Engine Ticking Noise

[ep91starbo]

Hello, i just bought a 96 glanza V and when cold started the there is a ticking noise from the engine, the ticking noise isnt as loud after about 15 seconds or so.

Im not to sure if its the idle control valve or it might be a cracked mani.

heres a vid of the the engine bay when heated up.

any advice if its a cracked head or mani or just the idle control valve would be appreciated , thanks.

Its the idle control valve mate. They all do it. Will go crazy loud in the winter!

just out of interest what rpm is the car idling at???

On a cold start up around 1250 rpm

when engine heats up a bit 750 rpm

when the engine is warm and idling at 750 rpm, raise the rpm by 50 to 800 and see if it makes any difference to the noise.

it is adjusted by a small screw located on the throttle body. to find it, follow the cable that attaches to the throttle body round on the linkage. the linkage piece rests on a little screw with a 8mm screw on the right. sometimes marked with a yellow dot. (sorry, not very good with explanations)

i noticed that this reduced the noise from the ICV, but you will still be able to hear the injectors ticking away, they are pretty loud when bonnet is up.
