Well, I did it... finally broke down and bought two bottles of Auto-RX. I have a '55 Studebaker with a '63 engine in it, it is actually in pretty good shape, runs well and holds good oil pressure, doesn't smoke much either, but I have two problems. First, the front main seal is bad. Bad as in I'm losing a quart of oil every 100 miles or so. Second, I'm getting a decent amount of blowby, enough that it fails the dollar bill test when significantly above idle (yes, it is a PCV engine.) I suspect one or more stuck rings, which is why I'm contemplating this treatment.
Should I put the Auto-RX in now, and hope that it stays in there long enough to do some good, or should I change the front main seal first? I'd rather do the Auto-RX first as I was hoping to do a cam swap at the same time as I have the timing cover off, but if it won't do any good in, say, 4-500 miles it will be money down the toilet. But I'd rather break in a new cam with otherwise clean oil, if possible.
I don't really expect the Auto-RX to fix the front seal leak, as it's a felt seal, not neoprene.
Any advice from those more familiar with this product and its uses would be greatly appreciated.
thanks,
nate
