Overhauling process ....

These are the 16 valve's tappet. These are the parts that causes the "Tik Tik Tak Tak" sounds early in the morning when the engine started. Im not sure if there is any spoilt, seems not as my engine does not sounds after the engine warm up. My engine head when its just removed from the engine block. It has multiple layers of carbon due to years of services.
One of the 4 piston which were removed from the engine for cleaning purposes.
The upper part of the piston. 93 indicates the piston is for 4G93 Engine. D-H ... i guess stands for Double cam.

My 4G93 condition ..

It was a hot afternoon, after i drop my fren at LCCT airport, I went to visit my car at my mechanic's garage. Fuel intake system, ignition, exhaust were removed and the engine head is ready to be removed. The valve cover were removed, the interior of the engine top looks clean and still looks very good as I've always change the lubricant on time.The top head sucessfully remove. The piston were full of carbons but its well intact.

Lower part of the engine head. From here, the 16 valves were clearly noticeable, but carbon were build up due to long term service by this engine. Black Color's valve were the intake valves, due to carbon build up, it looks black. grey colors were the exhaust valves.
My twin cam still looks shiny after years of services.
Intake port looks quite clean, but if u really look insde the port, there are traces of carbon build up within the port.

My putra's engine bay without the engine head, it looks so empty.
