compression check questions/problems???
 
Did compression check after checking plugs and found one on passenger rear to be pure white(new looking) That cylinder had 180 psi!!! others on same bank were 120-130psi. Did the same on the other bank and they were all 110-120psi.
Any ideas as to whats going on here. No coolant problems and the one high cylinder in the past has been oil fowled. Car does have a miss that comes and goes at different steady RPM. Any help would be great.I thought maybe a follwer came off but how do I tell? Or possible head gasket problem.
