Hey guys,
I'm doing my best to diagnose my mother in-law's '99 v6 mustang.
Symptoms are an intermittent miss under load, sometimes gets pretty bad while driving.
We have ruled out plugs/wires/etc, no codes.
Leakdown test shows that #2 cylinder won't hold compression.
Her mechanic says it's a stuck/burnt valve and wants to take heads off and have them rebuilt.
I want to make sure it's not "just" a head gasket.
I don't see any oil/coolant mixing and no visible external leaks. Is there any way I can be sure of what the real problem is before dropping $1400?
Thanks!
