at first i had the ve tb on and i did locktite the screws, well when my friend got his 16ve from miko the tb was damaged, at this point i had already put the de tb on my car so i had the 20ve one layin around.. i tried to loosen the screws to relocktite them an it wasn't happening.. they wouldn't budge at all.. so i put it on his car an its been fine for almost 2 years. prolly should check them soon.
