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!

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.

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.
