depends on where the blow out is in the gasket if that is the problem, under the head all the passages are exposed to each other till sealed by the gasket. He may even experiance a miss fire in the engine.
I don't believe he mentioned how many mile are on the motor even though a gasket can blow at any time!
He can also check his spark plugs for excess oil or run a compression check.
Blown head gaskets can affect all sorts of things. Some things may not show up to extremes till later.
It is good he found the trace this early as he can pursue the issue soon before he gets stranded some where.
Heck it mat be nothing at all
