hi all,

is it really necessary to change the timing belt idler and tensioner bearings when the timing belt is changed? i just got this 626 with 100,000 km on it and i don't know what the service history is. so, in addition to the usual stuff (spark plugs, engine oil) i also want to change the timing belt.

mazda sources sa web recommend also changing the valve head cover gasket at the same time as the timing belt. and the 2 bearings along with the timing belt. unfortunately, according to my canvassing (over the phone) this will cost a lot! e.g.

timing belt - 1800 lowest price (OEM)
idler bearing - 1800
tension bearing - 4650
valve head cover gasket - 1800

and wala pa diyan ang labor! :sad:
ang labas mas mahal ang gagastusin ko kesa dun sa B1 engine ni kiaDOHC sa protegetech!!

O.T. di pa rin na-a-approve ang membership request ko sa protegetech. tulong naman.. ;)
