okay so i attempted to change my oil pressure sensor, which i removed the distributor and wires today looked around and couldnt find ****, or maybe it was harder to find but i searched and tryd to feel for any plug/sensor... so as i gave up trying, i looked at some of my hoses and from the front of the engine next to where the compressor would be is a valve to a hose, then the hose go along top to the side of the driver side on the engine to the manifold in the back, now the hose looks eaten up and demolited at the end, and the valves that go to the hose looks old and rusted, which i think the valve up top are the air pump check valves? but the valve going into the manifold block on the side of the engine with the hose going into it, i dunno tomuch about heres some pics.. thanks for any 2 cents id like to change it all myself

 

heres the pics

 

EGR hose??

 

Yep, thats one of them stupid egr hoses.

 

is there any certain way to change this, im buying the new hose tomm, and im replacing this, but i gotta know a way to get this one off the front of the engine, and off the manifold line, underneath the hose connections look like open wrench fittings, does a new valve need to be replaced?

but does the hose just pull off and out?

 

what year? if you're lucky you could just blank it off and have the truck run better...

 

so im taking it to the shop to get put on friday because i cant get it off wit any luck... i also looked around and in front ontop of the engine coming off the passenger side, i noticed another line that is cracked im also curious bout this one as i rather order the parts and bring it in to just have them put it in, ill have to take photos brb
