I taken on a job, after a lot of nagging from the owner. I'm not so happy to do it, but at the same time interested in to be updated on a "modern" engine. I did a lot of engine jobs in the 70.s, up to the 90.s. So after reading a lot on the internet on headgasket, and timing belt job on a 3.0 V6, I ordered timing belt kit, headgasket kit, waterpump, and new headbolts. I also today oredered the tool kit for the belt. I was hesitating about ordering the tool, since I never needed any special tool before for timing belt job. I ordered it any way, since everybody said it was necessary. After i ordered it, I talk to a guy, and finally I got an explanation why it is soo needed, (except that it makes the job easier) There is a danger, that, when you remove the belt without the loking tool, that the cam makes a snapping move due to the force of the valve spring, and since the valve steem is so tiny on a 4 valve engine, that force is enough to bend the valve, if you have bad luck . I been only doing 2 valve/cylinder engines, and I don't think you can bend those valve steems so easily? I saw the job description here at TSL, for the timing belt, and it seem's a lot easier then what Chilton, and the note that come with the belt kit, say's how to do it. Thank's a lot for that. Any special knowledge about this job from you guy's who have already done it, is appreciated.
