okay ive tried it all. im using a pfab log with a gt3076 and the 4 bolts that hold the turbo to the manifold always back out. it never fails. recently i took the whole manifold off and had them retapped using bigger stage 8 bolts. i just checked them today and one has already backed out completely. its not even there anymore. how dumb would it be to use locktite? i dont get why this keeps happening. i wish i could just bolt them in and not ever worry about them again. someone please help. im thinking of using locktite but im not sure if id ever be able to get them off later down the road. thanks for any help.

I used nord-loc washers and a nut. You may need longer bolts to do so tho. This is on a pfab elt not sure how much room u have with the log. Also used nord-loc washers on the manifold to block.

I use Stage 8 bolts for turbo to manifold.

I use NordLocks for the turbine housing - CHRA - compressor cover.

I'm doing the same as this man. I've stopped having issues ever since.

You could safety wire them where you drill holes through the head of the bolt and use safety wire to prevent them from spinning.

Common practice in motorcycle racing, check out this guide:

For example, check out this wastegate on an Indycar. In this case, the safety wire goes through the studs preventing the nuts from coming off:

Another vote for nordlock washers. I'm using longer arp studs also.

thanks for all the input guys. i have already tried arp studs that have backed out. this time i will use the nord loc washers and i will pray that they stay in this time. anybody have a link to the arp studs they used? i want to compare and see if i am using the same ones. thanks.
