Mazda 6 2o diesel replaced turbo new unit same

It's pretty easy but you'll need to work under the vehicle, so make sure that the vehicle is on ramps or axle stands. Don't work under the vehicle just on a jack as it can slip & you can be killed.! Run the engine for 5 minutes to warm up the oil. Remove the sump plug & drain the oil into a suitable container. Remove all the bolts which hold the sump onto the bottom of the engin & drop it down. (sometimes there are additional sump bolts near the crankshaft which are on the side of the engine) You may need to prize the sump off. Do this slowly & carefully to avoid damage to yourself, the engine & to avoid twisting the sump tray. The oil pickup will now be seen. Remove the 1 or 2 bolts securing it. Wash it with degreasant or hot water & detergent Reftitting is the opposite of dismantling, BUT, You will need to clean-up both of the mating-faces of the sump & bottom of the engine. When they're clean, use a new sump gasket & a good oil-sealing gasket-sealant. Follow the instructions on the sealant about drying times. Bolt the sump back in position, using the correct bolt sequence & torque tightness. Replace the sump bolt. Fit a new oild filter & refill with new, clean oil.

i dont think a fuel injector leak could cause damage to a turbo. The turbo pushes more air into the engine so it can burn more fuel with the added air. a fuel leak either inside or outside the motor shouldn't have any affect at all on the turbo. if the fuel isn't getting into the cylinder to burn then it wont create the gases from that cylinder to spin the turbo up to proper speed, but the engine would run really rough if it wasn't getting fuel in one cylinder, same as taking off a spark plug wire on a gas engine.

there are two oil lines to the turbo
one line is a pressure line that delivers engine oil at pump pressure to the turbo
the other is a low pressure line that drains the oil back to the sump
determine which line is leaking and replace or fix and replace the gaskets or "O" rings

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.

Hi I have a problem, to start my 2010 3 liter mazda bt50.
I change the fuel pump but still the problem didn't solve

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!

You will have to replace the HP pump

You dont say weather its a petrol or diesel engine as there a slight differance in the answer and if a turbo on a diesel thats even more of a differance, but taking it a petrol .
Well to start with the white smoke Isent smoke its water and after going through the engine it turns into Steam and thats what you see..
Running on 3 clyinders is caused through 1 cylinder isent working as a engine should and has a bad valve or a broken piston ring or more and even a cracked head and gasket letting the water through,,,also the broken ring works like a oil pump as if not firing given you power then it works like a oil pump and pumps it into the cylinder that dosent work only pumping oil into the hot exhaust system while running.CAUSING SMOKE
And if a turbo then could be the turbo bearings worn and pushing oil into the engine and still doing the same as before.
Let me know how you get on. RON

I don't wish to worry you but I think the turbo kicks in at around 2500rpm and it sounds like it isn't doing so, hence the management light coming on. It could be that failing. Be careful here, apparently the turbo uses the engine oil to maintain its operating temperature and if the turbo seals fail in anyway it eats the engine oil, with the resulting total failure of the power unit. So if you do nothing else, keep an eye on the engine oil level. (You may also notice oil smoke out the exhaust as well).
Unfortunately it looks like a trip to the dealer for them to check what the engine management is saying.

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