Pull valve cover off and look for any bad lifters. Or could be piston rod. Sounds like sticky lifter. Not good.

Ticking in the engine along with service light-p0442


Your engine code (DTC P0442 Evaporative Emission (EVAP) System Small Leak Detected ) should not have anything to do with a ticking sound. The evaporative system keeps you from having a gas smell under the hood and in the car.

As far as ticking goes ... it could be many things. You are correct, it could be lifters. If you take a long screwdriver and with the engine running place the handle end against your ear and touch the blade end to the top of the valve cover the screwdriver will act as a stethescope. If the ticking gets a lot louder somewhere on the valve cover then yes, you have a lifter making noise. If the motor ran really low on oil, and then one or more lifters started ticking you can try running about a half quart of transmission fluid in the oil for about 15 minutes at ididle while gently changing the rpms between idle and about 2500 to see if it loosens up the lifter(s). Change the oil after you do this.

To test the PCV valve, with the engine running pull the PCV valve out of the valve cover (leave it attached to the vaccuum hose) and place the tip of your finger against the now exposed tip of the PCV valve. It should make a snapping noise and **** your finger against the opening in the valve. If it does not, then make sure the vaccuum hose does not have a leak in it. If the hose is good, shut the car off, remove the valve from the vaccuum hose, and use some carburetor spray and clean it out. I clean mine each time I change the spark plugs. If the valve is stuck or clogged this could be causing the oil pooiing problem in the air intake tube you describe from excessive crankcase pressure.

If you still have not found the ticking noise, it could also be in the lower end of the motor. This is the only "bad" place for it to be out of what I have described. If it is a lifter and the noise is not really loud, it is not dangerous to drive.

How do you no if your lifters are going bad


Bad lifters will make a loud "ticking" sound. This noise can be isolated from other engine noises by putting a section of rubber hose (like a heater hose) up to your ear and using it like a stethescope. Lifter noise will be coming from the valve cover area.

2004 Dodge Dakota 3.7L V6, manual. Below


I suspect you have hydraulic lifters and the sludgy oil could plug up your lifters - as well as running that low on oil. Top off your oil and get an oil additive engine cleaner, warm your engine at idle only then change oil when warm. Add 1 quart of marvel mystery oil to the crankcase then top off with high mileage oil, like Valvoline. Run motor at idle only and see if this cures the problem - if not then you may need to remove the intake and replace your lifters, a costly and time consuming job. I would not try driving as you may waste the cylinder head or block by running a stuck lifter. There is also an oil additive specifically for stuck lifter and I think I would add that as well as the Marvel.
I hope the quick fix works for you and good luck!!!

2004 Dodge Dakota 3.7L V6, manual. Below freezing out. Started up my truck it started making lifter noises upon start-up. I thought it was cold, so I let it idle for 10-15 minutes. As it was idling,...


P0300 Random/Multiple Cylinder Misfire Detected

P0304 Cylinder 4 Misfire Detected

If a cylinder is not firing it could make that noise. Check/replace your plug wires use dielectric grease in the boot connections. Could be a bad plug as well but I would guess a bad plug wire...

Isuzu 3.2 L V6 Engine clacking


The problem with the 3.2 ticking noise is the worn rocker rod on the intake side. These rods support the rockers and the slave rockers for the exhaust. The slave rockers wear a groove in the rocker shafts that create extra clearance. The extra clearance is too much for the lifters to cover and then you get the tapping noise. The only cure is to replace the intake rocker shafts. When you get into the valve train, it is obvious what the problem is.
