hey whats up ya i havent talked awhile on this forum. but i was wondering if ya know what could be this problem. my motor in my 84 subaru was running real rough. so i started to pull spark plug wires and sure enough when i pulled 2 and 4 the motor didnt change in anyway. so that would mean the head gasket is bad right. it is an ea81 motor. ok thanks for your info

Doesn't seem like it.

 

Bad plug wires? Bad spark plugs? These 2 cylinders bad? Why would you think head gaskets?

 

Head gaskets result in lower compression, maybe coolant in oil and vice versa.
