i finally got off that bolt on my engine mount! oh my god i am so happy right now! i got off the upper engine mount and took off the top of the engine and now checked my valve clearance and the middle valve of the intake valves is tight! so thats my engine problem! im so happy right now. now i just need a little help on what i need to check and look out for when i really start to change it. i know how to do it im just a little confused on what to look out for on the cam chain tensioner. and also about the half moon clips. so is there anything else i need to look out for or be aware of when i really do start to dig in? thank you guys you have helped me a lot so far..
