No oil to turbo, need advice.

[Trying my best]

So I started my truck after putting in my new to me turbo non waste gated banks turbo. Got all excited and ran it for about 30 seconds before I noticed me two oil pressure gauges were at zero. I unscrewed my oil feed line jumped the soloniod and saw that there was no oil. I'm prettier sure I got the correct port for the oil feed, but there is still no oil. I also cracked the line at the oil port down by the filter and did not see any oil there? Any thoughts?

Pretty tough to answer a question like that whan you don't specify where you have the oil supply into. WHERE?

In the spot where banks said to

What kind of engine pressure are you getting? You make it sound ominous like your pump went dead and you're not getting any oil at all...

I wonder, I had oil pressure when I parked it 2 weeks ago

Seen this post? I posted some photos of where the oil should come from and where to plug the factory oil pressure sender.

Don't run the truck without oil to the turbo... it'll kill the bearings in a hurry. Unplug the FSS and crank it over with the starter until oil is pumping out that feed going to the turbo.

Thanks, yep that's were I got mine. When I pulled the plug, oil came out. Huh? I guess I have to pull the turbo and figure out what is going on. I just hope I didn't fry the damn thing. If I did how would I know?

Is there a chance that some crud built up in the oil galley before the plug and made it's way into the turbo feed line and plugged it up? I was thinking somewhere I read that it's common for crud to build up behind that plug since it's a dead end. First thing I would do is pull the turbo feed line off and verify it isn't plugged. I would also turn the engine over with the line still removed and see if you get oil out the oil fitting on the block where you put the turbo feed. Then put the line back on the block and verify you get oil out of the line by the turbo. Then put the line on the turbo and see what happens.

Probably not a big issue, but could be if you run it with dry turbo bearings. I would guess your fine as it sounds like you found it very quickly.

Sounds like plan. What also was strange was that the truck started way to easy. I turned up the fuel on the ip a leaked out some diesel, and I assume that the pressure would have to build up, and after sitting for two weeks, it started up after two cranks, and sounded good too.

When I checked my turbo line for oil I disconnected the IP power wire and cranked it over. No oil came out. I plugged the IP wire back on and let it JUST BARELY fire and checked again, the bottle I stuck the feed line in was full of oil. Try letting it start buy don't let it run.

What I read was....

So I started my truck....I noticed me two oil pressure gauges were at zero.....?

Now these "gauges" would be the factory one, and an aftermarket one, located...where?


This engine sat for two weeks, and you installed a turbo without starting it first to move it, or see if things were still good?


I doubt we have an oil feed line issue here....

The oil pressure gauges have been moved from the stock location to tee off the oil feed line to the turbo. I did bump the engine to see if I had oil coming out of the disconnected oil feed line, but there was none.

putting a gauge on the feed line at the turbo will reduce pressure readings considerably, that passage you hooked up to needs to be CLEAN. or it will gunk the turbo and smoke it in about 2 weeks, in the interim fill the turbo from the top with a squeeze bottle and fire it with the line off, it takes 3 to 10 seconds to read full pressure.

There are 4 oil presure ports on the engine, and when you install a turbo, having both senders right there at the turbo is not your best option. Move one of them to the crank rail, change your oil filter (pre-fill it) and drop your up pipes to remove spin from the turbo. Start it and see if it doesn't help. Optionally you could over-fill the crankcase with oil just in case your oil pickup tube has rusted out, but don't drive it that way.

Thanks. My buddy said I should pull the turbo off and measure the axial and radial bearing play. Do you happen to know how many thousandths there should be? After work tonight Ill try to blow out that line and add oil the turbo.
