Right instead of asking what the tapping noise is i know its my tappets. Searched the threads and found this:
adjusting the tapets is easy so get outside and do it yourself, put the car in 3rd gear and jack the car up on one side at the front, then remove the rocker cover and spark plugs so u dont have to work against the compression. next turn the front wheel thats raised off the floor in a forward direction to turn the engine over to the correct position and adjust the valves to the following specs using a feeler gauge:
valve clearances are- 0.20mm for all the inlet valves and 0.40mm for the exhaust valves
No.1 exaust valve fully open - adjust No.3 inlet and No.4 exhaust.
No.3 exhaust vale fully open - adjust No4 inlet and No2 exhaust.
No4 exhaust open- adjust No2 inlet and No1 exhaust.
No2 exhaust open - adjust No1 inlet and No3 exhaust.
Is this correct? Just checking you see before i start taking things apart.
Also is it easy to do? I have all the tools and moderate knowledge and a brother with more knowledge
Cheers
