Re: Have only had scooby for week and its knocking help

Hi, before this problem I was having a slight hesitation when I put my foot down and then it would clear, wife was driving it today and it started knocking when she tried to change gear it would stall. I have started the car up and it's knocking while ticking over and when revved. The oil was changed about 2 weeks ago if that helps!

Re: Have only had scooby for week and its knocking help

that's not sounding healthy at all,what oil was put in it,whats the mileage?etc..

private sale or dealer??..if dealer get it back and get a compression test done,could be either a valve or piston problem,then again it may be neither..

It screws into the plug hole. So it's the same size as your spark plug

Changing the engine is the cheapest way but you can't tell how well it's been treated in the past
