after about 2 years, the timing belt tensioner broke a 2nd time - lost all the hydraulics, so now the engine has a bad knock. I got a free replacement after the first one broke, but is this common? this one is Beck Arnley 024-1205, I thought this was a good brand, but not getting another! what brand tensioner will last 5 years? I have torn down this engine 3 times in last 2 years. annoying, but I guess I am getting good at it...

Also, what is a good brand for the hydraulic valve lifters? I think I will replace them as well... I replaced 3 of them last time, but others getting noisy now...

thanks!
