Since the power generated by the turbo depends on the volume of combustion gas generated, look into your fuel delivery system. Your engine might not be receiving the required amount of fuel. Check your fuel pump, filter, injectors, and lines.

SOURCE: mazda 6 2o diesel replaced turbo new unit same

There is a oil drain return from the turbo charger to the sump. If the sump oil level covers the outlet into the sump, oil will build excess pressure tin the turbo causing the sealing rings to leak oil in to the intake manifold. This would cause smokey exhaust and loss of oil. Try this. Drain the sump completely, refill with the exact quantity of oil to Mazda spec. Dip the oil and if the new oil level is lower than the full mark on the dipstick, you have found the cause of the problem. Mark this new level with a scriber or file and fill only to this new level. Hope this is the solution.

SOURCE: I have a mazda 6 2 litre diesel eating oil, what

Mazda say that if your Mazda 6 consumues less than a litre every 900 miles then it within tolerance.
However these cars have a complicated induction mechanism controld by lots of diffrent vacume pots that are inturn controlled by servos, when any one of these becomes faulty the pressure balance between the exhaust side of the turbo and the inlet side becomes inbalanced, resulting in oil being forced through the turbos bearings. Its that simple lol!
The first thing I would check would be the swirl control valve, In the inlet manifold, This gets fouled up by the exhaust gases getting recycled by the egr valve(exhaust gas recycler)
Sooty deposits mix with oil coming from your turbo and jam it closed restricting the amount of air into the engine, and reducing power as well as creating black smoke from your exhaust.
So my advice would be to get your egr valve proffetionally blanked off, and have your induction system checked over.
Hope this helps as I am sure this is a very common problem!

Hi der,lost the turbo in my skoda first,den it started pumping out smoke after a wile,would it be da cat blocked by any chance??


No Chance at all, Its oil leaking into turbo from seal, Burned da tubo Eh. To check, remove turbo and start, loud as all hell but no smoke and you have found the problem, If not check piston rings, valves. ie check compression and check vacuum with gauge.

Loss Of Power When Gas Is Pressed Down


have scan done for fault codes,check turbo pipes for security/leaks or damage, check turbo for wear (remove pipe and check for play at impeller) check intercooler for leaks/damage or internal oil contamination, without me driving/inspecting the vehicle it is more difficult to give proper diagnosis but these things can cause your problem and I would check them first

Loss of power and acceleration on Mazda 6 Turbo diesel 2003


I'm assuming that that smoke was more previlant while going uphill because that's when the turbo would be really spolling up to max psi. I would guess that if you really got on the gas hard and got the turbo going even on a flat surface, that you would notice the smoke too. The loss of power and the white/grey smoke are tell tale signs that your turbo is bad or starting to fail. Good luck!

Hho no mpg increase on turbo diesel


Hi, try to hook up the hho gas hose into a vacuum line of the crank case (with t-connector) NOT directly b4 the turbo. That might help. Its not getting enough vacuum to "pull" the gas from the cell. How much hho production do you get right now? Greetings, ****

Diesel turbo with no power at low revs


this tells me that the injector timing is off just a bit or you may have a weak injector all together.
