Waste Gate problem :(

[Ski]

One of the waste gate nuts twised off / snapped off on me while i was tightening it..

question 1 :

can I run with 1 less bolt ? (i think theres 4 or 5 lleft)

question 2 :

Is it part of the lower wastegate (i.e. will i need a new wastegatee ?) or are the bolts seperate ?

You may be ok if the cap doesn't leak boost. Unfortunately, the wastegate is only available as a complete unit and that's megabux. I'd strip it down and try to replace the broken stud.

Any suggestions how i can replace the broken stud? An engineering company?

chop old one off, drill the hole have it re tapped and a new threaded bar put in.

Did it break right down the bottom? ie is there anything left to get hold of if you take the cap off again?

[Ski]

Yes theres lots left.. it twisted off right at the nut. I didnt even put much pressure on it..

it seems to be holding fine (no leaks)

Exactly the same happened to me. I had luck I could get hold on a old wastegate complete with cap, cooling etc for 10 euro. I took two studs out and replaced them. Maybe I have some studs left.

[Ski]

so you can replace the studs?

Erikb if you have a stud free I would do backflips to get one!

Have seen some wastegates going on the Bay of E lately, not sure if there are still any on there tho... worth a look tho

[Erikb]

Ski,

I have to check, but I think I will have some left.

I will let you know as soon as possible.

I did drive 2000 km with one stud less, it wasnt loosing pressure. But mine isnt tuned.

kind regards,

Erik

Thanx Erik, much appreciated

[Erikb]

ok, ski I have three pieces left. I will try to get them loose and send you one. Please send me your address with a PM.

[Ski]

Erik you are a star!!! I will kiss your feet if I ever meet you!

OK now softly softly, dont just try to undo the stud with mole grips, you want to soak that baby in Plus Gas for a while first, then go easy, if it doesn't just twist out you could try a LITTLE heat from a butane torch, dont melt the alloy.. remember to hook the diaphragm out of the way of the flame!! If it doesn't come leave it to soak a bit more.

thanx for the wise words, I will follow this method like a bible!
