Between last oil change/inspection @dealership (everything looked good), and the one this week, car developed an oil leak.
No oil on driveway to tip me off.
Leakage seen when car on lift-oil was being sprayed on underside. Since source of leak not readily obvious, had dye test done.
When car seen yesterday, quite a bit of oil had leaked out.
Test points to blown head gasket.
Aside from leak, had absolutely no indication there was a problem:
no heavy exhaust, no idiot lights on. The bright side is that it was caught before I broke down, killed the engine, etc.
I'm posting this mainly to vent.
One thing is for absolute sure:
I will never, ever buy another Ford.
