can i just make my own gaskets using gasket making material and rtv for the lower intake manifold to heads? if so do i need to double them up (make four gaskets 2 for each side)? or is doing this asking for trouble.
for the record, i wouldn't do it to the lower intake but i have done it to the upper to lower with no problems, i was pulling the thing off alot (turbo build, etc.) i got tired of buying a new on lol
