Turbo bolts coming loose

[gr33n]

please help me.... I have no idea why this is happening to me, but the 4 bolts that connect the turbo to the manifolds are always coming loose..... I have tightening shins under them (I replace them every other week or so) but despite of that it comes loose in about 2-3 days!!!

please, has anyone had this problem or?

The best thing to do is tighten them when the manifold is hot since they will shrink down as they cool. If you tighten them when it's cool, they'll expand and loosen up again as the manifold heats up. I had a problem like this on one of my studs and tightening it when hot took care of it. make sure you drive it around for a while to warm it properly and then have at it.

Let me know if that helps,

Andy

You can also use slightly longer bolts, with a nut on the end of each. Tighten the bolts down, then tighten a nut on each end. I dont suggest doing this while hot, as its a tight space and you will probably burn something.

Good luck.

I don't suggest using any other turbo bolt besides OEM. Even ARP bolts are known to break. Tightening it down like Andy suggested with some quality grade lock washers should do the trick

WTF

I didn't say go to homedepot and get 4 snapper bolts. Very sorry if I was not more specific.

"You can also try getting 4 longer stainless bolts from SFO, with stainless nuts."

Doing what Andy said should work yes, but if it doesn't I was giving him another option.

What kind of washers are you using? Get some star washers.

"New" OEM turbo washers-

I use oem bolts and washers. I use 2 washers for each bolt. The washers have a convex/concave side. I put the convex sides towards each other which leaves the concave toward the bolt head and manifold. I put a dab of copper antiseize on each and torque to 45ft lbs (Recommended 40-47ft lbs) I'll check them once or twice after. I've never had any issues with them backing out.
