Alot of you out there have the same Problem with the 4.7L dodge motor, and most will say its sludge or carbon build up. This might be the case in some but after years of research and alot of headach, I would like to tell you I think if you didnt run your truck too long when thew oil pressure dropped it can be fixed with alot of effort and a little money. I will post videos of my fix on you tube when im done editng it. So if you dodge oil pressure gage is dropping and you r affraid after reading posts that you have to replace you motor dont be thast scared yet...There are a few thing Dodge didnt do right when they made your truck or SUV. First they painted the inside of your oil pan(this is a NO NO) Second they u8sed a inferior plastic or poorly designed chain gaurd that tends to break off in your pan and clog your pump of intake tube. Remove your oil pan, wire brush the inside of the pan, clean out the pump and intake tube(or Buy new if you got the change), Flush the shiot out of it and change every 1500 miles with a flush 2 or 3 more times. This should take care of the issue(unless you did damage to the berrings or rods or have a diffrent Problem all togather). Then Go talk to a lawyer after you documented what DODGE DID!!!!! This is unfair and maybe done intentionaly....F U Doge why would you make it so hard to remove the pan WTF... Hope this helps alot of PPL please if this helps you and works for you...REPOST AT LEAST 1 TIME so taht we save some peeps 5 or 6 grand. Thanks. I used to love My Dodge I had a ram that had 400000 miles and still ran great, I have 2 rams now a 2002 and a 2003 and both r sitting cause they r shoit............

Engine knocks and rattles on startup. 70% of it goes away after 3 seconds and then light tapping continues for about 30 seconds to 1 minute in warm weather. Bought the car 2 weeks ago and they don't know what will fix it. 2 mechanics from other shops say it may be oil filter letting oil drain back into oil pan. That will be step 1. A Dodge mechanic looked at it and said its lifter noise, and it shouldn't be too much of a concern. I might think so too if I bought the truck 6 years ago and it was paid off. So far I can't get a straight answer about what it will take to make the engine right.

I am getting kind of worried because of the complaints I am seeing on the internet about the 4.7L engine with the same problem and I have not seen one good solution. I do not want to have the same trouble. It will make me sad because I love the truck but if they can't make it right I will have to return it. Luckily I have that option.

Update from Nov 17, 2010: Update: Doge dealer replaced the cheap oil filter with a mopar filter. No change.

Dodge dealer replaced the lifters. No change. Dealer has the truck again. I bought the truck from a dealer that does stand behind their product and said they will fix it to my satisfaction or I can return it so I won't freak out until I lose confidence in their ability to deliver on their word.

Update from Dec 24, 2010: The timing chain and tensioner were replaced and the knocking has not changed. Two dealers now say the noise is normal. I'm not confident in that answer so I returned the truck to the dealer for a refund.

Like the similar posts I have seen, this issue was not resolved, but the problem is no longer mine.

I bought this truck private sale. I lost the front axle shaft only 2 weeks after i bought it. I called to see if there was any recalls on the thing because it only had 50k on it. Found out even though I am the 3rd owner it was still under warrenty! Had it fixed for $100 at dealer. Never been one to deal with them before found them good. Then around 63k the friggin thing started to sound like it had a race cam in it. Fought with dealer a dozen times or more! They said that the rocker arm fell out of the engine block?! what does that? It was just losing antifreeze as fast as i could put it in. Overheated a few times. I kept bringing it to dealer, they would give me a junk dodge van to run while they called or came and got the loaner cause it wouldnt start, and said theres nothing wrong. The bastards at the dodge dealership in Farmington ME wanted me to get over the 70k mark.

I finally parked there one night in front of their front DOOR and left a note saying replace the heads and dont call me til you do so! They called and told me to come get the truck. They replaced one side and both side gaskets. Now at 97k the thing is knocking. I have a loud exhaust and you cant hear it over the knocking. Sounds like you are on the rollercoaster going up hill. I always liked the looks but other than that i would never buy another POS dodge

I had a noise start in the engine that sounded like a huffing, fluttering noise to me. A friend reviewed it and said it sounded like an exhaust leak and suggested I take it to Mieneke (big joke there). A guy that looked like he was just out of high school tells me it 'sounds' like the timing chain! HUH? Yeah right. I told him to leave the engine alone because he wanted to open the engine. I take it to another mechanic who held it for 5 days and finally tells me that it could possibly be the cylinder heads and/or the oil pump. He also stated this is a factory defect and that Chrysler won't step up to take the honors of repairing it. $3200.00 to repair the cylinder heads and the oil pump but once he gets in there it could be required I replace the engine for $5565.00 for a refurbished engine but the price could tally up if he began one job and ended up doing another! Do these idiots not know that money doesn't grow on trees???? So $112.50 for him to tell me I am screwed.

Now I am looking for another quote. If so many people are complaining of the same thing, why is a recall not issued? How does that work?

My wife stated the truck and the engine was knocking then the check engine lite came on. I had her turn off the engine and checked the fluids and looked for any leaks, I found none and the fluids were fine. She took the truck to the shop and they initially found the plugs on cylinders 4 and 8 were bad and replaced them then the coils. It still ran bad so they contacted Dodge and were told to pull the valve cover and check the cylinders to see if the rods had FALLEN OFF. They checked and the rods were sitting loose in the bottom of the cylinders.

Dodge told the shop this was a common problem with this engine and that they were well aware of the problem however they were not sure of the cause, they thought maybe it was an oil pressure problem bout there was no recall at this time. I was told this could happen again at anytime and if this repair did not solve the problem my truck could need additional, more expensive, engine repairs. So why the f--- don't they recall these engines now?
