I tried doing a search but couldn't find a solid answer. I have a 92 X with 157,000 miles. Tonight I plan on seafoaming the engine through the brake booster to remove carbon buildup. I was wondering if it is a good idea to put some in the oil as well? I can't find a definitive answer so please post if you have had good or bad results with this technique or whether or not you think it is a good idea. The X runs great besides a pinging at highway speed and it also burns/leaks a quart of oil per 1,000 miles. I am afraid of clogging oil passageways but I also would like to clean up any gunk as long as it won't harm anything. Also would it aggravate a leak? If I do put it in the crankcase I would just let it idle for 5 minutes and then let it sit for a little while. So is it a good idea or a bad idea to put seafoam in the crankcase? Thanks, James.
