I'm doing this now and watched a few videos on the job. This was by far the best. Great job keeping it simple but informative, will be checking out some of the other stuff on your channel!
What were your symptoms of the bad gasket, i have a 01 dodge 1500 with the 5.2 magnum and it starts fine but when i go to take off i lose power and it missfires and is weak and cuts out but not codes and there is a little bit of oil you can see when you look down the throttlebody? Any help would be very much appreciated!
Always nice having a garage to work in I miss that I’m hopping mine isn’t bad I’ll check this weekend if it is looks like a task for me because it would be an out side job😢😢 and it rains 24 -7 in Oregon.
Will the plenum gasket cause lack of power to the engine? My truck runs good. But it feels like when I'm on the highway won't respond even with the gas pedal on the floor. It goes on the speed but slow
That could definitely be part of it. If your pulling oil into the combustion chamber you’re getting an inefficient burn which could be robbing you of some power
isnt the crank position sensor easier to get to with the engine stripped down? I've never changed one but heard its a shitty job.ting ready to do the hughes plenum replacement and bought a cps figuring it would be easy to.
Yes, it would be much easier to get to it with it stripped down. I also thought about changing out the water pump and timing chain while I was at it given those would be easier to get at as well, but ended up putting that off for a later time. Good luck on changing everything! Hope the video helps!
I would double check your wires and the firing order to make sure nothing is crossed. Easy to accidently swap the wires in the wrong place somewhere and that will cause a lot of misfires. Hope this helps.
Were your spark plugs fouling up before you changed this out? I have oil down there and have to change my spark plugs about every 4 months, and only the 4 on the right hand side lol
it would be difficult if not impossible to do the job with all that in your way. I have everything moved to change the water pump and with everything out of my way I'm gonna go ahead and do the Plenum.
Yes, it definitely felt very sluggish when initially trying to accelerate like you are describing. I also did the spark plugs and wires while changing it out so that could have helped a lot, but overall after changing it out it feels a lot more responsive when accelerating.
It's been shown that generally the only thing needed for the plenum plate is shorter bolts. The bolts being too long actually bottom out and don't hold the plenum plate tight enough. Those bolts would be alot cheaper than the Hughes item.
@@wormer66 bolts are one time use torque to yield , they stretch when tight and are very brittle, if you dont break em on the way out youll likely break em torqueing back down
Holding up great and my truck no longer burns any oil. It’s been about 6k miles since I changed it and I didn’t burn any oil between oil changes. I use to burn about a qt every 1k miles. Power feels better and not as sluggish too
i need help bad i’ve changed my plenum and intake manifold gaskets and now my truck runs horrible i know i plugged everything in right but it had bad power loss and sounds like a helicopter and jumps bad at 40mph. HELPPPP
The first thing I would check is to make sure your wires are plugged into the distributor in the right firing order if you changed those out or unplugged any. Second thing would be to make sure the fuel injectors were set into the manifold correctly and to check for leaking fuel anywhere near it. Possibly could have broke one of them to cause the misfire. Last thing would to make sure everything was tightened down to the correct torque specs for the plenum and manifold. Hope this helps. Sorry to hear about the trouble you’re having with it. Worst feeling is trying to fix something and somehow making things worse..
@@SwanCanFixIt most of these things i’ve done with my grandpa he works on dodges and he is stumped also. it has new plugs wires distributor map sensor new injectors all that is new it ran great before then after we got done with the gaskets it went to 💩 it makes no sense but i appreciate your help if you know anything else let me know please 🙏
@@4.7.9_sneakz There was a TSB from Dodge about re-routing the wires so that they don't touch or only cross at right angles. Might be worth checking out. Lookup TSB 18-48-98. Unrelated, my Ram ran rough after changing the wires, plugs, etc. and it ended up being a faulty (new) ignition coil.
@@4.7.9_sneakz you sure you guys torqued the bolts cris cross multiple times to 12 ft lbs? another video said you can mess up by not going around enough and the front ones might be tight the back ones loosen up the way the intake sits down and pulls in place.
I noticed that the truck was very sluggish when accelerating before changing it. Since then it seems to have a lot more power and it’s not burning oil anymore. It was burning about a qt of oil every 1000 miles.
This engine had 206k miles on it when I did this. Should be able to get at least another 100k miles out of it now. $3,500 is probably not worth it if going that route with that many miles. If you do it yourself with the Hughes plenum kit and new coolant, that will only cost you about $250-$300. Not a super hard job just takes a solid weekend to do. Hopefully the video helps if you end up doing it yourself.
Everyone can save a bunch of money by reusing the stock plenum plate with a new gasket or sealer. The problem is the bolts are too long and bottom out which results in less clamping force on the plenum plate. Use shorter bolts or grind the stock one shorter.

Where are you located, and how much labor cost for you to do a 2001 Dakota 5.9..?

Great video!

Is unbolting and setting aside alternator, belts, pulley, etc. necessary?
it would be difficult if not impossible to do the job with all that in your way. I have everything moved to change the water pump and with everything out of my way I'm gonna go ahead and do the Plenum.
Did it feel like the truck had a parachute attached before replacing the plenum gasket
Yes, it definitely felt very sluggish when initially trying to accelerate like you are describing. I also did the spark plugs and wires while changing it out so that could have helped a lot, but overall after changing it out it feels a lot more responsive when accelerating.
@SwanCanFixIt mine wont even do a burn out lol
Nice video. Great job
Surprisingly my blown plenum gasket caused smoke on start up. I replaced the valve seals first thinking that'd forsure be the fix but definitely not
It's been shown that generally the only thing needed for the plenum plate is shorter bolts. The bolts being too long actually bottom out and don't hold the plenum plate tight enough. Those bolts would be alot cheaper than the Hughes item.
Any idea what size bolts😅
@@DemonCowboy1911 Just shorter than the stock length. An 8th of an inch might be enough. Just have to try and see.
Why not just add a washer to shorten the threaded part of the bolt?
@@wormer66 That might work if the thickness of the washer is enough to keep the bolt from bottoming.
@@wormer66 bolts are one time use torque to yield , they stretch when tight and are very brittle, if you dont break em on the way out youll likely break em torqueing back down
Hows it holding up still?
About to do the same this weekend on my 96 5.2

what was the problem ?
Did you have any performance issues you noticed before doing this?
I noticed that the truck was very sluggish when accelerating before changing it. Since then it seems to have a lot more power and it’s not burning oil anymore. It was burning about a qt of oil every 1000 miles.
How many miles on the engine? Mechanic said my intake manifold gasket needs to be done (for ~$3500). But, engine has 255k...

How do you know how short to cut them?

take cardboard or something to cover that radiator...
