Some good advice but I hate to say the most sensitive component has been missed, if you have a pre cat Lambda sensor it's very sensitive to oil, post cats are normally fine as the cat will burn off most of the oil and the amount it won't burn until it's hot will be trapped. I have seen quite a few cases of turbo seal failure where the oil went through the engine and the driver kept on driving ignoring the smoke to get off motorways etc. and the pre cat sensor normally gets stuffed. Nothing you can do about it, they/it (you don't mention the model or year?) will be fine or will need replacing. If the MIL (check engine) light does not come on when you take it for a blast buy a lottery ticket as its your lucky week.
