Morning to all, your help would be greatly appreciated. Not for my car (thankfully), but I've just got off the phone to my brother who is touring France in his 993 C2. When the car is warm and idling, he can see some blue smoke predominantly from the left bank, and the car is clearly consuming oil whcih he is topping up. At all other times, he says it is unnoticable with the car still performing fine.

He is quite concerned it may be something major, and still has to nurse the car back another 600 miles or so to get back to England. Anyone got any ideas what it might be? And should he continue to drive it back to Blighty?

Is the oil level correct? (i.e. not too high - car on level ground, checked via the dipstick, with the engine running and at running temperature.)

How many miles has the car done? (Towards six figures and the top end may need seeing to.)

It may be the rocker cover gasket, this tends to fail after a while and looks more alarming than it is. The right hand side one on mine went last year at around 80,000.

Very common on 993s - a good pointer to this is to turn the heater on when the car is moving at about 30mph. If you get a waft of burning oil smell in the cabin then the oil is on - not in - the exhaust and therefore caused by oil on the exhaust pipe or in the heat-exchanger

Thanks for the advice, I have just passed this on to him. He is 99% sure the oil is not over-filled. He is now checking to see whether the smoke is actually coming out of the exhaust as opposed to off the exhaust.

As I understand it, if the rocker cover gasket is leaking, it drips on to the heat shield, causing blue haze from around the exhaust, and not out of it - this could be the culprit as the car has only done aprox 60k miles, which would seem a little early for requiring top end work.

Incidentally Laurence, what sort of money was it to fix yours last year?
