Just a quick note... I would bet, like mine, the oil filter housing gasket and oil cooler gasket are leaking onto the belt, so might want to look into doing them as well.

I'm doing the belt, tensioner, idlers, and both gaskets at the same time in my video, so if you are up to the task I should be done it by the weekend.

These are all the parts I ordered.

i did all that also too, exactly,

and oil from oil filter housing seal ruined belt, carwashed exxon valdez front of motor so ftp pulley and belt kit easy job,
that was first repair

oil filter housing o ring service, manifold has to come off for that 1 bolt under first runner.n55

then looked at grunged out intake runners in head vavles were all shrouded in carbon and chambers nasty,from oil vapor so i walnut blasted while apart and installed new intake manifold orings gasket seals also ftp 14 bucks Rein brand

vanos sensor o rings were leaking also from heat too, new vanos came with o rings

cam timing sensor had a leak also new oring dealer 85 cents

and it came back to ac clutch bearing rough @75k ,
hub bearing noisy out of spec ever so slightly. making a squeak when hot.

Hub bearing kit Also came with and replaced new clutch hub rubber bumpers and new hub bearing could have been removed and replaced , grind off 6 small stakes retaining bearing. bumpers had small dents in them

but the kit was easier, reused old compressor hub and just put new rubbers on it from kit

so far no more squeals
front of engine dry finally no leaks
