Mazda B2500 Turbo Pump

My mechanic/serviceman informed me about my Mazada's turbo pump leaking some oils during my latest car service.He said that if i dont attend to replace my turbo pump, the power of my pick-up will reduce. I just wanted to know what are the most common problems encountered on this particular part of the car and whether it can be repaired. Also it would be of great help if someone can give me tips on how to identify the turbo pump problem in the layman's point of view and how to address the problems. (Mazada B2500 Fighter Malaysia Model 2002)

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.

Hi I have put a new turbo on my mazda 6 diesel. There is no oil leak there is just loss of power as if there is no turbo. It's as if max speed I can get upto is 90. Part from that there car runs g


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.

My toyota 3C turbo diesel engine the turbo compressor is flooding of oil . I can.t trace where it is coming from That is why I am searching service manual for this turbo charger. 12ct


Hi,

If your turbo housing is getting flooded with oil the it can only come from the shaft seal on the inside of the turbo.

You will need to remove it and replace the shaft seal.

Engine is using 1/2 qt of oil every 800mi, 1.8T '04 Cabriolet


Your mechanic is spot on. The A4's are notorious for turbo overheating and failure. The oil burn is coming in the TURBO itself and then being distributed to 2.3.4 as a side effect. Your not noticing blue smoke because your catalytic converter is doing its job and the minor smoke being generated is being taken care of in the CAT. If you continue to drive as is you will run a certain risk of catalytic converter damage, cylinder damage from fouling (cylinder wash) build up, sludge, etc. If your mechanic has the knowledge on this specifc model there is a way to test the turbo output and turbo heat generation to absolutely confirm. One last thing. in ANY turbo car its imperative to run QUALITY oils not your local wal-mart brand or no name. Many people are not familiar with the demands on a TURBO engine and oil change facilities pull standard oil from 55 gallon drums via a pump.. so you arent feeding your car properly. The AVG (Audi/Volkswagen) company recommends FULL SYNTHETIC and either Castrol or Mobil 1. I have a Turbo Diesel and use Mobil1 as my choice. The recommended oil for your car via their web page is Current Vehicle: Year: spacer.gif 2003 Make: spacer.gif Audi Model: spacer.gif A4 Quattro Engine Type: spacer.gif 4cyl. 1.8Liter Turbocharged
button_viewprintable.gif spacer.gif Mobil 1 0W-40
A fully synthetic motor oil, Mobil 1 0W-40 with SuperSyn Technology exceeds industry standards and the major leading builder requirements, enabling the product to keep performing well after conventional oils cannot. Mobil 1 is recommended by leading car manufacturers as initial fill

Have Mazda bravo B2600 4WD ,has white smoke & oil from exhaust. Running rough as if on 3 cylinder


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

1996 turbo deisel fuel and oil leak.


The fuel pump is located under the turbo on that truck. It is most likley washing sediment/old fluids out of the vally of toyr engine. It is also driven by a push rod that ths cam drives, so the lower pump o-ring may be leaking too. You can change the fuel pump without pulling the turbo. Good Luck
