#127 of 292 Engine Problems by jlock Mar 12, 2007 (11:50 am)
I have a 2003 Dodge Dakota 4.7. I took it to the shop and they placed a 2006 4.7 engine in it. The engine runs fine when it's cold but It sounds like it's miss firing when it heats up, also the check engine light flashes until it heats up then remains steady.

A FLASHING CEL is considerd a very serious problem which needs immedeate attention.   You should try pulling the codes to find out what is causing the CEL. (easy to do with ignition-switch trick... search the forum archives)

#130 of 292 Play in steering column by rstrong Mar 14, 2007 (7:02 am)
My 2002 Dakota has what seems to be forward and backward play in the steering column. It is most noticeable when either coming to a stop or accelerating from a stop. You can feel it in the steering wheel it is like something is loose and shifting forward and backward.

Replying to: sunburn (Mar 13, 2007 5:29 pm) I don't think they did, I took it back they made some changes and the truck will run fine for a few days and then it starts running erratic again. It begins when I crank it'll turn over a few times before firing up, and then the oil pressure goes up slowly. Like I said it runs great cold. I thought maybe the computer wasn't compatible betwenn the years.

Replying to: jlock (Mar 12, 2007 11:50 am) As far as I can tell, there are no major differences between a 2003 and a 2006 4.7 motor. The 2006 will have black carbon fiber valve covers, very slightly different camshaft specifications, and a re-routed PCV valve vacuum line. If you kept the same exhaust system and the same PCM, you shouldn't have any problems.   My first suspicion is something got hooked up wrong. Look at the PCV valve again. It's not in the same place as the 2000-2004s.   Regards, Dusty
#133 of 292 Front Seal by ja812 Mar 18, 2007 (11:51 am)
I recently had a front seal leak that was repaired by the dealer but I found out when checking my oil that is was a quart over. My extended warranty covered most the cost and the dealer covered the rest after I told them about the oil which they changed. Will having too much oil cause this problem and should I be concerned about other problems???   Thanks 2001 4x4 qc 4.7 Replies to this message: bpeebles (Mar 18, 2007 12:21 pm) dustyk (Mar 19, 2007 3:16 pm) ja812 (Mar 19, 2007 8:51 pm)

Replying to: ja812 (Mar 18, 2007 11:51 am) My 2000 Dakota with the 4.7L semi-hemi V8 was showing "high" on the dipstick when I took delivery from the factory. (stone-cold engine) This is because of the hollow camshafts which will 'drain back' into the crankcase and can make it appear to have too much oil in it.   However - If I check my oil about 2-3 minutes after shutting of the engine... the dipsitick shows EXACTLY where it should be. (because the hollow camshafts still retain the oil)   The hollow camshafts also mean it is easy to overfill the engine with oil. If you do not allow at least 20 minutes for the oil to drain when changing the oil, then the camshafts are not drained. If, under these circomstances, one adds the specified 6 quarts of oil, the engine will be overfilled.   I hope this helps explain some of your questions about oil-level in the 4.7L semi-hemi V8 engine.

Replying to: ja812 (Mar 18, 2007 11:51 am) Just as an aside, yes, it is not good to run with a high oil level. Most engines will tolerate a little over, some maybe as high as one quart. But most will not. If the connecting rods hit or come close to the engine oil it will produce wild turbulence in the oil pan and cause air bubbles to form in the oil. The oil bubbles will be forced through the system and cause inadequate lubrication to critical areas.   Best regards, Dusty Replies to this message: ja812 (Mar 19, 2007 8:51 pm)
