Hi! looking for advice due to problems with my engine.
I had a problem with noisy hydraulic tappets, sounded like one or two of them, specially on cold or idle, then in one moment a very loud *tic tic tic* or *crack crack crack* came in, looked like empty or faulty tappet :/ so i replaced them with new ones, put engine together, on the first start al tappets made some noise but them calm down except that excatly same noise wich isreally loud and comes from 3 or 4 cylinder in the head. what could be the problem? tappets not getting oil somewhere in 3 or 4 cylinder? or it could be something else wrong with the head there? oil pressure is fine, the oil is new and proper :/ what should i start with?
