240SX fouling #2 plug

[jwmtx]

Hello,I've got a 1992 240SX which I bought new. It has no mods and 105000 miles. Proper main. always done. Recently it has been running very rough and the #2 plug is fouled with oil. Cleaning the plug makes it run good for about two days and then it fouls again. Does this sound like a blown head gasket or does anyone think it might be something different. Thanks very much for any replies

Sounds like you have a problem with your piston rings on that cylinder.You need to run a compression test to see whats up .

I agree with you brother, but it would have to be pretty far gone to foul the plug that quick.
