回複：計劃DIY換timing belt, 請高手指點

Timing belt job is kind of engine model/brand specific. The first thing you need to tell others is your CAR(model year, etc...) when you ask for this type of advices. With your car model in their minds, they can give you lot more specific advices, I believe. I did mine (96' Accord) with a great deal of help from a friend here ID'ed "hardtofix" 2~3 years back.
Good luck with your project.
