In the scheme of things, I have pretty much bottomed the mechanicals on my 80. Just a rebuild on the front diff to make it as good as new. But I still have doubts, concerns call them what you will over the fueling system. Accepting the fact that I am fine on the spanners but clueless on diesel injection systems what could I look at in terms of home mechanics that would make sense? The car starts fantastically well, 1/4 touch of the key. But I get a light grey pungent smoke from cold. This can go when warm, but not always. If I clog it, I get heavy bursts of soot. On top of the head near number one inlet from the manifold there always seems to be some dampness on there. There has always been a bit of a lack of power really. I'd expect a 4.2 x 6 to have much more go than this, but hey it's a 16 year old car. Fuel economy started out at 24mpg but will all the trimmings I am now at around 20mpg which show that it is probably working OK but there are some tweaks that could be done. Changed BEB recently everything still fine. My fuel pick up had no strainer on the end and I have changed two fuel filters now and pulled small trees out them each time. I gave the little nut on the pump half a turn and the click wheel inside got two clicks as well. That did make a difference not nearly so sluggish but it maybe soots a little more when revved hard. This week, the truck stood for several days and simply would not start. In the end I had to pour diesel into the fuel line and after a bit it fired up and throbbed for a bit until it fueled itself properly. I understand that the primer pumps can start to let air in. The pump on the top has never done anything when pumped even for several minutes.
OK Doctors, I'm not looking for an accurate diagnosis here, just some better understanding perhaps of what might be happening and what servicing I could do. It's done 100k of mixed care miles. Some care clearly being non existent. Is there any merit in pulling the injectors and simply looking at them like you would a spark plug? Is having them tested for spray pattern worth doing and expensive? Should I have my IP serviced somehow even though I don't suspect it of being faulty? I have run plenty of injector cleaner through the system.
So, what are your thoughts. I think that this really is an open thread on injection systems for the 1HD-T. As it is, it'll probably run to the end of the World and back. I haven't broken down, it's just that I would like the confidence of knowing what's what and where I might get let down just when I don't want to be. Plus any improvement in performance might be nice.
