Wastegate problems ?

[Rogue]

Hello All ..

I am having problems with my wastegate.

I have stock R33.

My turbo is not boosting, the wastegate seems to be jammed.

I have removed the heat shield and wastegate actuator, and noticed that the wastegate is catching on something.

When you turn it, it will not freely turn anticlockwise until you lift it.

I had once had the exhaust manifold to turbo gasket break up .. and require fixing so I am thinking that maybe a small piece of gasket worked its way down into the wastegate inside and now this is the reason why It is jamming.

Can anybody please comment before I start taking the turbo off my vehicle.

Thanks, regards

Hm, I would have replied to this earlier if I had noticed this earlier, so my apologies!

I had a very similar problem, a sticking wastegate. I didn't know this until I pulled the turbo off and had it examined by an engineer at Garrett. He found the fault, which was it had been welded shut and later on the weld cut, which stuffed the pivot. I got quoted and paid $140 to fix it.

The best deal is to just pull the turbo off and have a look. If it's a factory turbo then Garrett in Chipping Norton should be able to fix it pretty cheaply if it's damaged. If it's just blocked with something then you can probably clean it out yourself.

man, you dont need to pull of the turbo - I had similar probs, just take off the dump pipe from turbo to cat. It only takes about an hour to remove and gives you easy access to the back of the turbo to see how the wastegate is operating clearly!!

Oh yeah I didn't think of that. Only pull it off if you need to fix it. But still, it can be tricky to get the dump pipe out of the way unless you can remove the whole thing. Mine is welded to front pipe and cat, so I don't think I could inspect it very easily with it all still on the car. But yeah, do what you can before taking the turbo off first.
