External Wastegate Broken?

[rb25debt]

I don't really know much about this, but when i hit boost, the gate opens almost instantly and i make no boost. I took off the external gate (unbranded) and realised the top part that has the diaphram in it can spin where it connects to bottom one? Time for a new gate?

No point asking for photos on this one.

umm is it me or is that a big ass crack next to the valve seat?

i just checked and It doesn't seem to have any cracks, the top bit can spin, im assuming that its not meant to do that?

The "crack" is just a casting mark.

I wasn't actually serious about asking for pictures. My comment was more along the lines of.....if the housing spins and you can't see why, it's probably broken enough to throw away.

Ahh i see haha, sweet bro, so you reckon its time for a new one?

[GTSBoy]

Probably. Look for missing fasteners. Screws, c clips, pins, whatever.

try jamming it shut and drive the car gentle towards the boost threshold area and see if the turbo is spooling up...

btw, does the car have a proper turbo on it? or is it some dim sim spring roll special with dumplings from eBay?

weird failure... how about the movement in the actuator? Is it moving normally?

I haven't checked the brand as i only just got the car, its a t3/t4 so probably a chinese one

T3/t4 also makes no sense.

Look into getting a decent turbo.

You can test a wastegate easy enough with a pump, you'll have bleed past the valve, but should be lifting off the seat if it's working and the diaphragm is intact.
