hello people. bought me a renault senice bj 2003 with 1.6 16v petrol engine engine code K4M 700. in the car the cylinder head was degraded which is not a problem. seals I have everything new as well as screws head is already on it. now my problem. how do I recognize which camshaft the inlet and which is the outlet. have found only mmittig of the camshafts each two “calls” as marking. these are with the two waves with different distance. and another one more question. how do I set the tax times best without special tools? there are any markings I can contact? for helpful tips I would be very grateful.
