icv guide on blacktops (early mk1's)

  1. #1
    theres no guide on idal control valve location on blacktops so heres a guide on were to find it
    the other guides are for silver tops and are totaly diffrent

    the icv is located
    on the drivers side of the engine below the first inlet port the/injector/sparkplug

    you wont be able to see much of the sensor but the 3 wire plug is visible
    also you can follow the vacume pipe that goes from the trottle bodie to the icv

    in the first pic the arrow going don points to the icv location, the top arrow shows the vacum pipe that leads to it



    close up pic shows the icv (circled) and i have drawn a arrow to the same vacum hose to help show were the pic was tacken from



    going closer but pics from side of bay heres the sensor(circled)



    this is the closest i can get a pic, the icv is held in place with a large rubber band, undoing the vacum hose from the tb will help get it out
    (wont move if the hose is connected) just unplug the sensor and hose and pull the icv towards the passenger side(you will have to do somme of this by touch as you cant see it propley), then you will be able to follow the last hose back to airbox(mine goes to my raceland) and disconect it



    you dont need to remove anything other than your induction kit/airbox(to get your arm around the inlet manyfold)

    make sure that when you remove and refit you havent knocked any vacum pipes lose(theres a small pipe with a t join infront of the inlet manyfold that came of easy on mine) or it will run like shit

    hope this helps a few people out as its asked a lot

    will be linked to my other guides in the stickys

    no prob mate,
    do you have the baffel inside the rocker cover, its a long steel plate it stops the oil hittting the breather

    Yeah m8 i do , it was fine for a few miles then when i next checked it was all over my engine and the mini breather was soaked with oil , where as yours is clean as a whistle.
    Is it possible ive fitted the baffle plate the wrong way up when ive changed the rocker gasket ?!?!

    its been fine for about 3000miles so far, you could try reitting the baffle, if that dosnt work try changeing the oil filter, the oil filter is what controls oil pressuer, and yours mite be alowing to much oil presuer, oil shouldnt come up the pipe/breather or it will go in to the tb

    I bought a oil catch tank because of it spilling all over and it still ended up spilling out of the can through the filter lol. I have no luck.
    But the pipe was bent over from the rocker, so can a bent pipe from rocker to catch tank cause too much pressure to make it flow out of the catch tank breather filter !?

    can here a sound of air sucking in around this location on my blacktop.
    can not find where it is sucking, i know there is a leak somewhere as the idle isnt good. has anyone else had this problem?

    I have this with my Pug XSI, which I think is pretty much the same engine, but cant seem to find the leak. Mine idles a little lumpy

    it will be a vacum leak, theres so many pipes and it only takes a very small split, only way is to remove each pipe and check very closed for probs

    lets see if this helps guys a quick rewrite

    ok for some reason the blacktop mk1 vtr seems to be hard to find any info on so 1st up thanks to 666 for this shame the pics went down but i figured it from this

    step 1, remove your airbox - reason the pipe coming up behind it and into the top section on the right is the return pipe from the ICV



    step 2, locate the icv and connecting wire needs removing do this by finding your map sensor (top left attached to the firewall behind the engine) follow the wire down just behind the first injector and youll see an odd cylinder shape with a yellow connection on it thats your ICV



    step 3, remove the ICV pipe from the throttle body housing, follow the small pipes coming from the map back to the housing, next to them is a fatter pipe this needs to be uinclipped and when you remove the icv youll need to persuade this pipe to move down through the injectors

    steps 4, get your hand behind the engine and push the icv accross so it slides of the rubber band its held on by, easiest way i found was to pull the pipe from the airbox end and push the sensor and in 5 mins youll have it off to clean or replace



    thats the offending piece, carb cleaner and earbuds works well if your getting idle issues and random revving up, sucking air like its choking ect this be a good place to begin
