Default Re: Chasing the knock.

Agree with Farrell in Vancover. The engine is old, dirty and the knock is substantial. You can dick around with various things piecemeal for a long time trying one thing at a time. My personal opinion is that the noise is not coming from a fibre camshaft gear, although it may well need to be replaced, or not, depending on measurements. The photos are inconclusive. The fibre gears rarely make noise like that. Tear it down and do it right. The car is really good looking and deserves a good engine.
