Question about 2004 Dodge Ram 1500

2004 Dodg Ram 1500 5.7 L Hemi

My engine light has been going on and off for several months now. I feel a loss of power at times and a ticking from the right side of the engine. When I took off the air intake and looked at the butterfly it was crusted BLACK on the inside. And damn I mean like 1mm thick black. So I cleaned all that out and began to use "Tune Up in a Can" and Seafoam like products. (The tail pipes were also emitting a black substance with liquid) Several cans of this, and the engine light would come off. I had also previously noticed that there was a white fog coming from the oil cap after the engine was hot. I was told that this was normal. The same with a orange like substance being deposited on the oil cap (personally I thought that was ****) and after using the canned tune ups both the "fog" and the condensation within the oil cap were gone. Nice and dry. At that time I also notice Hemi was performing like she was brand new. Now the ticking sound is louder than ever and when driving at 60km with cruise on or off the engine will rpm-bounce. And then you can feel it rocking slightly. Higher speeds, not a problem. I went to Mr. Lube to get my PCV valve replaced and they said they couldn't find it, and it "Must be internal". Where is the bugger? Is it that screw cap on the right side of the intake manifold? And if so it really didn't seem to want to come out, and to be honest I wasn't going to force it very hard without knowing exactly what I was doing. Thanks in advance. Matthias

    I haven't had the code scanned yet. Everyone wants labor to do it. I was just going to buy a Tuner/Diag or even buy one from a store, use it and then return it citing that it didn't work. But I'd rather not be dishonest about it.

    Ok so here's what's going on now. I got some Seafoam lube to spray into the PVC valve. That thing was gunked up horribly. I mean like two shop cloths gunked up. I cleaned it out with the seafoam and gently wiped away any dirt.

    2nd problem, still ticking badly and when I opened the oil cap the condensation is back. The engine light went off after cleaning the pvc valve.

I have a 2005 Dodge Ram 1500 5.7ltr Hemi....I had a significant issue with loss of oil...the bottom of this engine and vehicle is as dry as they come. No smoke from the tail pipe...however the inside is dark...not that light grey clean burning look...I'm also seeing oil residue inside the air breather....I searched all over that engine to find what knew a PCV should look like...I finally broke down, drove to the local Dodge service dept. and asked one of their mechanics to come show me...facing the engine...on the passenger side of the engine, behind the throttle body cover is what looks like a plug with a raised center clip you grab and twist clockwise to unlock and counter to took a bit of prying with a small flathead screwdrive, but it popped up. The check valve in it was sluggish (due to the oil) and probably not functioning to full capacity. The dealership charges about $42 per but cut me a "deal" and charged me $34. You do have to remove the throttle body cover to see it and ultimately remove it....2 screws and you're there.

04 DODGE Ram hemi cylinder 3 misfire

Check engine compression and compare. then test running engine compression most engines have about 130-170 cranking compression and about 90-110 running compression. OR bring that cylinder to its Top Dead Center compression stroke apply air to the cylinder and check to see where the air is going open throttle plate bad intake valve, from exhaust pipe bad exhaust valve, from oil cap piston rings.

There is no standard interval for the CE/MIL light. You need to get the codes scanned at a local AP store to see what codes you have.

I have an 03 Ram 1500, engine light is on, I had

p0440 - Evap. system performance (this could be something as simple as not turning the gas cap several times after you fill up.

p0456 - Evap leak monitor Small leak detected. - Could be related to the previous code.

p2106 - Throttle Actuator Control System - Forced limited power : This one you might have noticed the vehicle running rough, overdrive not working properly and cruise control will not set.

p2175 - Throttle Actuator Control System - Low airflow detected.

What you might want to try first is have the codes cleared which most auto parts stores offer this for nothing (unless you have a programmer then you can do it yourself). Pour in some fuel injector cleaner into your gas, put a new air filter on. And when you fill up your gas tank, crank the cap several times when you put it back on.
See if the codes come back on after that.

Slide a large piece of cardboard under the truck after driving for ten minutes note in which area directly above the spot on the cardboard the oil is coming from then get under the vehicle with a drop light to look for the origin of the leak, if no leak is detected then it may be the engine is burning oil this could either be valve stem seals or broke or worn oil rings.
