I am not 100% sure, but, may have a small black foam filter about 2cm square in the main air filter housing with a pipe leading down to the face of the engine block (front of engine under manifold). There you should find a small black box bolted to the block, this will receive the hose from the air filter housing. Inside this there will be a valve.This assembly is called the oil separator. All these parts make the PCV valve system (positive crankase ventilation)
To test - clean foam filter with methylated spirits. Remove oil separator and small valve. Valve should rattle when shaken. Flush out valve and separator with Carb cleaner. Check gasket, renew if necessary. Replace in reversal of removal.
It would do no harm to clean your EGR pipe and valve with carb cleaner whilst doing this.
N.B the PCV valve is under the exhaust manifold and access id HARD. So you may want to remove the manifold first.
Buy a haynes manual aswell this will help if you have the older Pulse Air system and not the EGR valve as associated pipe work makes getting to the PCV valve difficult. Hope this help. Not a difficult job, just take care and time.
The thermostat on a 2001 Ford Escort is located near the thermostat housing. It is also near the cylinder head.
The heater valve is located inside the heater box.
The camshaft position sensor on a 2001 Ford Escort is located on the passenger side of the motor. It is right on top of the motor to the left of the valve cover.
It connects to the crankcase vent, the air filter and the valve cover.
under the intake am sure
Changed the pcv valve. It fixed my p171 code on my 2001 escort. Have to get the PVC valve from the ford place. They are the only one that carry the right one. PCV valve is available at AutoZone part # PCV 1001 for 2001 Escort SOHC 2.0L
The 1993 Ford escort did not come with an EGR valve. It is one of a few year models that do not have one.
It is located under the intake manifold between the engine and the firewall.
Yes , the 2001 Ford Escort is front wheel drive
( 12.8 U.S. gallons ) in the 2001 Ford Escort models
The PCV valve is in the crankcase vent tube It is on the right of the exhaust heat shield below the ignition wires going into the coil.
The PCV valve on a 1996 Ford Escort 1.9L is located between the engine and the radiator. It is near the vacuum hose.
