[Ramblin Fever]

I know I've been looked at, or at least I feel that I am, paranoid when it comes to using "anything" other then oil in the crankcase.

Seals, aside from the headgasket, are the least of my concerns - with that stuff, I'm more leary of breaking off big junks of anything and sending it to clog the oil pickup screen. There's no guarantee it'll all come out with an immediate oil change following, either.

Many are not having any problems, but I've heard Sea-foam and others being refered to as mud-bath, or something similar to that effect. Where they release a lot of crud within a short amount of time, only problem is, even if you're not driving that truck and just letting it idle, that "crud" is cycling through the bearings and what ever else.

I did it twice, won't do it again. My take is it didn't accumilate overnight, and therefore I don't want it to "clean" up overnight either.

I am however, going to run a high detergent synthetic oil with a few really close OCI's for a while. Yes, I stand the same chance, i.e. something clogging my pick-up screen, but at least I know it's not thinning like water - that Sea-foam really THINNED out, much more then I had thought it would and after the 1st time of having driven with it for 10-15 minutes, I can see why others only stated that they idled there's.

I can only hope with having done every 3K OCI's, that my engine has very little crud inside, hopefully nothing to worry about.
