I assume the machine shop magnafluxed the entire head. What did the intake gaskets look like? Could you have sucked coolant into the right bank from a bad intake gasket?
Drain the oil out and see if there is any antifreeze in it.
You are on the same track as my Dad. He said if the head checked out fine it could have been the intake gasket. Wonder if I should pull the driver's side head just to be sure it checks out as well?
