    Help! Just finished the ofh port with extra crush washer and replace front balance shaft seal. Now I have this whining noise. Couple of theories.

    Balance shaft tensioner could be too tight
    Something rubbing on tbelt cover

    I didn’t touch the timing belt. Just pulled the balance shaft tensioner and sprocket.

    Thanks
    Tony

    Can the front balance shaft be out of phase? I don’t think it can but I’m not sure. I could have rotated it putting the new seal on

    Think the water pump pulley isn’t on correctly

    Ive seen outter half of WP pulley installed backwards more than once......apparently its a very easy mistake to make.

    My current GSX came to me this way and it took me awhile to actually spot it.

    Yeah real easy when you’re not paying attention. Glad that was it.

    That happened to me LOL, took me trying to put the belts on to realize that something wasnt right. I hate working in that small area to change a pulley.

    I was indecisive about taking the mount off but I said f it and left it on. Probably would’ve taken the same amount of time either way. I consider myself a pro at taking that pulley off. :aha:

    I left mine on too. I got got a long 10mm and just spun the pulley which either loosened or tightened the bolts. Then I got the belt snugged up and then tightened them down. They arent to spec but I couldnt get my torque wrench in there. I dont think its going anywhere though.

    Yup. I like to torque down certain things to spec but there’s no way to get a torque wrench in there. Just tight with a lock washer and it’s not going anywhere. Think they’re 15 ftlbs IIRC. I got a set of ratcheting wrenches from advanced on clearance for $35 :sneaky: a while back. One of the best purchases I’ve made as far as tools go.

    I got a set for when I changed my intake manifold back to the stock one. Couldnt get in there with anything else underneath and even with that it wasnt that fun.

    Nope, out came the strut bar, fuel rail, cruise control and sticking my hand in an area the size of a coke can.
