I wish you all the luck, my only point to posting that info is make sure you find a GOOD tech to work on it. The dealerships will put any monkey on a truck to make a quick buck

This maybe a stupid thought, but did the lly top end swap ever cross yours guys minds after that many injectors sets?


LOL thats what we are most likely going to do...

As it turns out I was contacted by a rep at a dealer we baught our LML at this morning and was told that they are looking into a possible injector replacement on both banks. We were there looking at a reg cab long bed LML yesterday as a local use truck, and they know of our old LB7 as it has been in the horse show western and english for several years (big businuess around here). They asked how it was doing and braught up injectors.

There are a couple fellas on here who have done it. I have seen LLY heads on ebay fairly cheap. With some quick math I am betting you could do the swap for around the same price of an injector replacement, maybe cheaper with some good shopping.

The issue with the swap is, well the heads are off I should stud it, hmmm... I'm studded now how bout a bigger huffer, more fuel and on and on...

Well when he quoted the price on injectors he said he though they were around 150 a piece, I know that is way to low and he even told me that seems low but he didn't have the catalog in front of him. I'm guessing after labor this will be close to around $3500.

I would not let him use any crappy $150 aftermarket remans. Partszoneonline.com sells factory Bosch remans for only $45 more.

Cracked bodies

but my question is how are the bodies cracking that fast over and over, i know some people go 100-200k on a set (150k originals myself)and others like yourself are barely making it 20-40k on a set, i know nobody knows the answer but if you went through that many sets so close together i would think there has to be a reason :confused:

Haha yeah definitely!! I would go ahead and stud it while its disassembled as far as the huffer is concerned there is gonna be two of them before too long

My question is the same as yours... I wish GM or Bosch cared more to know, but this dealer seems to want to see what the issue is

Im now gettin a diesel smelling dark colored coolant in purge tank, people hate me at stop lights... But it is handy to have the smoke screen up while we are doin hay mosquitos are minimal

I would prefer to hear my head gaskets are going out, instant reason to upgrade to LLY Heads

There are guys who have never switched injectors at and over 200k but I'm not one of them. There is an 02 with 235k miles or so never had injectors done but his cp3 bit the dust. I believe it is a luck of the draw kind of deal.

All my issues are not GM/Bosch related poor techs account for half of them
