Does anyone have a prefered injector cleaner that you add to the fuel. I add standardyne, but every oil change it sure does run well after I run some liquid moly diesel purge through it.
As this is difficult to come by, is there a more generic product out there that is recommended?

The Lubro moly stuff is all I ever use in my various german cars, why is it hard to get in canada? Can your local parts shop not special order it for you?

I use "DieselKleen", available at CT: http://www.canadiantire.ca/AST/browse/4/Auto/3/AutoFluidsChemicals/DieselAdditives/PRDOVR~0380766P/Diesel+Kleen+with+Cetane+Boost.jsp?locale=en
It was recommended to me by the diesel mechanic I worked with at a GM dealership, it's what he runs in his Duramax. I add some every few tanks, and a smaller amount every tank in the winter. Seems to help, but I do notice my mileage goes down a bit if I use it every tank in the warmer weather.

its "Stanadyne"..
and i run straight 2 cycle oil in my diesel all the time, and i run some ATF occasionally to clean the injectors.
-
I have an injector that is tickin, particularly after higher speed runs.
someone mentioned to me that the injector is breaking early, and advancing the timing considerably.
anyone got any opinions on this?
i chased thru my oiling system to determine no fault found, and eventually added a healthy dose of Lucas fuel additive, and it went away, but a high speed on the way to school just now brought it back.
i had stopped waxin until my car stabilizes a bit (was gonna add wax tonight for the first time in a while)
i don't wanna take that injector out, as i had to tighten it to way over 100 ft/lbs to get it to stay in for some reason.. what damage will this cause?
i cannot wax thru the winter, so i need to know what i'm up against.

Could be opening early.
Can you elaborate thre highlighted comment?
Are you saying ther injector kept unscrewing, or were you struggling to get the heatshield to seal? Damage could be done to the head. A correctly distorted heatshield should work with 30lb ft. Are you sure it's not injector body leak, or even diesel returns leaking?
I think the injector needs to come out, and checked...
-
Really like it would begin to smoke from the threads where it was falling out.. Each time I would tighten it more and it would just keep falling out. Eventually I tightened the *** out of it and it stayed. I was quite sure I was gonna snap it clean off, or pull the threads out (or as I learned later, break a chunk of the head iff). But none of that happened. So id like it leave it if I can. It ain't ticked since yesterday

dumping stuff in the engine oil will NEVER have ANY effect on an injector..
you tightened the injector body to 100 ft lbs, or the injector into the head at 100 ft lbs?
you may never get it back out in one piece if you tightened it in the head that tight..

but it is ticking, and it needs to be fixed.. not gonna just fix its self, no matter what you dump in your tank. once the nozzle is compromised, the injector needs a full rebuild..

That's quite common, especially when your keys are hung up and you're inside the house ;D
I have never heard of an inector unscrewing itself, seeing as the fuel line nut would need to be loose. :-\. The fact that it's noisy enough to be heard above a naturally noisy engine, and chosen, it must be significant.
I feel my leg being pulled ;D
-
Hahahaha no really as it did! The injector really only has to back out a tiny bit to begin smoking.
Well, anyway, the tickin has subsided considerably. It does tick sometimes, but not nearly as much as it did that day.
I will let you know.
(it really did fall out a few times!)
-
I bet the sealing surface is corroded and isn't sealing good.
-
did you use NEW heat shields?
-
start the car and get it running till warm, take the fuel lines off the filter and put them in a jug of auto trans fluid straight. and run the jug dry. before it runs out completely let the engine sit for a few hours then hook your feul line back up and run it as normal.
ATF is a very very good cleanser.

of course it is, its LOADED with different detergents..
-
I know, that's why I suggested it. ;)

with some Xilol (like WD40) and ISO heat-isopropil alcohol even better.
I'll try next time oven cleaner anybody?

Hahahaha is he being facetious? I was even gonna do it :(
