The check engine light came on this morning but not when it first started happening. Plan to take it up to auto zone and see if they can get a code from it but my programmer has a dignostic on it and is not saying it has an issue but will not shut of the light. Due to the check engine light I am in reduced power now. Changed the spark plugs 20000 miles ago and just cleaned air filter and change oil less than 1500 miles ago. Also noticed this morning lights dimming out at idle

Well the only code that poped up was the ac sensor but I knew that that was broke dodge just wants an arm and leg for a new one. I did take a timing light and find out that one of the wires coming of the coild pack was not producing spark so I ordered a new power pack. We will see how well that works. However I have alot of blow back of oil going in to my air filter and up in to the air intake. Is this the power pack causing that or do I need to take it to dodge to have the rings checked?

A dead cylender will not burn gas. As a result, it could be thining out the oil. At that mileage, it shouldn't have any blow by unless the oil wasn't ever changed. It isn't good running it like that. As far as the coil, before paying for a new one, make sure there is power to it.

Let me know what you find.

When I take the wire off the coil pack there is arc to the closest bolt off the coil pack. But when I hook the timing light to it there is no flash so it is either the pack which I broke yesterday taking it off so needs to be replaced now or the wire. But that wire runs to the 3 cylinder on the passenger side and it has a flash over there so I am going out on the limb and hoping that it is just the coil pack. Not that I have a choice after I broke it. I am the oil I run royal purple all the way up to the last oil change 1500 miles ago I put valvoline high mileage in it because I knew I was going to florida and that is 1400 miles round trip but on the next oil change it will get royal purple again. The cylinder is not all the way dead because of the other spark plug is giving spark but I am hoping that this coil pack takes care of it all. When they get the coil pack in I will post and let you know THANKS FOR THE HELP. Two minds are greater than one towards trouble shooting

Let me know. I'm interested in hearing what you find. If you still have a miss in that cylender, check it for compression.

Put the new coil pack in and still have nothing on that wire so took it to dodge and have them check the pcm if it is that it is covered with the warrenty. If it is not we will find out what it is I guess

Ok so it went to dodge dealership and after a 100$ bill on the day they replaced 2 spark plugs that some how something got in the #6 cylinder and closed both the plugs so that explains why I had a dead cylinder. How ever no I have oil getting blown in to the cold intake. Looked to replace the pcv valve and there is not one in the vechile. So they ran a pressure test and said that the cylinders have compression where do I turn now. I replaced the rest of the plugs and it seems fine but with oil going in to the intake it is just a matter of time before it screws up again. Just had the oil changed 1500 miles ago.

Something had to get into the cylender to crush the electrode on the plug, or you have a bad wrist pin or connecting rod bearing. Were the electrodes bent shut or broken? As far as oil into the air filter, there has to be a breather from the engine to the airfilter. Even if there is no PCV, there has to be a hose leading to the filter box from the engine. Otherwise, there couldn't be oil getting to it. At work tomorrow, I'll check if a ram with a hemi is there or if one comes in and look at it.

Just an after thought. Have you ever heard any rapping, knocking, ticking. From the engine?

One plug was bent shut the other was bent shut with a crack in the plug. Also the ceramic at the bottom of the plug was broke. I am assumin that the ceramic broke and then it was beaten against the plugs. I dont know never heard a knock or ping or anything like that. I was told today that it is almost impossiable due to the hemi head set up for the piston to hit it. As for the oil there is a line that runs from the oil fill cap to the air filter. But there is not a regulator in there or anything. I am going to change the oil in it tommorrow because like you said with a dead piston fuel has to go somewhere and could have thin the oil. Doesnt smell like it but why not finish the tune up to double check. The line and when you take the oil filter cap of has white smoke or steam coming from it while it runs. Also I can plug that line from the oil fill cap to the air filter and it will build up pressure in the line so maybe the oil has fuel in it and has thinned it out so much that it is coming to the top of the engine. Not sure but that is my next step on the tune up if that doesnt work it has to be something internal in the engine and dodge will find it or I will strongly encourage them.

Ok I changed all spark plugs, oil and filter. Reset the check engine light and in 50 or so miles the light came pack on and says miss fire on cylinder 6 the same one that had the crushed plugs. The plugs are fine and produce spark. Now I have milky white oil coming in to the intake from the oil fill tube. The oil how ever looks fine looks like what I put in there 2 days ago. But there is water on the top of the oil filter cap (inside it) and it looks like more than condensation. I also sprayed seafoam (2 cans) in to the intake to clean all the other oil from the blow bye out before the plug and the oil change. What do I do now because the money to fix this issue is getting low and the patience. Spent 200$ and another 100 to take it to dodge and nothing is working ANY IDEAS. It has had a full tune up so thats not it where do I turn now does it sound like a head gasket?

Based on the white oil and the top of the oil cap, I have to say yes to the head gasket. At least that is what it sounds like. I'm glad to hear that the new plug didn't get smashed like the old one. I'm questioning if coolant got in that cylender while it was running causing the damage to the plug. Coolant won't compress. I've seen it bend connecting rods. If I recall, you did check the compression and it was okay. Am I correct on that assumption? Also, now that the light is back on, can you feel the miss again?

The dodge dealership is the one that told me that they ran a static compression test on it and it was fine. He told me also that he could not run it with a hand held because he had no way to plug of the other hole. I thought just leave the other plug in? But whatever. As for the miss no at idle the dodge will vibrate more than usuall. But if not yours you prob wont know it. Had it 5 years so I can tell. But will gain rpms with no sputter just fine

The only thing I can think of then is a possible head gasket allowing coolant into that cylender and causing a misfire.
