Turbo oil line bolts keeps breaking

[90etalontsi]

I am currently putting a used engine w/new head in my Tsi. While bolting the oil return line up i have broke 2 bolts. I have had the bolts pulled out by the local speed shop. I am wondering why they keep breaking.

to much torque, wrong type of fastener could be a number of things check to make sure you are not using long bolts and you are using the correct size and everything. and check your torque specs

try using anti sieze

Mine broke also,perhaps from being 18 years old.
