my 2006 Charger with a 5.7 hemi engine lost compression and then just died repairman said a valve dropped into the engine do i need a new engine?
after doing a diagnostic at a cost of $288 they recommended a chemical clean thinking that a valve was stuck. Technician said he believes its the #6 cylinder that is not working and after looking into the engine believes a valve dropped into the engine. He is recommending that the engine be replaced without tearing down the engine. The car is in Brentwood and the technician said they are used to working on high end scale vehicles and does not know enough about the hemi engine. Does sound like a good recommendation to replace the engine? the vehicle has 148K in mint condition kept all maintenance up to date!
does the engine turn over at all? normal? or faster than usual. did he do a compression test?
He said he got the engine to turn over and drove it a couple of blocks to test the engine but he said it pours out smoke and runs rough!
If it's pouring out smoke, it probably needs another engine. The low cost solution is it buy a low mileage used engine from the scrap yard.
A leading engine builder has charged that Chrysler’s 3.7-liter V6, 4.7-liter and 5.7-liter V8 engines are fatally flawed, leading to catastrophic failure shortly after the warranty expires. The engines are shared by the Chrysler Group’s recent powerplants in the Durango, Dakota, Ram, Charger, Chrysler 300, Jeep Grand Cherokee and Jeep Liberty. A new or rebuilt engine is a significant expense for an owner that loves his or her car – why are such devastating events occurring at only 75,000 miles? According to Powertrain Products (PP), a leading supplier of used, rebuilt and surplus engines, the reasons are twofold and caused by simple design flaws. Faulty valve seats According to the engine company, the original Chrysler design presses the valve seats into the cylinder heads. The problem results when the powdered metal the valve seats are made of expands, causing it to drop into contact with the valve and pistons, which leads to catastrophic failure. In this process the seat breaks into many pieces causing deterioration of the piston, cylinder wall, valve and cylinder head. This metal can even get into the intake manifold – if not cleaned properly, it can lead to a failure in replacement engines. Piston ring landings Again according to PP, a flaw in the engineering of the piston ring landings results in the engines running much hotter than they should. Coupled with what they call overly small drain holes in the heads and block, this overheating breaks down new oil, leaving sludge in the engine, ultimately blocking it. Consequent oil-starvation can lead to engine block seizure. That said PP has a vested interest in convincing owners of Chrysler products that the engine is flawed. The Maryland based firm is willing to correct the problems they have identified for $1,500. On the other hand, if they are right in their assessment, that’s considerably cheaper than a new engine. "Engine problems are showing up in Dodge/Chrysler cars at about the 75,000 mile reading,” said Eddie Symonds, CEO of Powertrain Products. “Let's face it, everybody expects the engine to run smoothly for at least 200,000 miles, which it doesn't. We consider this as a very early failure." Notably the firm makes identifying automakers flawed engines and undoing the mistakes their business. They also specialize in repairing flaws in the Ford 5.4-liter V8 in the F-series and Mazda 2.3-liter engines used in Mazda 3 and 6 models. "We are not another corporate-monster," Symonds added. "We strive to help our customers to get back up and running as soon as possible." In the response to a recent NHTSA recall letter to Chrysler, the auto group stated: “Chrysler Group stands behind the quality and safety of its vehicles. It conducts voluntary recalls when they are warranted, and in most cases, before any notice or investigation request from NHTSA. “Customers who have questions or concerns can call the Chrysler Group’s customer care line at 1-800-334-9200.”
