Generation IV External Engine - TRAP DOOR IN MY FRONT ENGINE COVOR!!!!! wtf what is it

Ok I have a 418 texas speed engine, the front engine cover has a little trap door looking thing where the cam would be that looks like you could pop it off with a flat head screwdriver.

is this a trap door for replacing the cam without pulling the crank pully and covor? or does this serve as some other kind of purpose and should I leave it alone?

I will try to get a picture of it tomorrow

Sounds like it. Pics will help. Post them up asap:nod:

I will try, yeah ive never seen a covor with a door looking thingy I have seen ones that are 2 piece so you can swap cams without pulling crank I really would like to know what it is before I go popping it off

ok well I googled it and looks to be just a regular ls2 front cover, I dont know what its for but I doubt its for removing the cam I think I will leave it alone and just pull the crank pully

probably a cam sensor plug or something if the cam sensor isnt in the cover.

Its an early LS2 timing chain cover. The later ones where solid. Also its not a door. Its a metal plate with some rubber backing on it. We believe GM used this style for sound suppression or has something to do with the cam sensor in the cover.

Like this?
