    Glow plug indicator on for over 15 seconds, MIL illuminates, no DTC code reports

    Went to start my '06 Silverado 2500 (LBZ) the other day. Turned ignition on and the glow plug coil light came on, which is strange for this time of year in Northwest Arkansas. Stayed on well past normal time, even in freezing temperatures. I went ahead and started the vehicle, and the coil...

    LB7: Fuel in oil? Occasional white smoke

    As a follow up on this, completed the odd (passenger side) 1, 3, 5 & 7 that were showing out of balance. Lot of work, but just taking the time and following the steps on all the posts and DIY info made it way easier than I thought. Encountered zero problems along the way and it went smoothly...

    LB7: Fuel in oil? Occasional white smoke

    From what I've been reading, if the cup doesn't come out when you pop out the injector, it's best just to leave it in. Supposed to be pretty tough and alignment must be precise. If you do, be sure to drain coolant first, once the cup pops out, the coolant will flow into your cylinder and then...

    LB7: Fuel in oil? Occasional white smoke

    Thanks Tom - I've actually got a friend with an 02 Duramax that I'd failed to check with. Found out today that he's replaced a set himself and is okay to help me out if I get in a jam. I just need to verify the issue and once diagnosed I'll be on my way to "recovery". I've got all the tools...

    LB7: Fuel in oil? Occasional white smoke

    Thanks for your feedback and the info. I feel a little better about this already. Just seems that when the dealer or a shop is wanting anywhere from $3200 to $5500 it seems like there must be something huge in it. I'm getting the feeling that it's a lot of digging and a bit of an endurance...

    LB7: Fuel in oil? Occasional white smoke

    Great, thanks. I was trying to find it and will keep searching. I was just worried because I've not worked with diesels before and a bit concerned over the high pressure fuel systems and messing something up.

    LB7: Fuel in oil? Occasional white smoke

    Probably a bit unrelated, but if in fact it ends up being injectors, I know that the LB7 injectors are buried under the valve covers and it's said to be a big job getting to them. Do folks on the forum here do their own or is it something that you need special equipment for? I've got an...

    LB7: Fuel in oil? Occasional white smoke

    Right you are about the stealer.... They've already told me it'll be $100 just to hook up. I should have had my profile in better shape. I'm in SoCal...town of Temecula, just north of San Diego County line.

    LB7: Fuel in oil? Occasional white smoke

    Thanks for the quick response! I'll give that a try tomorrow. I assume that if there is in fact fuel in the oil, that driving the truck should be severely limited...? Normally shops that have efi live or a tech 2 ??

    LB7: Fuel in oil? Occasional white smoke

    I'm brand new to the forum and searched high and low for a post/thread with this issue. Have an '03 Silverado LB7 with 67K miles. Recently began noticing occasional white smoke from exhaust at random times...normally under moderate load. The other day I was dropping off my 5th wheel and the...
