200tdi low on power and smoking

This is a 200Tdi in a 110...
The truck began to make a small ticking noise and recieved a valve adjustment, it is now running smooth and quiet but will smoke white smoke at start up.. it also puffs black smoke while accelerating and highway speeds..
the truck also is low on power? puffing black smoke on the highway and having a hard time keeping
up with normal highway speeds...
The truck never smoked before and it appears the valve adjustment has helped with the low range power but it is low on power during hills and highway..
Im not 100% convinced the valves and the power issue were completely related.. it also sounded like my turbo wasnt whistling like it did...
living in Michigan it has been VERY difficult to find a local mechanic who understands this truck and I have owned many Rovers but this is my first diesel and I am no expert...

While using the truck in low range around the ranch it now smokes (whiteish) smoke about the whole time it is being used? the truck never smoked before.. usually just a small puff at start up, then it always ran clean..

Check and or replace the fuel filter. Had one here that went down on power pretty quick and it started to puff white smoke and it was the fuel filter. They will puff white-ish smoke when cold also.

Thank you.. Yes that is suspect.. I was always running the filters offered by RN but a few months back I was given a (Land Rover) genuine filter by the mechanic and I had been suspecting that it has felt different since.. usually when I replace the filter I feel the power gain and smooth opperation... after running this genuine filter I didnt? anyways it hasnt been on very long but I will replace it....

I have logged over 30k miles on this truck in the last couple of years and it just never smoked? even when cold...

Assuming it has an EGR valve, pull it and see how carboned and dirty it and the lines leading to and from it are. Had a badly running Ford powerstroke in the other day with similar symptoms. The EGR was dirtier than a coal miner after a shift. The lines were blocked.

Check the timing. White smoke can come from retarded timing.

I had read this about timing and I had asked the mechanic who did the valves to check it but they did not.... is this a difficult procedure?

It is simple. Read the workshop manual. You set the engine at TDC by aligning a notch in the flywheel centered on the flywheel housing drain. This can be done by eye. Then set the timing with a pin (drill bit will work) through the injection pump drive pulley. If it is a long way off you may have jumped a tooth on the belt.

White smoke under low rpm conditions (and cold) IS un-burned fuel. Black smoke under load (warm engine) is un-burned fuel too (over fueling) but could be engine oil being sucked into the intake. Lots of causes possible, belt timing, slow worn out turbo, turbo hose leak (s), injectors stuck or worn out, IP aneroid stuck .

We don't have an EGR, but there is an oil cyclone (left top side of valve cover) that should be cleaned on occasion, but I don't think you'd get white smoke from it.

First do the filter as noted.
If that does not do the trick check your timing ASAP. I would not drive it much before checking it. Do you know when the timing belt was last changed?

sounds similar to what my 300tdi Discovery did. the timing was off by just a hair. fixed that and then started doing it again a few months later. the second time was bad waste gate and vacuum leaks from turbo so check that too. I found it very frustrating too that I did not not know how to work on the 300tdi and neither did any Rover shops in my area. spent lots on money on bad shop advice, beware.

I have a 110 200 tdi. Mine always smokes a little bit specially with a cold engine. But i have lots of power! And runs like new. It has now 260,000 km on it. Basically just new for a 200tdi But i can hear my turbo very well. It sings like a little bird. So if yu can't hear the turbo check that as well. Is it a original defender 200tdi or dico?

If you have water in your fuel it will smoke white as well. If you have not logged many miles you should check fuel quaility and perhaps run some conditioner like "Howes" to clear up the fuel. I doubt the new filter caused problems.

The belt was changed in the last 20k miles...

About an hour away from where I live we have a great European Dealer and repair shop... they do great work on Defenders but they have pointed out to me that my 110 is the only diesel they have come in...
wishing very much there was a great mechanic around as I do use this truck as a daily driver and not just a weekender....

Yes, and you should always recheck timing after a little running as the belt can settle in. The other worry is a belt that jumped due to an error on the install.

Does this cyclone need to be sealed with silicone... as I was inspecting it last night it appears at some point in its life someone had use a small amount of silicone on the inside of the hole on the valve cover?

It has an o-ring.

how old are your injectors ? 80k is the recommended replacement interval. As said above unburnt fuel is what cause white smoke. Unburnt fuel is usually poor atomization/spray pattern by the injector

It is probably squished flat and covered in oil. Clean it up and you will see it. Replace it to stop leakage. It is a regular o-ring in a groove on the shaft sticking into the valve cover.
