have an idle issue, so have removed the idle valve to give a clean etc.

 

the pipe that plugs into the IAA

 

 

stuck my finger in there, and its got black oil in there. quite thick aswel.

 

i presume these are the PCVs?

 

havent opend up the IAA yet, but i presume its gonna be full of that black oil aswell.

 

 

know that PCVs can casue smoke etc, but has anyone ever changed PCVs and had their car smoke worse? or isit a good thing to remove all the PCVs and replace

PS the hardest part of removing the idle valve/IAA,

 

is removing the clips that hold the pipe to the valve.

 

absolute pain :headvswal

well done on doing this. my hands to you on doing this task. I have heard its good to remove them but i don't know how or the why's. Either way that must have taken some time lol

ive only taken the IAA valve off at the moment, to give that a clean.

 

havent done the PCVs yet, just stumbled across the oil in them when removing the idle valve.

If the IAA is oily/gunky, your throttle bodies will be dirty too, so give them a clean with brake cleaner or similar.

 

To remove those stupid clips, perhaps a set of 'bendy pliers' will do the trick? I've used these many, many times when working on cars. Where is the IAA btw? I need to do this too!

its on the passanger side mate, at the back of the engine, at the top.

 

easy way to find it, it has a yellow plug connected to (same as the injector conenctor)

 

 

i havent examined the contents of the IIA, but the pipe going to it is "gunked up" so i presume the IIA will be to.

 

yea gonna give the throttles a clean aswell, and check the voltage on the TPS.

 

will take some pics when im down the garage sat of it.

 

 

if the pipe/PCV is oily, makes me think i need to do the PCVs al together

pppfffft easy job... i take it off for fun.....

sorted now :)

 

car idles exelant, even after reving it stays, where as before it cut out.

 

cleaned the tottle bodies,

 

removed the idle valve/ACC/IAA.....

 

 

 

 

cleaned the terminals (scrape gunk & then WD40)

 

opend/seperated it, put few cotten buds in.

 

 

started car, was still dying. but then just turned the idle valve & was sorted after the first adjustment :)

 

 

dont be scared to turn it, no point just doing like half a turn, wont make no difference. good few turns to adjust

 

happy now, can try for an MOT :)

i presume these are the PCVs? NOT the pcvs.there close thuo but in the block the pcvs are about two inch long and screw into block ,try search TTZs of Dallas. ..

yea sorry, know where the actual valves are,

 

was refering to the pipe that goes from the PCV to the idle valve :)

the PCV pipe goes to the rocker cover, not the idle valve. the pipe from the idle goes to the compressor pipe

 

ah cheers dude.

 

i like knowing and understanding the engine more,

 

developed my mechanical skills loads working on a Z, so much to learn!

A good 'HOW TO...' here...

Bullet have you got a diagram showing how u setup your catch tank for venting to atmosphere?

Id like to do this soon.

me too possibly ;-)

these will just get blocked up again from the crappy pcv valves.

A good 'HOW TO...' here...

 

Jeez - do we edit out links to other forums now?????

the PCV pipe goes to the rocker cover, not the idle valve. the pipe from the idle goes to the compressor pipe

 

how much and where to get exhaust tape. and do you think it dose what it say reduce heat by 30%

yes they do reduce heat and u can get them in any race - tune shop . ive managed to tide up my pcv as much as i could well ive deleted them and rerouted ventilation to oct and back to the intake .wouldnt recomend to ventilate it to athmospere ...
