waaaaaaaaa lee chinese wastegate troubles what to watch out for

**fredio54** · 1-21-07, 5:20

so, i bought this 44mm tial knock off vband gate, and pulled it down to port it a little, and tidy it up in general. i noticed that the valve only sealed perfectly (i'm fussy, it was good enough) in one orientation, and thus, i decided to lap the valve. no big deal. i decided to make short work of it by using a power drill to do it. no big deal. i decided to turn it backwards too.... big deal. the head of the valve was threaded onto the stem :-) its welded on now, and centred better, and seals perfectly no matter which way its turned.

moral of the story, if its a cheap one, check it out before bolting it on.

in order ...
looks ok
threaded surprise
drilled and counter sunk
ready to weld
welded
ground clean

might pay to check the dodgy ones thoroughly if you buy em ;-)

Weld could have been cleaned up tidier, but it'll work all the same

Nice work Fred.

**fredio54** · 1-21-07, 7:07

its in the exhaust flow, but in a place where no flow occurs. i nearly didnt grind it at all... i assume you are pulling my leg :-)

**carcenomy** · 1-21-07, 7:16

Of course

Why are you up at this time of night?

**rebel2k4** · 1-21-07, 13:12

good info buddy... something to surely keep in mind.

**fredio54** · 1-21-07, 15:50

would surely suck if it fell off, and you got one of, NO BOOST, or TOO MUCH BOOST :-) not a problem, just a public service. the photos are on their way to the manufacturer as we speak, maybe they'll make it better next time ?

**SixSick6** · 1-21-07, 15:54

Nah, I think they'll just cane the Asian boy.

**fredio54** · 1-21-07, 18:15

it was assembled properly, the design was bad, using a two piece valve... a mate suggested a chevy valve, but i dont need it and they arent readily available here...

**SixSick6** · 1-21-07, 19:22

I get lost in the fact that you linked all the photos. Why not resize them using photoshop, then host them so you can see all of them at once?

**fredio54** · 1-21-07, 20:06

host them where? by embedding them on mx6.com? hmmm perhaps next time

its also less obnoxious to assume that ppl want to see your massive boring pics :-)

if they dont, then they arent forced to like this...

anyway...

fred.

imageshack.us man

Here I'll start you off, resized to 500 through PS:

Much better, no?

PS- nice sheets!

**fredio54** · 1-21-07, 20:09

photobucket.com man? or not so good?

**SixSick6** · 1-21-07, 20:13

Theres a reason why it's called "photosuckit". It's aight but...imageshack is the way to go.

**fredio54** · 1-21-07, 20:17

nice sheets? you mean the ones on the bed under my baby turbo, or the tablecloth? were there stains? damn. i hope not.

**SixSick6** · 1-21-07, 20:36

No I meant the thread count. Whats that 1,000 thread count?
