), earlier I changed the oil, air filter, oil filter and fuel filter on the 400. It was badly needed, the oil was gone beyond black and the car was getting smokier under acceleration. Anyway since me doing the filter changes she has been taking a few seconds of cranking to start, before she started immediately. I was very careful when changing the fuel filter not to damage the rubber tubing stuff to and from the filter, but obviously air is getting in somewhere. Just a few minutes ago I decided to give the priming bulb a few squeezes to see would I notice anything noteable, after a few squeezes, before the bulb got very hard diesel started coming out of the bleedscrew, not squirting but a decent ooze of it, enough to see quite clearly under urban street lighting. So would I be correct in thinking that's where the air is getting in ?? I would have thought no leak from there should be happening. Old filter is in the wheely bin so I plan to take the old bleed screw and see how that goes in the morning, failing that I suppose some PTFE tape stuff may be worth a try.I know that diesel would be easier to force out than air getting in but I do think that the screw should be a good enough fit not to be letting diesel out before the bulb is decently hard.
I will report back on how trying the old screw goes, hopefully it is that rather than the threads on the actual filter. I do hope it's not the rubber prime bulb or the tubing. Fingers crossed.
