squeeling noise from timing belt -4AGE- ITS BACK! :(

I thought my noise was coming from the bottom of the engine as well - but its deceptive, the noise bounces of too many things. In fact i think i changed my starter motor to rule that out! But try pulling off vacuum hoses to see if the noise stops - when i pulled the hose from the intake to the breather pipe on the rocker cover it solved my problem...

I pulled the dip stick and wammo, gone, you could hear the air suck in!
