alt er godt over.nytt diselfilterhus.har å prøvd med "løse" slanger fra pumpe til tank.+++
men det kan virke som at hvis de pakningene i pumpa er gått,så er det ikke sikkert jeg får det problemet du nevner der med luft i systemet.selv om det er lettest å tro det. har tenkt den tanken lenge jeg å.til jeg fikk se hva det problemet kan gjøre.for jeg har montert en gjennomsiktig slage stubb på den slangen som går inn på filterhus. å da ser jeg jo om dt renner tilbake over natten. noe det IKKE GJØR.
for leser du siste avsnitt på dette så har jo ikke det med at det komer luft i sysyemet.men en indre feil i pumpa som syvende og sist gjør at når bilen har stått lenge så kommer det mye olje inn i sylinderne via pumpa ved oppstart.
har lest om veldig mange med dette problemet nå.
og så lenge de som har dette problemet må la bilen stå på tomgang opp mot en halvtime før de kan kjøre ved kaldstart problemfritt så begynner jeg å lure litt på pumpa ja. for det må jeg gjøre med min å.
nei,skal ikke være lett. får ringe snåsamannen å få han til å legge en helbredenehånd på pajen min kansje..hehe [img]style_emoticons/<#EMO_DIR#>/wink.gif[/img]
Injector Pump
The injector pump has several seals that can and will perish over the lifetime of a diesel engine. However alot of recent failures with diesel engines has been caused by the reduction of sulphur in diesel down to 500 ppm and based on articles that I've read, it is being considered by the fuel / oil companies to reduce it further down to 50ppm. This is were its a little grey for me in that I believe that once you have the seals replaced the seals will be fine on 500 ppm, the failure is caused by the change in fuel mix environment where seals have been conditioned to the higher sulphur levels, but when the sulphur was reduce (less lubrication) it cause them to fail.
My understanding after reading articles is that when the pump seals perish, even though the fuel with in the pump is under a fair amount of pressure, you may not get any tell tale signs of diesel leaking from the pump. So if you inspect the diesel pump and can see a diesel leaking (or if the seals are truely gone - pissing) out of the pump then chances are this could be your source of an air leak within the fuel system.
There is one more seal issue that should be noted here and that is the BIG seal where the pump drive gear bolt together to the engine) that can allow diesel to leak internally into sump / engine block and allow oil to leak into the pump, allow oil to be burn upon a cold start up after the engine has been allowed to stop / lay for a while. Obvious signs to look for is if your oil level increases significantly and or you start find oil within the fuel filter and possibly injectors, you may need to cut open your old fuel filter and check
