Dodge Magnum V8 Intake Plenum Pan Gasket Replacement
PS: Sorry for the silent film. After all the work, I forgot to add music.
If your Dodge Ram, Dakota, Durango, or Jeep Grand Cherokee (ZJ) with the Magnum 3.9L V6, 5.2L V8, or 5.9L V8 has been pinging during acceleration or under engine load, and using/consuming oil, then more than likely your Intake Plenum Pan Gasket has blown out and is allowing the engine's vacuum to pull oil from the valley (where the camshaft/pushrods are) into the engine, burning it and causing ping/spark knock. The plenum being one piece, instead of a separate upper and lower intake manifold, requires there to be an opening on the bottom of the plenum during casting since it's such a large piece of aluminum. The solution is to cover it with a pan, as such. The pan is made of very thin aluminum and over time it warps from heat, allowing the gasket to blow out. You can replace the gasket but since the pan is warped, it will only blow out the gasket again and since it's so much work, it's not fun to do it several times. Hughes Engines has a replacement pan that is much, much thicker and is the solution to the warping. It will not warp and the gasket will not blow out again. This is the kit that I used in the video/slide show. It was cold out when I did this a few months ago so I didn't take any video, just pictures. Sorry the video is silent. The kit for the 5.2/5.9 V8's can be found here: http://www.hughesengines.com/Index/products.php?partid=22220
and the kit for the 3.9 V6 can be found here: http://www.hughesengines.com/Index/products.php?partid=22078. By the way, I'm not endorsed or sponsered by Hughes engines, I just highly recommend the kit if you're going to put in the work to replace the gasket. If you have any other questions about the procedure or any other repairs or questions about your Dodge, Chrysler, Jeep/ Mopar product, just send me a message or leave me a comment.
This applies to all '93-03 Dodge Ram, Ram Vans, Dakota, Durango, Jeep Grand Cherokee with the 3.9L V6 (239), 5.2L V8 (318), 5.9L V8 (360).
As always, disconnect the battery, and be safe and careful with yourself and everything under the hood during this repair. Thanks for watching! Comment, Rate, and Subscribe!
How to tell if your plenum pan gasket is blown
This is an amateur demonstration of the Chrysler-recommended diagnostic
test to see whether the Dodge Ram/Durango/Grand Cherokee plenum pan gasket
has failed, as described in TSB 09-05-00. Issues of test sensitivity and
specificity are raised.
A common flaw seen in the Dodge Ram Magnum V8 engine (1994- approx 2003) is
a leaking plenum pan gasket. The gasket is said to be prone to failure
because the pan is made of steel, and the intake manifold is aluminum. With
the different coefficients of expansion between these two metals, and the
marked thermal change this area is subjected to, gasket failure is quite
common, leading to an internal vacuum leak and oil contamination of the
intake manifold. Failure of this gasket may lead to oil consumption, poor
gas mileage, pinging under load, and rough idle.
This is a demonstration of amateur effort, published in good faith but with
no guarantees as to safety or accuracy. Auto repair is intrinsically
dangerous and misadventures are to be anticipated and planned for. Do not
try this at home without professional advice! Any misadventure you
encounter if you should decide to try and repair your vehicle is your

1999 Dodge ram plenum repair
Fixing the plenum pan on my truck... its a common problem on 2nd gen dodge
rams. When the gasket blows it lets oil into the intake which gets sucked
into the cylinders... most trucks mine included were just re programed to
run diffrent instead of dodge fixing the plenum. After replacing my plenum
pan and intake gaskets, i have more power and it hasnt used any oil or
coolant in the past week.
SLANT 6 Mopar or No Car!
Mopars and very attractive women.....Mopars Kicking ASS! What more can you
If you like what you hear, come and visit me at CDBaby!
In case anyone is curious, yes, I've owned tons of Mopar products! There
is a SRT4 in my driveway right now. I've had Coronet R/T's, Challenger RT,
Demon's, 300's, SRT8's, I love em all! And I have no problem with other
cool Musclecars. I even own a Buick with a V6 that is fairly
quick......However....I loves me Mother Mopar!
I'm back in the old school! I have a "NEW" 70 Coronet R/T! Burnt
Orange/White interior numbers matching, bla bla bla bla!!! Will post pics
of it in my new Mopar song. Yeah, I'm doing another one, yeah I'm corny!
Actually 2 tunes. One, I penned back in the mid 80's called Red Light. It
was about my 69 R/T.
Bye Bye Transmission...
dan running his truck threw the mud out behind the barn. guess the
transmission was going to go eventually considering it had 200,000+ miles
and hauled horse trailers most of its life. but it drove in and it drove
out all on its own.
heres a little info about the truck:
1999 ram 1500
4 inch suspension lift
dana 60 front/ dana 70 rear
gutted cat into flowmaster muffler all 3" pipe.
tires are 35x15 interco tsl boggers on 16.5x12 MT classic wheels
We drive the 2014 HEMI Dodge Police Pursuit Charger & test it from 0-60 MPH (again)
( http://www.TFLcar.com ) The 2014 HEMI Dodge Police Pursuit Charger is one
badass looking cop car. You certainly don't want to see this police car in
your rear view mirror. Last year we got to ride in the Dodge Police Pursuit
Charger at Chrysler's Proving Grounds in Michigan. This year Nathan and
Roman got behind the wheel of the 2014 HEMI Dodge Police Pursuit Charger
and played cops and robbers. In another fun and informative TFLcar video we
not only drive the new Charger Pursuit but we test it from 0-60 MPH at sea
level to see if the HEMI gas what it takes to catch up with the bad guys.

How To Find A Vacuum Leak - EricTheCarGuy
Vacuum leaks are one of the biggest causes of engine performance problems.
This video is pretty straight forward in it's approach to finding a vacuum
leak. On thing I might mention is that not all vacuum leaks are at the
engine. Some HVAC systems run on engine vacuum and can cause a leak under
the dash in some cases. I've even seen vacuum operated door locks. Just be
sure to be careful spraying flammable stuff on a hot engine, you don't want
to take one problem and make it a whole lot worse. You can also use a spray
bottle with water to do this same test. It may not be as effective, but you
don't have to worry about spraying a flammable substance on a hot engine.
For more information on diagnosing engine performance issues, check out
this article I wrote.

Dodge Ram pulling out stuck big rig - HD
just before we left i got the chance to get some video of this guy pulling
out a stuck rig. it was sandy, and the truck got stuck on a bush, and
without a trailer the shocks don't really move much in the back, so a
couple wheels came off the ground. luckily there were tons of 4X4's out

98 RAM 1500 Intake Plenum Repair 5.9
This is an overview not step by step. I used the kit from Huges Engines and
was pleased with the new hardware included. Look them up for prices and
applications. The intake manifold gaskets, the ones that seal to the heads,
were not worth using. I bought Victor Renz gaskets. And wouldnt you know
it, the thermostat they included was no good. A replacement was cheap
enough, just aggravating to replace it twice. Once everythin was buttoned
up. No more burning oil, best of all, no more pinging under acceleration. I
went back to 87 octane gas and the sumnbitch payed for itself already.
