diesel knocking

Post by fieldy1978 » Fri Dec 26, 2014 4:27 pm

So i have just ordered a dti mount do i can adjust the diesel pump accurately. I find it very strange they have no zero marks for a default timing. Anyway just found something rather strange that I'm looking for a workaround or replacement. It has been repaired load by the looks of it but if i can bypass then i will. Please see attached pic. Not sure a)what it is and b) what it does but pipes come from diesel pump and go to nothing! !

they are the cold start solenoids, the act on the pump via the vac pipes and diaphragm, they do look in a bit of a mess and the crappy non vac pipe wont help as it will suck flat when warm.

heres how they should be piped up.

Thanks for the great links. When it's running properly i shall replace it all. Hoping to get the dti tomorrow for some fine tuning. Otherwise if it's not pump timing then it's going to be engine out job!

Just a thought....as this happened to me....check that you don't have a broken rocker.
