    While the truck sits unused.. can I/should I soak the cylinders?

    There are no real issues at the moment.. other than an unknown prior-owner history, and a good number of miles (250K+). I use it as a camper. So most of the driving has been long highway runs, minimum 100 miles at a time, (with a 4:11 rear). It was an ambulance in its prior life, and it...

    While the truck sits unused.. can I/should I soak the cylinders?

    It's not so much conditioning the cylinders against time or winterizing.. it's more about having the opportunity to do a 'deep clean' on any deposits. It's often said.. 'Fill the fuel filter with ATF start it, then let it sit overnight.' (good for injectors and IP) Is there an option above...

    While the truck sits unused.. can I/should I soak the cylinders?

    I will not be driving my truck for the next month or so. Would there be any benefit to squirting something in to the cylinders (whether it be SeaFoam, acetone, trans fluid, Marvel Mystery Oil, etc..) to 'clean/soak' any deposits, clean the rings, etc? If so, how long is TOO long to let it...

    California trip anyone along the way in case?

    Frugal friend of mine swings by Indian reservations with casinos when ever possible. He said, they use the cheap fuel to get people to stop, and feel better about going into the casino with the money they saved...(and there's no federal tax). He paid 2.39 for diesel last week. (He has a big...

    High output Alternator options for 6.9 idi

    I don't know if it would be more expensive, but is there an alternator/generator shop anywhere near you that you could check to see the cost of rebuilding one (the one you have or a "new-to-you" unit), and change the output profile for more amps at idle/lower RPM's, ramp up sooner and plateau...

    Help narrowing down cause of the tapping noise..

    It's as if the noise tracks with what gear the transmission (E4OD) is in.. at 35 mph it drops a bit when it shifts.

    Help narrowing down cause of the tapping noise..

    Help narrowing down cause of the tapping noise..

    I am apologizing in advance for this being one of those.. "It could be one of any number of things" issues. I have seen threads on this before, but I would really appreciate some insight from the group to narrow down possibilities. There is an engine noise (clicking/tapping) that can be heard...
