Mk3 mondeo engine loud ticking like grinding all the time.just had problem with injectors.had all 4 replaced.the garage says piston slap


Is this a new noise your hearing? If your mechanic has correctly diagnosed the noise find more info here:

http://www.autos.ca/auto-tech/auto-tech-noisy-engine-it-might-be-piston-slap/

The distinctive noise of a diesel engine is variably called diesel clatter, diesel nailing, or diesel knock. Diesel clatter is caused largely by the diesel combustion process; the sudden ignition of the diesel fuel when injected into the combustion chamber causes a pressure wave. Engine designers can reduce diesel clatter through: indirect injection; pilot or pre-injection; injection timing; injection rate; compression ratio; turbo boost; and exhaust gas recirculation (EGR).

My td 27 diesel engine the engine luck on sylinder 2@and i sove it but it steel lock again on the same sylinder 2, i se the oil pumping what is the cause?


not the oil pump
most likely a leaking injector causing a hydraulic lock where the fuel sitting on top of the piston is not allowing it to go over tdc
pull all the injectors
turn it over and push the fluid out the injector holes
have the injectors professionally serviced
bad news if you get water out of the injector hole as that indicates a head gasket or cracked head allowing water into the cylinder

Kubota M 5030 2.8 6 cyl. Diesel in oil sump. Why?


Diesel gets in the sump from an seal leaking in the fuel pump through to the drive gear and out into the sump. If it has an inline pump( one where the injector lines are in a row at the top of the pump) the fuel will be leaking past the plunger elements and into the pump sump which then drains back tot he engine sump. IF it is slight but consistent sometimes injectors will dribble when shut down and the fuel will by pass the piston rings into the sump. Talk with a diesel pump and injector repair specialist for any faults particular to the Kubota fuel system

Hi, I own a 3.0 d4d toyota fortuner (same engine as 3.0 d4d hilux) and as of yesterday it started belching white smoke. it starts and idles perfectly fine, the exhaust just smells off. not like unburnt...


White smoke on diesel engines, means water in combustion chamber. Blue smoke means oil.
In what condition was the filter you removed? How bad? Temperature issues? Missing coolant maybe? If yes, you might as well have an internal leak. Some gasket maybe. Check all you vital fluids levels. If anything missing, take the time to empty the engine oil on a can, and check the colour. If it will look like chocolate brown, then you do have a leak from the inside.

Smoke out of tailpipe on startup


ask a question. White, blue, black? its most likely steam on this new of a car. nothing to worry about. if blue, its burning oil, blue on start up is leaky valve seals, black on startup is leaky injectors, real white smoke (tons will come out) not steam, is blown head gasket or cracked head/block

Knock in engine


it can also be an injector. injectors tend to supply more diesel after long service. To check if this is the problem: let the motor idle whilst it knocks. start from the front of the motor- loosen no1 injector fuel line- the motor will start idling roughly as fuel supply to no1 piston is starved. If the knock persists, tighten the fuel line and move to no2 injector and repeat the process. the knock will gradually go away if one of the injectors' fuel lines are loosened and the injector is faulty. If you get 1 or more injectors with these symptoms, remove and replace the injector. If the problem persists, it can either be that one of the diesel pump plungers are worn and supplies too much fuel or a big end bearing is faulty.
