Hello pfcheintzy15
The first step to fix the problem is to remove the 2 spark plugs.
If the plugs are fouled, check oil level.
The most likely cause is worn valve guide seals and/or guides, but worn rings and cylinders can also allow oil to enter the combustion chamber.
If spark plugs show heavy whitish to brown deposits,this may indicate a coolant leak
either past the head gasket or through a crack in the combustion chamber.
The last one is most like because of 2 adjacent cylinders.
Pressure test the cooling system to check for internal coolant leakage.

If the problem still persist, have a compression test done in the two cylinders.
