Hey everyone

My nuts that hold my turbo to my manifold keep loosing up on the studs. is there anyway to stop this?

damage from the first time:

I found it happening faster the second time:

Also, I've tightened the nuts up again, but I can still feel exhaust coming out the side, do you think something is warped? There is a gasket between the turbo and the manifold.

I run stainless steel cone type lock nuts. So far so good.

I have some from before that I was running while waiting for the new studs, and nuts to come in. I may switch back to them.

i only have 200 miles on it, but im running stainless studs, lock washers, nuts and red loctite and am fine so far. if i have trouble, ill the the same but with these http://www.zorotools.com/g/00056511/k-G1888372?utm_source=google_shopping&utm_medium=cpc&utm_campaign=Google_Shopping_Feed&kw={keyword}&gclid=CIX9zqb5kbECFeEDQAodUHh-dQ which is waht i believe spindoctor is talking about. the thread on them is actually deformed, so they go on pretty hard. i cant really run bolts because there isnt enough room to squeeze it in there

Run to the auto parts store and grab some exhaust repair putty. Dab a little on the nuts/studs and they wont come off until you break them loose. ~$5

You need new nuts. OEM ones are fine, they're locking nuts, and tend to back off after being undone and replaced a couple of times. Replace with new, and they'll stay on untill you physically unbolt them yourself.

this may sound crazy but....check your afr and egt...I was having this problem on my old turbo setup which was running lean all the time....now the lean issue fixed, no more bolts backing out

Did you replace the gasket after the nuts backed off? When the flange gets loose the gasket is basically going to melt, so it needs to be replaced before you tighten everything down again. This is the big down side to running a gasket.

May sound stupid but: What options are there if you dont run a gasket in this location??

I hear time and time again to only run ARP bolts/nuts, I checked on prices and only ~$10 for a set of four.

You just bolt it together, just have to make sure the 2 surfaces are perfectly flat. That gasket is only there to seal if the surfaces are not perfectly flat.
