Nissan Frontier Removal upper/lower plenum,injectors,valve covers,fuel rail,knock sensor part 1of3

2000 Nissan Frontier V6 3.3L
part 1of 3 This is a step by step ( long video- get your popcorn and take notes) I take off the intake manifold upper plenum, fuel rail, fuel injectors, remove and replace valve cover gaskets (clean the valve covers and paint them), remove lower intake, replace knock sensor
*** I used RTV on the lower intake, but i suggest not to do that. i did, because i have a pitted surface. hopefully it holds up. but i realized that some fuel does get burned and some fuel does get sprayed in that intake area...so do not use RTV there like i did !!!
Here is a list of parts that i used
