Another question for you all. I have 3 trucks my boss asked me to pull and do all 8 injectors on. I plan on doing my own as well. These are fleet trucks and we are just going to go with premium rebuilds from rosewood. I plan on doing 1.5's for mine.
The reason we are doing this these few trucks have a sticky injector issue. We have taken them to a very respectable diesel shop here in CO, and were told the injectors are sticking untill the motor warms up, He has told us the same thing multiple times and he thinks its time for injectors due to the tests done on the injectors.(Front Range Diesel) I'm sure there are many of you who have experienced this... especially in colder states. The issue has continually gotten worse over the last couple years on two of the trucks. The truck will run on 7 out of 8 cylinders untill it warms up a bit and then it runs excellent. Its like a switch flicks and your back to normal. Happens every morning with mine within the first 2 miles leaving the house. Hold your glow plug and relay/vc gasket comments. All our trucks have brand new OE Motorcraft GPs
and VC gaskets w stancore relays.
One of the specific trucks sounds like its almost 3 cylinders down when cold. Its almost impossible to start in the cold, and typically takes a consistent jump to keep the batteries in check from cranking and cycling the glow plugs. It is much easier to start when plugged in but still is a bear to get running. Blows white diesel when cold too. Compression test on all three are well within spec when warm, and the smoke is diesel not oil. It will warm up after idling horribly rough and once warm it idles perfect, and it tows like a bat out of hell all day. Pretty sure they are the factory stock injectors at around 220k.
Anyways I will be pulling them and sending them to Jim at Rosewood. I have never done business with him, but from the sounds of it he does top notch work. I personally have never done injectors on these trucks and was hoping you all could point me in the right direction to a thread that has pics and steps for removal of the injectors. I have done glow plugs on all them, and that was easy enough, just have not done injectors.
I wanted to check with you all who have experienced this problem what the solution was for you. With brand new batteries, starter, and oil change the truck experiences the same issue. The GP system is brand new which really points me to injectors... It runs great after a half hour of hard idling to bring the motor up to temp and then the injectors free up and it idles smooth and run like its a 100 degree day out. Like I said he is not sure if the injectors are stock from the factory or not, but I have a feeling they are. I'm not really sure how to tell either.
So in resolution:
1. I need a link to detailed threads on how to replace injectors... I heard you can hydro lock and bend a rod, and will be in deep #### if this happens!
2. Any advice on what else it may be before I send them off... He will loose his #### if I charge him for a set of injectors and the truck still won't start and idle on a cold morning, even when plugged in. I'm only doing one truck at a time.
Thanks in advance!
