Bad set of injectors?
I recently purchased some casserly 190's in november and had some issues with them. I started at thread a while back about it. Basically I was driving on the highway and all the sudden an injector started missing and the truck threw an injector low circuit code. The next day I pull the injector and come to find out that one of the two bolts that hold the solenoid on top had come out. Casserly sent me another injector and all was good. Well, about a month later it did it again except in a different cylinder on the other side. I call Casserly and asked him if he could send me a new set. I dont have the time or resources to risk this happening again and he understood and sent me a new set. Installed them and the truck is up and running fine except there are some differences on how it runs. First off, it is a lot less smokey than the first set. On the first set he sent me, I had a hard time adjusting my fuel pressure. It would idle at 55 psi and would rise up to around 68-70 when I did a hard acceleration and drop to 55 at WOT. On the second set he sent me, my fuel pressure is constant at 55 while driving around and will touch 58-60 on a hard acceleration. I've only done 1 WOT run and it was a very short burst and my FP was at about 55-57. I find that very strange and I made absolutely zero adjustments to my fuel pressure settings before installing the second set. Another difference is the way it starts and what it does when I let off the gas and let the truck roll. It's hard to explain, but when you start your truck it fires and you hear the clack clack clack the diesel engine makes. On the first set, the engine would almost lope for a split second right at the start and the idle normally. It would be like clack, pause, clack, pause, clack and then idle. On the second set, it starts just like it did when stock. As for the letting off the accelerator and rolling, the first set would do something similar to starting it. Say I was coming up to a stop light and rolling into it. There would be pauses between the clacks and they werent evenly timed meaning that some of the pauses were longer than others. Now it just sounds like a normal idle. Anyone ever heard of anything like this. Casserly told me that he thinks the problem is that he put the wrong kind of locktite on the bolts that hold the solenoid down. Do you think its possible that he got my order mixed up on the second one and sent me a different size?
