After my car was making a knocking sound (only sometimes) at startup for a quick second or 2 then disappearing, i have dropped it off at the garage who said he has removed the rocker cover and said my camshaft is wearing.
my question is, if it only knocks sometimes would it be the camshaft? I know that if i was travelling at 50mph in 5th gear and put my foot down the car would slightly judder then pick up.
I have been quoted around £880 + vat, for camshaft / cambelt / hydraulics & water pump.
I just dont want to be paying this much if it's not said camshaft
