Short story is that No1 daughter was driving the car when something punched a hole in the sump. I've temporarily fixed the hole and refilled with oil. Engine is not seized, but despite fuel and a spark the engine turns over but will not start. My amateur guess is that the rings may have welded to the piston and the resulting reduced compression is the culprit.
Anyone got any suggestions about repairing it? Is it even worth it? It's done about 30k miles and is 4 yrs old.
