Title: Vaccum hose replacement problem
Post by: sickboy2345 on July 14, 2008, 06:35:34 PM
ok today i started replacing my vaccum hoses
(little ******* thingys -  takes some time to get to them :] )

anyway i had some boost leaks etc - nevermind , and i think i found my problem
one of them vaccum hoses was jnust hanging there, and i havent got a clue where it could be possibly connected to(tried to track it - no joy) i have taken a pic so you can see it (dont worry about white thingys-they got numbers on it so i wont mess it up) basically the thing im holding connect to the UIM and i circled it  - i know it must go there but what about the other end?

ok the other thing is that i know that behind the circled thing (i think its called solenoid rack) there is some hoses to replace, my problem is  -i dont know how to take it off without messing it up, besides i dont know how its mounted, its got one philips screw on the front(and three at the back apparently), but at the back everything is blocked with some weirid wires/hoses - u name it, and i cant get to them(dont want to strip the head :( ) - my question is have you got your ways to get the ******* thing off?

Heya buddy, funnily enough I was out having a look at mine and i believe i can see what it connects to. it appears to go onto the bottom of this solenoid (or whatever it is) http://i323.photobucket.com/albums/nn464/Locki666/100_0207.jpg (http://i323.photobucket.com/albums/nn464/Locki666/100_0207.jpg)

Funny thing is, whilst i was looking at that for you, i noticed that there was nothing connected to one pipe on my solenoid rack (just a bare metal pipe sitting there) so i may have found what i\'ve been looking for all this time.

HTH m8

EDIT: sorry m8, couldn\'t get back to edit the message in time, forget what i just said, i was looking at the wrong part. I found the check valve you are asking about and it\'s not the one i put in the pic. sorry m8. I\'m still having a look tho, so i\'ll try n put the correct pic up shortly.

Found it m8, it goes to the solenoid marked "G" in that hoses picture
sory about the previous c**k up lol.

Just had a closer look at mine and i\'ve found about 5 bare ends! just doesn\'t seem to be any loose hoses lying around that look as though they should fit onto them :S

not all of the metal pipes should have vacume hoses on them

sorry for now hijacking your thread m8, but dave.... you say that not all the metal pipes should be connected to something? i found about 5 with nothing on, some are just metal pipes with nothing at either end, and one or two are connected to a hose one end but nothing at the other. is this normal?

ok at last i took my car for a spin today , and im not happy..:( basically i have a huge boost loss and i cant figure out why...

first i started the engine, started at the first time, sounded really good, taken it for a spin, on the first 2 gears everything is ok but when i get to 3rd i get 10 psi at 3200 then drop to 8 at about 5k and then huge drop to like 5 psi, also when i take my car to higher speed 120mph for example and then release the acceleration pedal i can hear the sound along with blow off really short high pitched sound (like if i blow up the baloon and then stretched the top of it and you can hear it screetching) its really short likek 1 second but really loud coz i can hear it over the stereo and engine.

also i dont know if its normal but when i look under the bonnet and rev it a bit i can see these two inttercooler hoses expanding like if they were breathing  - really quick like if it was blowing the air to the intercooler.


any ideas?

i want to start driving my car..:((((((
