external wastegate problem

[black_wag]

just unplumbed my external from where it bolts into the exhaust and now it sounds like a tractor like the gases are bypassing the turbo and blowing them straight out the external pipe as an exhaust. anyone know what could be happening?

[nt_a_foz]

Vac hoses hooked up correctly??

[black_wag]

i dont know much about externals but i think they are. its a vf22 and the factory internal has a bracket on it to hold the actuator closed and a hose from the turbo to the boost tap and then to the external

[Koom]

Un-plumbed your external? as in removed it? or just pulled the vacuum lines off it?

Your explanation of the problem is rather vague and hard to figure what is going on or what you've changed?

[black_wag]

it has a removable flange where the screamer pipe on it bolts back into the exhaust to run to the atmosphere. i unbolted that piece and now its blowing exhaust gases out that pipe and sounds like a tractor. havnt touched the vaccuum hose. it only has one of them with the boost tap on it

So you did block off the hole left in the exhaust from when it was plumbed in? The valve seats probably leaking bypassing a slight amount when closed.

[black_wag]

lol if you look under the car you can see the exhaust gases coming out of the external screamer pipe. mite just hav to hook it back into the exhaust and get the garage to look at it

sounds like it has siezed open.

is it a cheap one, or in old worn condition, I have seen a couple of the tial knock off's sieze & stick open aye.

have you plated over where it plumbs back into the exhaust ??? is this where you are meaning & not the w/gate itself ???

If Im reading it correct, that you just took off the external wastegate... If thats the case then yes, you need to block it off/pur the external back on otherwise you have just got urself the mother of all exhaust leaks lol

You have answered your problem in your question if Im reading it correctly. ???

I bet that he was talking to Monolith.

So you're saying that you just got your car certed/wof/running right etc etc then decided to pull the external apart too make more noise and now it's making too much noise?

And it has been asked, did you blank off the hole that is left in the exhaust?

Trying to decipher what you've left open on your exhaust, yet without you answering the question of which bit is open, its nigh on impossible.
