Your description sounds a lot like a PCV (Positive Crankcase Ventilation) installation.

These draw fumes that originate inside of the engine from hot oil and piston blowby and send them through the intake system to be consumed along with the fuel charge.
Those fumes were once vented into open air but most agree those were not all that good to breath so they are now polished off by running them through the engine and catalytic convertor.

1998 explorer 4wd xlt 6 cyl. single overhead cam. I cant find the emissions purge valve solenoid.


Look for a plastic cylindrical object about 2 inches high, mounted on the firewall near the right fender. This is the purge valve. You should see a thick black hose entering it from the driver's side of the unit.

Where is connection


    • Locate the accumulator bolted to the firewall on your automobile. It usually bolts to the passenger side firewall but this is not a rule. However, it will be located on the passenger side of the engine bay. The accumulator is approximately 12-inches in length, 4-inches in diameter and has at least tow large hoses extending from it. These hoses are the high side and low side hoses. Locate the metal portions of the high side and low side hoses. Each hose comprises of a hard-metal line and soft-rubber line secured together. The metal portion of the hose bolts to the accumulator. Locate the low side and high side valves. They are located on the metal portion of the hose connected to the accumulator and both have black plastic caps covering them. The high side valve is a 16mm quick disconnect valve and the low side valve is a 13mm quick disconnect valve

Replace heater core


    A heater core transfers heat from a 1994 Ford Ranger's engine to the passenger compartment by running hot radiator coolant through a serpentine of tubing. Air blows past the hot fins of the heater core and into the truck cab.

    The hoses running to and from the heater core must be removed from the engine compartment, but the core itself is accessed from inside the passenger compartment, on the driver's side next to the center console.

    1. Turn off the engine, open the hood and remove the battery cable from the negative terminal. Make sure the engine is cool.

    2. Attach a 3/8-inch interior diameter hose to the drain outlet on the bottom rear corner of the radiator on the driver's side, and place the bottom end in a resealable plastic container. Turn the drain valve (located above the drain outlet) counterclockwise with a pair of pliers. Drain the engine coolant into the resealable container, then close the valve by turning it clockwise. Remove the hose from the outlet.

    3. Loosen the hose clamps on the radiator hoses where they attach to the heater core on the firewall. Remove the hoses.

    4. Unscrew the screws holding the underdash cover in place on the driver's side of the passenger compartment. Remove the underdash cover.

    5. Unscrew the four screws on the cylindrical heater core access cover and remove it. Remove the heater core by pulling it down and toward the rear of the vehicle. Replace the unit with a new heater core.

    6. Reinstall the heater core access cover and screw in the retaining screws. Replace the underdash cover and screw it into place.

    7. Replace the radiator hoses on the heater core in the engine compartment. Tighten the hose clamps. Add coolant until the level is between the minimum and maximum marks on the reservoir.

    8. Replace the battery cable and start the engine. Check the system for leaks.

Were is the starter motor in a nissan pulsarq 1988 hatch


On most Nissans, the starter-motor is located on the right side of the engine when your standing looking into the engine bay from the front of the car, it should be a fairly large cylindrically shaped object, 5-6 inches in diameter, about the same color as the engine block, and has a smaller (2 inch approx) cylindric object attached to it, this is the solenoid, which engages the motor.

If you are sure this is the problem, removal is quite easy, usually 2-4 hex bolts holding it in place, to test it, connect the car's own battery to the terminals on the solenoid and motor, and if it doesn't turn, it's shot. Repair is fairly inexpensive, but replacement might be. Good luck!

Where is the egr valve on a 307


They can be located in a number of places. one way to locate is look for a corrigated metal pipe, it is about an inch in diameter and will come from the exhaust manifold area and travel up to the inlet manifold. The valve is usually the cylindrical object on the inlet manifold where the pipe meets.
It will have a wiring plug going into it.
