How To Do A Boost Leak Check?

[chriswoodfto]

hey guys, right my boost has been a bit up and down the last few days since i had aproblem with the spark plugs, diferent issue, basically i want to know a easy way to check for leaks, did some googling and a guy posted that if you mix water and fairy liquid then spray/spritz this on manifold, were the bov connects to the hose, etc etc when its reved the bits that are leaking will bubble up because of the fairy liquid. not massivly sure on wether this is a great idea as if theres a big hole i dont want fairy liquid leaking in.lol.

so anyone else got any ways of checking?

also some one told me to check my boost gauge for a leak and boost controller. how???

You will hear it

[chriswoodfto]

i can hear it,lol. i wana know were its coming from.

[DavidAshton]

Ahhhhh my appologies.

Firstly check the flange where the pipe joins to the turbo!

I had a boost leak for over 2 months spent fookin hours trying to find it, turns out it was the flange was not straight.

If that dont work

Build a boost leak tester like so

Boost leak is a bastard. Finding the fucker on a FMIC is a aload of bollocks!

[chriswoodfto]

ahh, cool. looks like a ballache but ill give it a go, lol. cool. ill have a look at the flange then, form above or below???

mine had leak on the flange that bolts to the turbo just got it sorted today

[chriswoodfto]

cool. im trying to find a place thatll do the check for me, my mechanics mobiles off at the min tho, when you say its out, by how much, am i talking mm or ..

[DavidAshton]

look at the flange side on, if its flat its ok, if its not its going to leak.

[DavidAshton]

Also cheshire, what did you do to get your flange sorted?

I took the gasket out and its ok sometimes but leaks others. Was going to try that gasket paste stuff this weekend see if its shuts it up for good.

[chriswoodfto]

sorry im not being much use here as i dont know which way the flang is sat.lol. i need to be stood infront of bumper right, is it gona b easier from underneath or stood above it.

again apologies for my stupidity.

[DavidAshton]

Nahhhhhhh your thinking all wrong

Take the pipe off that bolts to the turbo, check the flat bit that seals agains the turbo is flat.

[chriswoodfto]

cool. right im on the same track now i think, the black plastic pipe that comes up to the top left of engine,

i havent used it yet but ive got this leak detection spray from work. i think it foams up on any leaks.

[chriswoodfto]

ahh sounds similar to the water and fairy liqiud idea. im giving to the garage tomorow so they can sort it. its mekin another squeeky noise now. one i think im beign paranoid about tho. think it might just be interior plastics.lol.

[chriswoodfto]

been to garage today, he check all the pipe work for me, says theres no splits in any of the pipes. he rekons it could be the ind kit thats nakerd, also the pipes are very soft he said could be that, so to replace them for silicon jobbies.

so... were do i get all the inlet pipes from in silicon or is a case of measuring them up and ordering the apropriate bits from ebay?

whic pipes would u suggest replacing too?

[chriswoodfto]

just checkd the pipe that goes from the rubo, at the flange, its not sat quite flush as you guys said would probs be the problem, its in the garage for the clutch doing on thursday so ill get it tightened up then, cheers guys.
