Seized Wastegate

[96RS4V]

righto, so i got my stag serviced yesterday (as per warranty requirements) and had the shop do a proper inspection on it - i'm not sure the last one did. so i've got a fair old list of things to fix now. or an excuse to upgrade, i'm not sure yet. there are a few items on the list that might as well have been printed in small dollar signs like oils leaks around rocker cover, steering rack, diff housing, and aircon pump. but its the seized turbo wastegate that has me a little confused.

i have noticed that my stag is more sluggish than normal but i think it was more of a gradual decline, so now that it's been brought to my attention its really annoying me. so basically i get how a forced induction system works and the role of the wastegate in that, and how if its stuck open, the pressure will keep bleeding out. But having never actually seen one, is this a repairable item? also, seems a little odd for it to seize, would it be more likely for the solenoid to be buggered instead? the reason i ask, is that i presume the solenoid can be replaced and would rather replace that than start out having extensive work done if i dont need it at the moment.

cheers

ask if you can just replace it, 32GTST wastegates are ~10psi and <$100au

Rb rocker covers love to leak

During my turbo probs I noticed leaks round the rocker covers. Screws were about 1/2 turn loose. Will wait ansd see what happens.

i saw for around 60, i just said under 100 as a guide

that's actually the wastegate actuator you are referring too, not the wastegate itself.

the wastegate is the flap in the rear of the turbo that vents the excess gasses.

how did they come to the conclusion that the wastegate was siezed? i'd imagine you'd need to rip the dump pipe off to be 100% sure, in which case you would fix it there and then.

Nar, too late

Once you remove the Turbo heat shield, you can get to the actuator/rod. From there you should be able to move it by hand (it will be stiff, but you should get a pretty good idea if it's seized or not.)

i'll try have a look at it this week some time, but have to take it back to the place i got it from so they can fix my p/steering noise properly anyway. they can sort out the turbo at the same time
