Well, in that case they are all opening around 1500 psi, which is about 110 bar, but, the spray is off to one side and there is a thick stream coming out of the center. (Well thick enough to noticed beyond the atomized fuel. And sometimes they don't spray at all right away, but they have that same stream coming out before the atomized fuel gets out!

So I've come to the conclusion that the injectors are tired, and I will had to save my pennies to buy a new set.

I wish I could find someplace that sells the pintle and body to rebuild the injectors, since I can set up the opening pressure.

It just seems weird that this came on so fast...Oh well, I hope the fuel spray, (since basically its pushing raw fuel into the prechamber) doesn't affect piston temps or anything. Or, hopefully it won't have any long term affect on the enigine.

My old engine in the car did the knocking for about 30K miles, I could never figure it out before, but I also didn't have this forum then!!

Thanks Peter for all your help, I'll let you know how I make out.
