Some pictures that i took during the process. My mechanic first checked the condition of the cylinder head and then cleaned it with special chemical to take out a of unwanted stains , debris and old engine oil from the cylinder head. Picture below.
After that, they install all of the parts back in the cylinder head. Next, they checked the valve clearance between the head and the piston by putting clays on top of the valve pocket. Sorry forgot to take picture at that time. This is a very important step because if the measurement is not accurate, the valves might hit the piston especially when MIVEC activate.
Since i'm out of budget at that time, i have to cancel my plan to port & polish the cylinder head. But nevermind. Maybe next?
Thats all for now. Wait for the next post. The finale. Thx guys!
