Since you have a shop local to you that checked your injectors. Why not take the pump or even the whole truck to them to look at? Something is being missed and a fresh set of eyes on it may just find it.
Update:
So I took the block to a local machine shop to have them change them cam bearings and hot tank it. While talking with them I asked about buying just a single piston set.
He knew the right person to talk to, from the same place I used, and he was able to order me a set for one piston...
I'll have to dig around to see if I have the part number, I know they are sealed power brand.
I'll give those places a call, definitely doesn't hurt to ask.
Thanks
OK so the engine I had rebuilt for my truck had suffered a gasket/sealant failure and flooded the oil pan with coolant. Engine had at most 50 minutes of run time. So when I pulled it apart I was hoping to be able to just change all bearings and of course gaskets and be on my merry way. Now...
Mostly on topic as it deals with the head studs. Is there a better way to seal them in the block. I just had to pull my engine due to coolant contamination. The sealant I used had failed. Another engine I had used blue lock-tight but still had extremely slight seepage past one or two studs but...
Since when are the stock main bolts tty? I know the stock head bolts are. But I was under the impression that the stock main bolts were a standard reusable bolt.
I know the stock head bolts are TTY. But I thought the main cap bolts were just a standard high tensile bolt. It's definitely news to me if they are TTY style.
If you have a dedicated regulator that has a return/bypass line off of it you don't have to worry about it siphoning off when it sits overnight. You can also have it feed into the filler neck with no issues. I have a system setup like that on my stepside. Can sit for months and have no issues...
Plus make a couple bucks at the same time. Still a decent price for a P400.
He does realize you can't buy them new any more right?
I'd have to get a loan to buy it.
That's pretty cheap if it's actually a p400. The biggest thing that would scare me is not being able to hear it run. It's basically a guessing game otherwise.
DB4s can put out stupid amounts of fuel.
A competent machine shop should easily be able to make any internal parts. The problem becomes cost. It can get very expensive custom making parts. Even more so if the place has the means to digitally scan the worn part and create a new one to proper...
I bet if you dig deep enough. The company that bought the rights either makes parts for newer diesel vehicles or possibly alternative fuel vehicles. So easy way to kill off older cars and trucks is to stop making parts for them.
I wouldn't out that past any company these days.
This is depressing news. If they stop making parts for the db/ds pumps not only does that hurt the lives of our truck but also the idi ford's too. That's a lot of old iron being affected.
