I've used a few "Cloyes" kits from the states. Only complaint so far is the tensioner, which has twice let me down and leaked oil. Meaning pull the tensioner out and take the bloody cam cover off again to set the tensioner.
First one I managed to goo up satisfactorily, but on the second the rubber part of the seal was shreaded. Seems the machining of the tensioner was a bit rough or maybe the oil hole in the head of the tensioner.
I used an o ring temporarily while new seal was procured. Not sure the o ring was a good choice as after it seemed noisy at idle to me. Maybe the o ring restricted the oil pathway at idle.
Might try a different brand next time.
