yet another problem bloody td5

Never had so many issuises with a td5 .from oil pump to crank to headgasket injector seals and a crack now engine filling with diesal .looking like another cracked head .
Ps im told the injectors also have seals in them which can cause same issuise anyone know off this just about to remove them ( be nice if i find a buggerd o ring but carnt see it tbh

lift of cam cover disconect main injectior harness then turn key look around the injectors for leaks from the rubber seals at top of injector the seals are not expensive and are hopfully what your problem is

Ive aready fitted new seals o rings and copper washers cheers removed injector used a bright touch no oberise sign of cracks .but before i send injectors off for testing is there any seals in the injector that would cause leaks into oil?
Secondly if say the injector adjustments were incorrectly set would this cause overfueling/leaking injector nozzels?

heads cracked

Oh ok john i ll buy this engine then and throw it in .just odd only done 89k no marked or airline cracks in seats .wounderd if it might have been a possible faulty injector or injectors adjusted wrong cheers

you stated already that you have changed the seals and washers on the injectors, if your confident it was done properly, using genuine parts as the cheapo copies are not always good, then i would say head is cracked

I agree with johnlad .

The crack can be very difficult to see. You could use a simple dye penetrant kit / flawfinder . The good news is , depending where the crack is, it can be successfully repaired.

what was manufacture date not when it was registered, There was a change in the heads about then as there are 2 different td5 heads. If your was a 01-99 manufacture you got the old head style i believe

Unsure theres stamp dates on head casting 02 also mine thetype with diesal feed from the front off the head .(flexi from fpr to front ) if u roughly understand me. .odd think theres no fine or evern a airline crack showing in any off the injector walls or in the bottom ..hernce making injector blanks to pressurize diesal system

tough ? ther can only be a few reasons for getting diesel in sump ,crack in head gallery or seals or really poor injector which would have other symptoms as well

I've never yet seen a TD5 injector that has stuck open (dont mean it cant happen though). I've known them not to open and seen them physically damaged when the cam rocker has been set with no gap. As already said take the top cover off and switch the ignition on but dont start the engine. You will see if fuel is leaking past any of the O rings. If all looks well and the engine runs ok then it is defo a cracked head. (tip: dont start the engine with the top cover off or you'll have oil all over your garage ceiling - been there done that ;()
