Just to verify, to make sure it is the tappet problem I am having.
Is it sort of a clackity-clackity-clackity noise when the accelerator is pressed?
If I rev significantly when I start the car it fades out, but occasionally comes back while driving.
Its louder when it is cold.
Is this most likely tappets? I have had it for a while, but always assumed the tappets.
