I have replaced my cylinder head on my toyota hiace 3Y petrol engine, using the correct sequence for tension on the head. But when tighting the rocker arm I can't find any information, what is the tension for the rocker arm? I have started the engine but the Tappets are very noisy? Are the tappets self adjusting, as I believe they are hydraulic.
can you please advise how I can overcome these noisy tappets
