2LTE no power lots of smoke HELP!!

[surflife]

Hello all, I am having trouble diagnosing my recent issue with my Surf.
Was driving down the highway yesterday when I started loosing power and was trying to accelerate but the truck was slowing down. I thought maybe it was fuel related but once I got it home and tested for fuel blockages found that there were none. Checked at the primer pump, the injection pump and at the injectors by cracking each while the truck ran.
It runs really rough and smokes like crazy. I have recently replaced the injection pump and suspected that timing could be an issue so I pulled the timing cover to inspect. All timing marks line up correctly and everything looks good there.
I'm not sure what to do next.
The truck has been using oil for the past while and usually has lots in the intake.
I think turbo seals could be gone but would this cause that much smoke an loss of power? I guess compression test could be an idea of something to try to make sure everything is ok inside.
If you guys can think of anything else please let me know and I'll try it.
Thanks in advance.

Check the small vacuum pipe, as indicated in this photo,

is secure. They can swell due to oil contamination and come loose resulting in loss of turbo boost pressure.

Thanks for the advice. I'll have a look. I have had this pipe come off before but it didn't cause this much trouble. Truck is missing lots and smoking like crazy. Idling really low compared to normal. As soon as I give it throttle it bogs down and wants to stall. I have to blip the throttle to keep it running.
I think it may be time for the 1UZ to find a new home.
Sick of dealing with this heap of an engine. Been running it now for almost 5 years and it's been 1 thing after another. I would like to get it running until I find a replacement daily driver for the time being while doing the swap.

Checked the pipes and all looks the same as before the power loss and smoke.
Could a valve be stuck open and leaking a ton of fuel in? Checked coolant and it looks good. Don't think head gasket is shot. It didn't overheat or anything. Compression test is next and then check out the turbo.

I have just had the same problems with mine and went through the same process of elimination. After trawling through the forum I decided to test the TPS (throttle position sensor) using a multimeter that has ohms, and my very limited electrical knowledge. I found a fault and managed to get one from a forum member.
It's a bit fiddly to get back on but all is now ok.
Good luck.

I assume that it's the big sensor on the throttle body that's labelled throttle sensor.
Im wondering which wires you tested as there are 4 in the harness. Also what should the reading be?

Hope this helps.

have you tried checking the turbo? it might be damage or defective that cause too much smoke.

i think it's the turbo that causes to much smoke and loss of power.
one of my colleague encountered this problem when he tested a Mitsubishi pick-up/truck that on sale....during the test run the engine emits smoke and losing power.
The mechanic check the turbo and found too much oil inside the unit which is not good. He was then advise to replace the turbo unit.

In addition to your query, when the oil mixes with the air that runs inside the engine...it generates too much smoke even in the gasoline engine.

ok, would oil in the turbo cause stalling ? had oil in air filter in an astra and it stalled every time went round a corner. my truck has stalled 3 times in last 2 weeks after coming up steep hill into a bend, pretty scary as all steering goes down aswell.
could it be stuff in the turbo?

forgot to add truck is automatic

Hi, did you solve your turbo issue?

If not does yours do this when you run the engine up?

I forgot to add, if the oil gets into the combustion chamber it's fuel for the engine....hence smoke.

i guess it was the oil causing the problem. It is not normal for the oil to get into the air filter. when the oil enters in to the air filter or turbo's...maybe the oil seals are busted as i know. but more than that i cannot presume what are the other causes of the problem.

thanx for the replies.

@andy, i dont know what it sounds like with all the gubbins off the turbo as i didnt do it myself, the garage did, had turbo reconned and all was good untill yesterday when it cut out again, gonna have a look at all the vacume hoses and see if its that

cheers
