I dont drive my truck very often (maybe 3-4K a year) but I have been having issues the last several times I have driven it. I have experienced inconsistency in the temp gauge fluctuating to extremes, or not heating up at all, rough idle when warm, slight knocking and coolent spewing out of reservoir. Please note, I did not experience any white smoke at start up, coolent in oil, fuel in oil or tough starts. However, I did take a balance test on the injectors and discovered they were in need of replacing even though I had them installed 30K ago.
I took it into the dealership to have them replace the thermostats and an overall check. Received a call stating that the truck was holding temp but "heated up very fast" and also a PO308 Misfire #8 code, which lead to a compression test. Test came back with high compression in #8 suggesting a failing head gasket. Now they are testing to find out if it is the head or the block and i have also asked them to perform a balance rate test to confirm my scanning tool works correctly.
I love this truck really dont want to get rid of it. I'm hoping for some helpful responses from the members of this forum. I have the following questions:
1) This same dealership replaced all my injectors and performed the head rebuild just 30K miles ago (5 yrs). I'm afraid to trust them again, I know this is going to be painfully expensive as it was the last go round.
2) Any suggestions on how to get the dealership to work with me on the cost? I really went the extra mile on the last time to prevent another headgasket issue ( new heads, HD heasd gasket, new injector cups, sealed the cups beyond the "O" gaskets). I know that standard warranty is 12 month or 12K, but this is something that should last 10 times that amount of time. I feel that I have a legitimate complaint, just not sure how or who to present it to.
3) How much labor am I saving by replacing the injectors while the head work is being completed? The injectors are just out of spec but I think I should bite the bullet and purchase new. Although, I don't want to install yet a 3rd set of dealership injectors, they have been proven to be unreliable.
4) Any suggestions of a good , reliable Diesel Garage that is familiar with the LB7 motor in the Seattle area?
