These were common on the 1st gen 4.7 engines 99-04 but the second and third gens are more reliable so long as you maintain them, at least from personal experience
Cut them in half, use a grenade 🤣🤣🤣 I have a 4.7 with nearly 200k miles in my truck and it purrs like a large kitten, very happy with it! Maintenance is the key to a happy healthy machine!
Typically the reason the rocker has fallen off is because the valve seat has become dislodged,dropped a bit and when this occurs it binds up the valve. The rocker is usually what gives way. Alot of times we find that the seat then reseats back into the head. With that said to reassemble the rocker is normally a temporary fix as the seat will eventually fall out again and either do the same thing or cause more damage.
valve guide seals fall out of alot of older engines... you’ll generally find them in the oil strainer screen; when you tear it down because the oil pump starved and so did everything else
It's obscene that Dodge even puts these motors in so many vehicles. Used to be they made a decent motor but got poor MPG, now they break down and only get 2-3 mpg better than the old LA motors.
It's commonly agreed among the Jeep KJ crowd that most of the problem engines have already destroyed themselves (3.7) by now. Most of these engines are rebuilt at least once by 200,000 miles, so owners shouldn't be worried about modding their vehicles as long as they know the service history of the engine.
How many vehicles with these 3.7 engines were sold and what percentage of them have had this failure that you're referring to? Do you know how widespread the problem is in real numbers, not hype?
@ Powertrain Products, I bought a Hemi off you guys awhile back for a 2006 300C, and I have been noticing that I only run 13 PSI oil pressure at idle (tops out at a little over 50, even during w.o.t. acceleration). Your videos say you use a "high volume oil pump" . I was wondering what the pressure should be at though; I know the general rule of thumb is 10psi per 1k rpm, but still, 13 psi seems WAAAAAAY low, especially for a "high volume" anything......
13 psi at idle on these with 50 at operating rpm is just fine. Remember the common misconception is a "high volume" pump equals higher pressure. But high volume means it circulates the oil faster. This does not increase the pressure. A prime example from a very generic engine would be looking at the 350 melling makes a m55-hv for high volume and a m55-hp for higher pressure.
Range rover drop cylinder sleeves, jeep (fiat) have poor quality engines! Toyota to expensive! Are there any decent 2nd hand 4x4s out there for less than 5 grand?
@@muffdiver777yummy8 I would Get a First gen Durango , like the 4.7 L or 5.9 L over the Blazer tbh. Better Transmission and those V8 Magnum engines are tanks with proper maintenance. My 01 Durango 4.7 L has 214k miles on it and still chuggin .
I have a 4.7 liter Dakota about to turn 250k, no issues.
I almost can't believe it myself!

Other than that though, the engine has been great so far!
so if i buy a new OEM intake , you should have no excuse to back out of your warranty then?

I have a 4.7 that is locked up is there a motor I can replace it with besides the same

Have you heard of a fix for the rocker arms just falling off, on the 4.7 dodges?

Do they all run the same headers
I'm taking a 4.7 mag. out of a 1999 dakota 4ad , will that engine firnd in my 2004 dakota 2wd
The 4.7 in the rams is the same as the jeeps and Dakota’s right?
Generally speaking, yes. However some engines have EGR and some do not so you would need to check for that.
Will a hemi 5.7 engine fit a 1999 dodge Dakota
It'd
be a tight fit, but its possible..some Dakotas come with 5.9s
Can a 5.7 hemi fit a 2003 4.7
Not exactly sure, however if you're swapping anyway I'd recommend a good low mileage old skool 318 5.2. Fucking beasts
No 6.1 ?
Does a 2005 Dakota 4.7 engine will fit a 2004 ram 4.7
SOTO'S yes
Does a 2012 charger 5.7 engine will fit a 2007 chrysler 300c?

Dodge engineer need to be fire they should have a recall on this engine consumer lemon
It is a problem engine for sure!
