240SX #2 cylinder-Seafoam

[jwmtx]

The #2 cylinder is fouling the spark plug. I'm told that it has a stuck ring or rings. Does anyone see any problem with pouring a couple of ounces of Seafoam in that cylinder and letting it soak over night. I'll do the regular seafoam treatment later. Thanks for any opinions. James

I don't see any problem with it as long be sure and spin the engine over with the plug out to get it out of the cylinder after it soaks.

Thank you, Money pit. James

No problem brother!

You should change the oil afterwards. If you do have a ring issue then a lot of seafoam will run down the cyl. walls. It can thin your oil and you shouldn't leave any solvent in your oil system.
