loz180691 Posted August 18, 2013 Share Posted August 18, 2013 I had a new inlet cam about 2000 miles ago and all shims set to new cam.I also had a new cambelt kit from id workz and tensioner spring from toyota. Since then I have had a horrible whirring noise when coming down revs (worse on idle if revved) followed by a slight screech from same area. I've had the auxiliary belts checked for tightness and they seem fine. I didn't do the water pump when I had this work done and from reading previous threads the screech sounds like it's a faulty pump but I'm stumped on this whirring any suggestions would be fantastic thanks Quote Link to post Share on other sites
Danza V Posted August 18, 2013 Share Posted August 18, 2013 Should really do the water pump at the sane time really so it's possibly that mate. Quote Link to post Share on other sites
loz180691 Posted August 19, 2013 Author Share Posted August 19, 2013 Yer I know just this whirring noise started straight after I had the work done Quote Link to post Share on other sites
Danza V Posted August 22, 2013 Share Posted August 22, 2013 You could remove the auxiliary belts and just run the car without them on at idle and see if the noise disappears, if it disappears then its something to with that area. Or you could check the belts for tightness, could be over tighten belts, causing a super charger kind of sound. Quote Link to post Share on other sites
loz180691 Posted August 22, 2013 Author Share Posted August 22, 2013 It was idler on cambelt only did 1500 miles and the noise got worse so sent back to id workz Quote Link to post Share on other sites
ryan lang Posted August 23, 2013 Share Posted August 23, 2013 Ahh that's a shitter, I'm sure iddy will sort you out anyway. I was just about to say bit could be the idler pulley, maybe the garage dropped it, and they are made in their thousands by machines so I imagine they'll have a few bunk ones every now and then Quote Link to post Share on other sites
loz180691 Posted August 25, 2013 Author Share Posted August 25, 2013 Ye just one of them I've sent it back for them to check it out I got a replacement from them and its spot on now Quote Link to post Share on other sites
