Glanza_Ragger Posted February 12, 2006 Posted February 12, 2006 Hello chaps, second post here so be nice to me..If i let it idle is sounds fine.As soon as i let the revs rise above idle is has a knocking sound from the top of the engine bay nearest the scuttle pannel As soon as it passes say 1500ish, the noise goes completely.It happens when im pulling away in 1st or when im just sitting still.I honestly havent got a clue on this problem.It just suddenly started making the noise yesterday morning when i started it.Help? ill also be getting some pics of my engine bay up once i find some batterys.

scutch0 Posted February 12, 2006 Posted February 12, 2006 does it sound like its coming from the engine itself, (if so where abouts) or something close to the engine?Rich. Quote
Glanza_Ragger Posted February 12, 2006 Author Posted February 12, 2006 does it sound like its coming from the engine itself, (if so where abouts) or something close to the engine?Rich.It sounds like its comming from behind the speedo / around the throttle body area but its hard to tell with out somebody sitting in the car keeping the revs up for me to listen Quote
DAN_GTT Posted February 12, 2006 Posted February 12, 2006 well if you stick your hand under the top mount intercooler you will be able to control the revs by moving the throttle butterfly, its on the inlet manifold. Bloody hard to explain lol. But stick your hand under there and you will feel it Quote
DAN_GTT Posted February 12, 2006 Posted February 12, 2006 Also is it more of a tapping noise than a knocking noise? Quote
Glanza_Ragger Posted February 12, 2006 Author Posted February 12, 2006 Also is it more of a tapping noise than a knocking noise?lol i would move the throttle butterfly but i cant get my hand under there, fat hands it sounds as if its comming from the boost control valve area, the boost guage needle is also flickering up and down whilst its on vacum.. im baffled.And no chap, its not a stray cat.. could be my neighbours pup though any suggestions as to what it is?If not ill nip it to toyota tomorrow and have to fork out for one of there gimps to look at it !

paulgtt Posted February 12, 2006 Posted February 12, 2006 have you got a dump valve on it? my boost gauge used to flicker around because i hadn't blocked off the recirculating valve properley. Quote

DAN_GTT Posted February 12, 2006 Posted February 12, 2006 If not ill nip it to toyota tomorrow and have to fork out for one of there gimps to look at it !<{POST_SNAPBACK}>Nope sure you didnt Quote
starletboy Posted February 12, 2006 Posted February 12, 2006 no sorry mate not you they guy that has the problem with his car!!! Quote
paulgtt Posted February 12, 2006 Posted February 12, 2006 alright mate misunderstood.....it happens a lot with me Quote
Glanza_Ragger Posted February 12, 2006 Author Posted February 12, 2006 So in other words, nobody has a clue? And yeah i have blocked off the old line.It was fine untill a couple of days ago. Quote
paulgtt Posted February 12, 2006 Posted February 12, 2006 well it could be the idle control valve, its a small plug at top of engine near the brake fluid resevoir. pull it out when engine is running and tapping should stop but engine will stall after a few seconds. mine taps regular and have been told its summet to do with the induction kit but i don't know for sure.

shelly_star Posted February 12, 2006 Posted February 12, 2006 got the same problem mate, people say it's common for the starlet, the mechanic didn't have a clue what it was and didnt know how to get rid of it! oh my goodness. Quote
shelly_star Posted February 12, 2006 Posted February 12, 2006 forgot to say, welcome to the club buddy. Quote

I was going to try the idle control valve tomorrow morning when its light outside and i can see what im doing Thanks for the serious suggestion paul.And thanks for the welcome shelly, good to be on here finally after having my glanza for over 4 months now the noise does actually sound like a clicking from some type of sensor or valve more than an internal knock.Ill yoink the plug out tomorrow morning and if it stops ill have to get a new one.Ive just finished fitting my samcos so ill get some piccys up in the morning guys Quote
Ryno Posted February 18, 2006 Posted February 18, 2006 just noisey starlet injectors! nothing to worrie about! is it like a quiet tick'a tick'a tick'a tick'a Quote
Glanza_Ragger Posted February 19, 2006 Author Posted February 19, 2006 lol no offence to any of you toy'mota mechanics, just a few at my local place are idiots. any way its sorted now, thanks very much for all your suggestions. it was a shagged idle control valve. new one £10 and voila jobs a good'un ;) Quote
