"blew out" is a bit dramatic...If it's a pcv hose it should have a ton of suction at the open end or where it had been attached.Also with that hose detached, your engine won't run at idle very well or at all. Most often, any hose that becomes disconnected stays pretty close to where it's supposed to be attached. Simply look for a clean attachment nipple near where you found the hose and put it back there.

The egr valve should be located in the front of the intake manifold by the thermostat housing and alternator. It should be an electronic egr with one electrical connector.

Were is the air intake sensor locate


Hi!
It is the part where the air duct coming from the air filter housing connects to, right between the air duct and the flex hose that connects it to the intake manifold.
THIS IS A MAF SENSOR ADAPTER. THE SENSOR WOULD BE MOUNTED ON THE RECTANGULAR BASE AND FASTENED WITH THE TWO SCREWS

THIS IS THE IAC SENSOR, MOUNTED ON THE INTAKE MANIFOLD, BY THE MAF SENSOR.
A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

Purge solenoid location


which vehicle are you actually looking for the purge solenoid on? you have 2 vehicles listed in your question. i'll answer both, lol

the locations are described as if you are looking at the engine from the front of the car with hood open.

on the blazer:

it is located on the left side of the intake manifold just under and behind the throttlebody. it is a canister looking device.

on the silverado:

it is located on the intake manifold on the left side in about the same spot as the blazer. providing the silverado has the 5.3 or 5.7 liter engine. if it also has the 4.3 then obviously it will be the same.

hope this helps!
