1996 Toyota Camry Pricing and Specs

Check that the engine-oil dipstick is seated in its tube correctly. If it's not, this could be a great place for oil to escape and become plastered all over the engine. It's the small yellow, plastic loop just below the oil filter. While you're there, check that the oil filter itself hasn't come loose. Try to tighten it by turning it by hand clockwise. If it moves at all with hand pressure, it's loose.

The most likely culprit, however, is the rocker cover gasket. If this seal breaks, oil can be free to migrate out of the engine, right down the side of the cylinder head and crankcase, making the mess you've described. To check, clean the engine with degreaser and water until all the oil is gone. Then take the car for a decent drive, open the bonnet and the source of the leak may be very obvious.

Contrary to what you’ve been told the 195/70 R14 is readily available and is perfectly roadworthy for your car, falling well within the requirements for load rating and rolling radius. There are a number of brands available, but the Michelin is one of the better ones.
