Hi Mark

Thanks for your reply.

I think the nosie is coming from the front of the car. It must have something to do with the cold weather because thinking about it, it didin't do it yesterday but it did it today, which I think was slightly colder than yesterday.

So, what do I do now if its these injector things? What are injectors?

Put it this way, I went into a shell garage and asked for SHELL 710 as it was on the oil cap. They didn't know what I was talking about so they came out to check. After they had finished laughing themselves silly they explained to me that said SHELL OIL and the OIL was just upside down!!!

So, as I said please tell me what to injector fluid get, how much to get, any particular make and confirm that I just shove the whole lot in the petrol tank.

Thanks
Jo
