Good looking out I'm bout to rebuild my lil 02 ram 1500 4.7L. Had planned on adding a new air filter system and flomasters watching through until the end I see you did the same that was nice. One thing I hadnt thought about was replacing the whole engine coolant system all together. I had planned on paying to have the engine installed but seeing how thorough you were with the procedure I'm confident it won't be too much of a problem handling it myself. Going through powertrain for the replacement motor one of their videos explained a few upgrades that engine offers. I'm an electrician so this is definitely out of my comfort zone u really just gave out the game can't tell u how thankful I am to have come across these vids u made. Good work 👍 I definitely subscribed to the channel looking forward to seeing what comes next.
I had same codes and white smoke when giving throttle, I change my valve seal guides and it fixed the problem the guides was leaking off witch caused my white smoke out the exhaust pipe and witch made my codes react to that rich smoke ,everything has been great since they were replaced and no codes .
The 4.7 is a beast but costly to rebuild. When I first saw the timing chains it was crazy! They are kind of like the Ford 4.6. Anyways good video bro!! Looking forward to the rebuild
@@Bryan916 So do the Hemi's (6.1s Especially) Though I've talked with a friend who works on the R&D for Dodge and has her own 6.1 swap into a Dakota and she said that normally happens once the temps get above 250-280 and hasn't had much in terms of oil changes. I've talked with plenty of 4.7s owners and they are split 50/50 Though the ones like me who are happy with it still say this, "Change the oil regularly and don't overheat it" Those people who have that mindset have 250-350k miles on the original engine. Had mine since new in 2004, Oct of 2023 the truck will be 20 years old.
@@Bryan916 I'm the original owner of a 2003 Dakota w/ the 4.7 and it still runs fine @150000 miles, but I also have always swapped the oil/filter @ 3000 miles since new. My problem with the truck is at the other end. The 2003 and 2004 Ram and Dakota 9.25 rear ends had a known factory flaw with the clutch pack retaining clips where they would wear out then break and work there way out and start grinding into the housing throwing thousand of metal shavings into the gear fluid which isn't good for all those bearings. Had to put in new front/rear pinion / carrier / axles bearings. Disassemble then install the new improved clutch pack retaining clips in the diff then reset BL and pinion rotational torque. Big PIA and a lot of work is what it was.
I stopped watching and subscribed right when you put the vacuum gauge on. I had been lurking for a while but as soon as you put the vacuum gauge on early in the diagnosis, that sealed in my subscription. It seems that reading the signs that a vacuum gauge can give you (or even owning one) is now a lost art even though it can give you a lot of information and provide direction. Now back to the video.
Dang, after watching the rest of the video I don't understand why the vacuum gauge didn't pulsate around a lower than normal vacuum. It looked steady in the camera.
Brian H I was thinking the same thing, I should have got some type of needle fluctuations from the vacuum gauge. My best guess is that there was enough compression to produce a power stroke in each cylinder and compression wasn't quite low enough to Translate to the vac gauge or I might need a new vacuum gauge, lol!
bryan916 Either that, or if the vacuum port was too close to the throttle plate then maybe the proximity to the IAC port dampened the response. Heck I am just theorizing, great start though!
So mechanic told me no compression third cylinder and says it needs a rebuild. He's charging me 2000 for parts and 1200 for labor. I'm really debating as I know parts don't cost 2000
Keith because this engine doesn't really have a specific compression pressure. The manufacturer wants you to check by variances so I go back and forth to compare Left Bank to right Bank pressures to find the lowest compression cylinder.
