I missed two cases of "the old filter gasket stuck to the block".
1st time on my 72 Dodge pickup, oil puked onto my driveway, annoying but not expensive.
2nd time many years later on my wife's early 1983 Toyota Camry. She called me at work to ask what to do, she had head a noise and noticed the little red light was on, then pulled off the freeway when she could. Considering how loud she played the stereo, I knew the engine had serious problems.
I mentally went through what could possibly have caused those symptoms and eliminated double gasketing because I was sure I had checked, I even remembered checking when I changed the oil the day before.
I got home just before she did in the tow truck with her beloved Camry on the tow hook. I looked in the garbage can, and there was th old filter with no gasket
In 1983 Camrys were so new it took 6 weeks to get a new crankshaft, no under sized bearings were available yet. A crankshaft, main and rod bearings and one connecting rod and the engine was as good as new. It gave us 200k plus miles of trouble free driving after that. I haven't had double gasket problem since.
