Question about 2000 Dodge Ram Maxi

1 Answer

Using oil 2002 Dodge 5.9 I'm told that it may be due to the intake gasket sucking in and pulling oil into the carb. also causing fuel to run lean and damaging cataletic comverter. Any truth to this.

    I have already replaced the intake gasket (1996 ram 1500 5.9)once at 60,000K or so & now at 109,000 it needs replaced again. I did have to repace the cat. converter (under a recall ) but did not relate that to the intake gasket.It does consume about 2 1/2 quarts of oil every 3,000 miles. I don't know if ther is a better gasket out ther & if so where to get it or how to find about it !

    Any smoking from tailpipe on start ups or letting off, sitting idling? Has a compression test, (wet & dry) ever been done? Has anyone knowledgable taken a close look at spark plugs for signs?

If smoking rings bad .if not look for external leak .oil pan gasket .rear main seal. front timing cover seal.look make sure oil return holes not stop up.look or replace valve seal and guide.

Hello , I have a 2000 dodge Durango v6 with a po305 code , I replaced basic plugs wires cap & rotor . It smells rich with fuel and has a little mis at idle . Any ideas as to why it would be running...

P0305 code is a cylinder #5 missfire. The codes last digit is the effected cylinder, i.e. P0305 is cylinder #5 and a P0302 is cylinder #2 and so on. A P0300 is a multi-cylinder missfire.
Thoery 1: Ignition system! If the cylinder is being injected with fuel and not getting spark, the un-burned fuel would simply be pumped out the exhaust system and can be the source of the fuel smell. Check the ignition system and the firing order. I know you said you already did this, but I have to include this for other people in the future who might be using this to help them with a simillar problem.
Theory 2: Bad injector! If #5 cylinder injector is stuck at full fuel (leaking badly due to an internal mechanical failure) it will be pumping way too much fuel into the cylinder for the cylinder to burn. The outcome is the same as before, it just pumps the raw fuel out the exhaust system. Just as before, compare 2 cylinders by inspecting the spark plugs of #3 and #5. If an injector is stuck, that cylinder spark plug will be soaked with fuel. Injectors cannot be repaired, just replaced.
Theory 3: Low compression! If #5 cylinder is low on compression it will not fire the fuel as it is injected. A simple compression test is needed to tell if there is a mechanical failure internal to the engine causing low compression.
Theory 4: Bad intake plenum gasket! The intake manifold has a steel plate bolted onto the bottom of it with a gasket called a plenum. This plate is inside the lifter valley. If this gasket fails it will cause a vaccume leak into the intake manifold that will create a lean mixture condition for the cylinder that is nearest the failed spot. This lean mixture does not light or burn effectivly and can cause an unburned mixture to enter exhaust manifold causing the same sympoms as above.
Obviously this problem needs further diagnostics to pin-point the source of the failure. These are simply starting points and there can be many other things that can cause this type of problem, but these are the most likely. Hope this can be of some help, have more questions? Just ask!

Getting a too lean on bank one service engine code. We have replaced spark plugs, wires. one of the coils. The car has 109,000 miles and has been using a little oil. I have to put about 1 quart after...

Lean codes are caused by the engine running lean. What this means is that there is too much air and not enough fuel. There are several things that can cause this. The most likely causes would be a clogged-up fuel filter, a weak fuel pump, a broken or leaking vacuum hose, a leaking vacuum brake booster, a torn air intake "snorkel" that is torn between the Mass Airflow Sensor (MAF) and the Throttle Body, or a bad MAF Sensor. An intake manifold leak can also cause this but it is pretty rare on your car.
With the mileage on your vehicle, I would replace the fuel filter just because it probably needs it anyway. (They are supposed to be changed every 30,000 miles) Then, if you don't find anything wrong with the vacuum hoses or the intake snorkel, I would say that the most probable cause would be a defective MAF Sensor.

My dodge is a 1996 dodge ram 1500 with a 3.9 v6. my truck runs rough most of the time, i took it to autozone and they said that the check engine light was indicating that the truck was running too lean....

intermittent lean condition may be caused by leaking intake manifold gaskets. Get some carb cleaner and start the truck. Open the hood and spray carb cleaner on the intake manifold gaskets. If the engine reacts at all, you have a gasket leak. If you have questions, please let me know.

What is system too lean bank1 and bank2

The air/fuel mixture has too much air or not enough gas. Usually the former, as the PCM uses airflow sensing to calculate the proper amount of fuel to inject. The common causes of this condition is a vacuum leak. Vacuum leaks may be in the hoses connected to the intake manifold or in the manifold gaskets. Check all hoses for brittleness, leaks, and proper fit/tightness to their connections. Test the intake gaskets for leaks by spraying carb cleaner or ether at the gaskets with the engine running. If the engine speeds when you spray, the gaskets are leaking and must be replaced. If you have more questions, please let us know.

I have 2 codes on my 2000 silverado they are 171 and 174 what do i have to do to repair my code checker says it is right and left bank running lean

Lots of things can cause an engine to run lean. The most common problem with the 3rd gen small block is the upper plenume (the intake manifold) gaskets **** air. This is an easy job, some of the bolts look hard to get to but they really are not.
Make sure you have good fuel pressure and there are not any other codes in the system.
The best way to see if the intake gaskets are sucking air would be to spray a small amout of carb spray around the intake while the engine is running and see if it starts running real bad, like a missfire. BUT becarful with this as carb spray is flamable and an engine can be hot, so you would want to try this after the engine has cooled down.

I do know these are good for sucking in the gasket for the pan on the bottom of the intake and causing spark knock and oil consumption but not a throttle body gasket.
