Known Problems

3.0L engines may develop an excessive oil consumption issue. Blue oil smoke may be noted from the exhaust during deceleration conditions (high engine vacuum). Our technicians tell us that this condition can be caused by valve guides dropping out of position. Updated valve guides with a revised snap ring grove are available to correct this issue.

Engine oil leaks may develop from the following areas: Valve cover gaskets, cam plugs at rear of the cylinder head, cam seals, front crankshaft seal, and the oil filter bracket. Leaking seals and gaskets should be replaced. Due to mis-machining of the mating surfaces, as special gasket is required to correct the oil filter bracket leak.

On 2.4L 4 cylinder engines a whining noise may be noted when the engine is cold and the rpm is in the 1800-2000 range. Our technicians tell us that most commonly this type of noise is coming from the engine oil pump. The repair is to replace the front case assembly and both the drive and driven oil pump gears.

Carbon buildup on the top of the piston is common and increases with mileage and over time. Symptoms can vary from light ticking to hammering/knocking noises. Performing a Fuel injector cleaning service will often also remove enough carbon build up to lessen any noise concerns related this issue.

A rough idle or driveway stalling condition may occur with fault code 15 stored in the engine control module (ECM). Our technicians tell us that if the engine and ECM grounds test OK, and the throttle and idle speed control motor position sensors are functioning correctly, then adding an additional ground lead may be necessary to correct this issue.

Some engines may develop driveability concerns due to carbon built up on the intake valves. Our technicians tell us that performing a fuel injector cleaning procedure can also help to remove intake valve deposits. Extremely heavy deposits may require cylinder head removal so that the valves can be removed and cleaned with a wire brush.

The engine may develop a hesitation on acceleration. Our technicians tell us that the EGR valve back pressure tube may become plugged. In most cases cleaning the tube will correct the concern, EGR valve replacement is generally not required to correct this issue.

A low idle or stalling condition may be the result of a dirty throttle body. Our technicians recommend cleaning the throttle body at regular intervals (15k miles) to avoid this condition.

An exhaust leak and/or chirp type noise may develop from the exhaust manifold to header pipe connection. Our technicians tell us that replacing the exhaust seal ring and flange springs, along with sizing the header pipe flange will generally correct this concern.

Hard starting, long crank times, and rough idle may be noted, especially after the vehicle has been parked for a period of time. Leaking fuel injectors are a common cause for this concern.

A pinging or snapping noise may be heard from under the middle of the vehicle after the engine is turned off. Our technicians tell us that the noise may be coming from the exhaust. If that is the case the exhaust pipe extension and resonator assembly should be replaced.

A tappet/lash adjuster noise may be noted from the 3.0L engines. Our technicians tell us that proper testing of the lash adjusters  should be performed before replacing any parts. A full crankcase of clean engine oil is necessary before attempting to determine if any lash adjusters are bleeding down and causing a noise concern.
