Rodent chewed through both ends of a twin lead wire which passes above the passenger side valve cover then underneath the intake manifold. I cannot find the loose end under the manifold. I hope I don't have to pull the manifold to fix. Suggestions, please. Mark in NJ

check for a rodent nest in the hvc system, they usually get in from the air intake for the hvac system which should be located on the passenger side under the cowl cover. if you have a cabin air filter they love to chew those up and make a nest in it.

the best first thing to do is check for a rodent nest in your system, look into the hvac air intake which should be under the cowl cover on the passenger side. if there is debris in there you have a rodent nest which needs cleared out. if your vehicle has a cabin air filter this is where the intake for the hvac is.

Locate the powersteering pump on the top of the passenger side of the engine. If you look in between the pump and the intake manifold you will see the cam sensor. The connector for the sensor is on the front of the engine right above the valve cover on the passenger side. It is has three wires.

PCV LOCATED AT THE DRIVE BELT END OF THE ENGINE UNDER THE INTAKE MANIFOLD AND ATTACHED TO THE BREATHER SEPERATOR.YOU HAVE TO REMOVE PCV FROM UNDERNEATH CAR HARD TO REMOVE PCV FROM TOP OF THE ENGINE.

on the passeger side of the intake plenum there will be a sensor called the MAF sensor. It will have three wires going to it. The PCV valve is under the cover that the MAF sensor mounts to.

Have to pull the plastic engine cover,on the pass. side of the engine at the end of the plastic intake
manifold there is a cover with a plastic "nut" on the top,1/4 turn and the valve is underneath,be careful to get the o-rings in right ,(2 I think) some have a small spring on top to keep the valve seated

The PCV valve is located under the map sensor in a plastic housing. If you stand on the passenger side of the vehicle and look under the hood, the map sensor is the sensor right in front of you.

It should have three wires going to it. If you look closely, the sensor is clipped into a type of cap. If you grab the cap the sensor is clipped into and twist it counterclockwise, it should come off and the pcv valve will be inside. You may need new orings to prevent oil consumption. You may also need a needlenose pliers to remove the sensor from the upper intake manifold.

Hope help.

There are several areas of possible leakage. One is the hose and plastic outlet from the intake manifold on the passenger side of the engine. The hose runs low, underneath the alternator. The plastic outlet cracks, the hose gets old, the clamps on the hose can also be loose. The replacement outlet from the dealer is steel, not plastic.
Another possibility for leakage is on the driver's side of the intake manifold. Underneath the air inlet is a metal cover on the end of the intake manifold. This covers the coolant passages at the end of the intake. Mine was oozing antifreeze..you don't have to pull the intake to replace this.
The other place for leaks is the intake itself..requiring removal of the intake. I've done this...I don't think it is that bad of a job. However, if you put in a new intake, don't forget to put in a pcv valve..it fits under a small cover at the right rear of the intake manifold.

The starter motor on the Northstar engines is underneath the intake manifold,it sits in the valley just above the crank shaft.

Its in the upper intake manifold on passanger side. Inside the manifold. Be sure to put o-ring on pcv or check engine light will come on.
