[QUOTE=chazza;1678469]Buy yourself some engine oil detergent; the sort that is designed to strip gunge off rings, etc. I swear by Cost Effective Maintenance and Nulon - Google them.

You will need to do an oil change and change the filter as well, probably during your trip, unless you get time before-hand.

I don't think that 10 psi less on one cylinder is anything to worry about but clearing the rings etc. will make it run at its best,
