Engine knocking and oil blowing from turbo

[bullfrog1234]

While idling my truck it started running rough and shut down. I attempted to restart and it did, but the truck was vibriating so I shut it down. When I opened the hood I noticed a lot of oil coming from the turbo and exhaust pipe. I pulled the turbo, but did not notice a wobble or any thing wrong off hand. I checked the exhaust manifold, but came up with a little oil on the fingers. Now I am stumped on whether it is the turbo or something else. Anyone else have this issue?

Did you happen to notice if there was any oil pressure when you re-started the engine?

 

[Srjeeper]

Any chance your J pipe could be full of water and not letting the exhaust out?

Secondly, was it knocking or just running rough?


When they idle on cooler days they will build up moisture in the exhaust and it'll leak out around the clamps and look oilly as it drips down over the starter. Then when you run it a bit it'll warm up, burn the moisture out of the exhaust and be good to go.

There was an incident quite a while back where somone had nearly the same problem and here the J pipe was full from heavy rain and the exhaust couldn't get out.

Just something to consider...

If you are sure its oil then DON'T RUN IT. See the runaway engine thread.

I did not notice the oil pressure as I was trying to stop the engine. I check this tomorrow. I have oil on my dipstick up to the 1 quart low. Pulled valve
Covers and the Rods are tight. I know this does not rule out the possible pistons , but I am looking for the easy fix first.

My guess id the turbo is under duress....which happens to stuff that truns 9,000 rpm and builds pressure.

Was the engine just vibrating or knocking also?

Pull off the turbo pipe going to the intake. If there is no oil in there, you have an internal problem. If it's just a little damp in the pipe you're ok (sometimes turbos will have a little normal seepage) but if there is quite a bit of oil in there your turbo is going bad.

From what you're telling so far it sounds internal. Unless the turbo shaft has quite a bit of play in it, it's uncommon for them to leak oil.

You can remove the oil feed line(adaptor fitting), from the side of the block. Then put a pipe plug in it and start the truck with no turbo installed. That will eliminate the turbo and let you continue to diagnose the engine.

I will cap the oil line. And see if it knocks again, and if I have oil blowing out the exhaust. I cleaned the turbo and run hot water throught the oil ports, nothing leaked on either side, does this mean my turbo is ok or will the oil pressure push out where as water will not?

Is the oil coming out of the slober tube?if so,it might not be your turbo at all!

That deuce explosion video looks fake.

 

[bullfrog1234]

It is some coming from the tube and a lot from the exhaust side of turbo and leaking all over my starter.

The Deuce explosion video soundtrack sounds like a normal Detroit 8V92 in a HEMMT under full throttle in low gear until it grenaded. I'm with you Rayzer!!!

It's a real video.....

 

[bullfrog1234]

It is officially oil coming out by the buckets

Time to pull the pan and look up in there to see what's wrong. You've got a major problem somewhere.

plym49,
With all due respect (I said that right), With all due respect, there is no way that video is real. A fireball coming through the hood? Sure the smoke screen never allowed the hood to be shown once the "explosion" took place but I never saw the shrapnel from the hood being blown away and the "wood shards" flying around at the beginning of the "explosion" make me call BS. The soundtrack included sounds like a 8V92 gettin with it. Sorry for the highjack, OP. For What it's worth, mine's not done that but if you felt the vibration in the truck, the turbo is not the culprit.

Ya, the vid is most definatly fake.

Indeed I do have a work of art in the shop. This one is going to take some time along with many 12oz little buddies , so my
Turbo charger is in good shape. Now I move on to getting into the heads and rings. Just in time for the summer time heat and bugs.
