Intakes removed and new gaskets purchased [also removed valve covers since they were easy to get to even though they were not leaking] ..... I see alot of past chatter about using Hylomar on the new Intake gaskets AND the new valve cover gaskets,, does that apply to the earlier models only ??? A BMW tech said to reassemble both and not to use anything on either of the new gaskets- intakes or valve covers !!!
