SOURCE: how to fix and clean the mazda 5 diesel

You can clear these if less than 60% blocked by giving the car a good blast on the motorway going through the revs. If your car is on limp mode you do need to replace the particulate filter as the blockage is too much to regenerate. I have found a company that does these very cheap and are technicly brilliant i had many questions and they seemed to answer correctly with confidence. They supplied the part to me for £500, i have checked from this for the automotive solutions guys that did it for £450 but couldnt find them which is why i went with these. The company is Onlineautomotive.co.uk and i spoke to someone Called Darrell. There number is anyone wants it is 0844 880 4149 he did giv me a direct number but im sure he wouldnt want me to list that on here as its his work mobile.

SOURCE: mazda bravo blowing white smoke

With regards to the above problem, I have just recently experienced the exact same thing with a 98 Mazda Bravo b2500 (this is a diesel).The symptoms were after driving over some corrugated dirt roads the vehicle would not rev over 2000 rpm and at that point would blow heaps of white smoke and misfire, but would idle beautifully and rev smoothly up to the 2000 rpm. Also noticed when vehicle was cold it would drive good for about 5-10 mins then symptoms would start again.

Fuel filters were changed, sediment trap cleaned,different fuel tried and checked all lines and system for air entry, problem still persisted. While checking injector pump lift pump pressure I noticed that the pressure would drop right off at the 2000 rpm, maybe a lift pump problem?? After consulting the workshop manual I found there is a small stainless steel thimble filter under the injector pump fuel line input union bolt, held in place with a small spring. Pulled this out to have a look and it was full of crud, cleaned it all up and put back together and have a guess what......goes like a brand new truck!!

Cheers

Why does a smoke pick up steam?


Because gasoline has water in it at molecular level. When it burns under pressure, the water turns to steam. In summer you can't see it, but in winter, it shows as water vapour in cold air and drips as water from the exhaust as it condenses against cold metal.

When you say "sometimes", whad do you mean exactly? When cold? When warm? When accellerating?
White exhaust smoke (which has a sweet smell) is often an indication of a blown head gasket. You'll need a compression test or test the antifreeze against exhaust gas contamination. Although the compression test will tell you more about the contition of the head gasket.
Where exactly does the white smoke come from under the hood? Maybe there's a puncture somewhere on the radiator hose or heater hose and the antifreeze sprays on the exhaust? Please check. There still is a tiny bit of hope it's not the gasket...

1997 mazda e2000 van which is blowing black smoke


if it takes 5-10 mins of running before black smoke disappear i think you could have broken rings causing engine oil into the combustion chamber. you could observe white smoke if you have just changed oil.
solution would be to replace piston rings. it would save u a lot if u could diy.

I have a 98 mazda 626 only when its cold i have like a blue gray or even white smoke coming from the exhaust don't know what it could be?


Your exhaust valves have deposits on them that don't allow for a good seal when the engine is cold, or your piston rings are worn, allowing oil to get past when the engine is cold. In either case the seals improve as the engine warms, making the smoke go away. You can try to see if an oil additive will improve your situation.

Mazda bravo blowing white smoke


blowing white smoke is almost always a symptom of an engine coolant leak at the cylinder head gasket. remove each spark plug and look for a dis-colored plug to find which cylinder is leaking.
