Thanks for the replies.
I don't know the condition of my gasket as I haven't removed the rocker cover yet. I have an injector to change, which requires the removal of the rocker cover and will only find out the condition of the gasket once the job is started.
I'm on disability benefit and really struggle to get by. My Audi was a £500 car. This £95 gasket/rocker cover is a fizzin disaster are for me. I was expecting to pay a fiver for a replacement.
Has anyone got any other suggestions that may be able to help me out? Appreciated, sincerely.
