Style chooser

Hi Guys,

Got a 1.6 MIVEC for my Wira some time ago. Engine has been giving problems ever since. Hope you guys could contribute your advice on how to solve this problem.

Noisy Tappets. One mech said it can't be adjusted and I have to change them. Another said they COULD be adjusted and tightened. A third mech said they're hydraulic, so it could be that i'm using a wrong type of engine oil. Currently using a crappy 5W-30 grade oil. What do you guys think?
