Good afternoon, 

 

I have bought a Jaguar S type around a month ago. Last week I was driving and there was white smoke coming from under the bonnet. All that time I had no problems with the car. It drives brilliantly. I left my car a week for what it is, it started immediately but within seconds there was white smoke again. Anyone any idea what it could be? 

Hi Sharon,

It could be steam from leaking coolant. Have you opened the bonnet and seen where it's coming from?

Similarly, it could be oil dripping onto something hot like an exhaust manifold.

You best check it before damaged is caused.

Good luck, Russ

 

The intake flap gaskets are prone to leaking and drip oil goo onto the exhaust downpipe causing smoke on startup. They are accessed at the back of the inlet manifold casting. Gaskets are available from eBay, don't get the electrical connectors mixed up. This advice is for the V6 petrol.
