A little hint for the 4.7 guys

[SmokedRam]

About a month or so ago, I would intermttently get a CEL for my EGR valve. Funny thing s, it would actually clear itself out and the CEL would go out on it's own shortly after it came on. Well, it came on again last week as I pulled into the driveway, I did the key dance and pulled te code, sure enough it was the EGR code. Next morning I went out...no more CEL, so..I did the key dance again...no codes.

So I said screw it and went ahead and bought the EGR valve from Advance. Got home, looked at where it was and said "no way I am doing that"...unlike the Hemi engines where the EGR valves are right in the front passenger side of the engine, ours is on the rear of the drivers side cylinder head.

So I called a mechanic buddy of mine, he said he'd do it for $40...I drive over and let him install it. He then hooked up his scanner to pull any codes, which none came up and he went ahead and reset the computer anyway. Took him about an hour to do, between us BSing while he done it.

Even though there were no codes, it's amazing the difference in acceleration and idle this engine has now. Definately noticeable.

Anyway, from what I have read, these EGR valves have a tendancy to fail or at least start failing between 45K and 60K miles...so, if you have a rough idle or slow acceleration, and you're still on your factory EGR valve, make sure you pay it a little attention.

Sure, I can take a pic of it...and where it is. I'll do it tomorrow for you all. After seeing him do it, yeah, I'd probably give it a try.

My EGR was replaced within the first 20k or so mile on my truck. I have 95k+ now. Might be worth looking into...

wheres that pic.? autozone has one for 95.00 seems a little high rocks got it for 60

 

[02Steve15]

Any pics?

 

[SmokedRam]

Sorry guys I forgot about the pic...but heres one I found on Google...





intoxicated, mine only cost $39 at Advance, then I used a coupon code to take another $9 off of it...So I only paid $30 for it.

Im about to do the 08 intake swap, is it a PITA to get to? What did you have to remove to get to it? I also have been told i need an 08 egr valve when installing the 08 manifold but after getting the used egr from the truck the 08 intake manifold came off of i noticed they looked very different. Was the old gasket hard to clean up?

the one i saw at autozone looked diffirent then the mopar but the mounting points and electrical conneticion were the same. it had a black canister on top. i didnt see mine back there on my 08 ill have to look again. the one autozone had looked like this

Well since the 4.7 was redesigned in the 08 model year, yours might be different...the one in that pic is a PRE 08 4.7...

And yes, that is the throttle body, mind you the 07-older 4.7 don't utilize an electronic throttlebody like yours does.

I think we still have the regular throttle bodies, IIRC, just the Hemi has the electric ones.

Yea i have the 07 4.7 and im installing the 08 intake manifold. But i do have the cable driven tb. I just had to buy adapters for the tb bc the 08 has 4 mounting bolts vs the 3 on ours.

The 08 4.7 and newer have the electric tb like the hemi but smaller of course.
