timing belts

« on: July 12, 2010, 09:08:01 PM »
since there has not been any post in the water cooled tech in a month I thought i would take the time to remind every to check there timing belts for cracks,  most are easy to look at by pulling the cover back a little and looking for wear.  A broken timing belt means bent valves or worse.

. . . and if you see a ridge in the center of the back of the belt, chances are pretty good that the idler roller is locked up.  That ridge isn't supposed to be there!  Park it until you fix it.  And you might as well replace all the seals while you are in it that deep.

 A broken timing belt means bent valves or worse.

I actually saw a TDI, 1.9L Diesel once where the belt broke, and in the process of the valves being hit, it caught one of the valve heads, bending it, sent it up at an angle, and actually knocked the mechanical injector out of the head, destroying the actual casting of the head.   :o   Actually, I saw two where this happened, but the other one broke a motor mount, causing all the mayem, so that one doesn't count....

Like Travis said, you can put some things off, but i would not reccomend putting off replacement of the timing belt.  and, for the later cars, always do any tensioners, idlers, and water pumps while you are in there.  It ain't cheap, but it's a lot better than the alternative.    ;)

I like the timing belt kits from ECS Tuning, they contain everything you need including a water pump with a metal impeller. I had mine done and replaced the belt, water pump, thermostat, and all the tensioners and rollers and stuff.

the diesels are cool when the vlaves either go though the piston or detroy the lifter and the cam , not as forgiving as a 1.8t

30,000+ on my bug since i changed the timing belt, still looks great! Just a note might be worth the extra money to change the alternator pulley while its apart, not fun having one go out 500 miles from home  ;D
