbine, down into the plenums then to the cylinders, up the uppipes and out through the exhaust turbine etc.

if that’s true (I’d love confirmation) then if the intake turbine is leaking, it’s sending an oily air into my cylinders, hence the smoke and oily leaks in the manifold area.

Thoughts on that hypothesis?

 

Yes drive it to burn off all the oil.

 

Drive it? I’m confused there, I haven’t found the leak.

It idled for a while and I caught this:




What signs should I look for if the turbo seals went?

 

Okay that is alot. Are you sure its oil?

Can you pull the bolt you put the heli-coil in and run it. Maybe you will get lots of fuel out.

 

 

Ok that pic erased the message with it.

Yes, definitely oil.

Are you thinking the helicoil broke into a passage?

This in the intake side and the pic above the boot for that side



Shaft is really tight but the fins have seen better days.

Cant see any oil around the pedestal or turbo, just seeing it on the turbine exhaust to the downpipe.
