I just received my plenum kit from Hughes yesterday. Everything looked fine except for the intake manifold gaskets. They just look really really cheap, and has CHINA stamped on it, and still has gasket material left around the spaces where it was punched out. (not clean cut). No indication marks for front and back of gasket. The front and rear seals are fine i guess, they look kinda funny to me. Raised up on the edges but dips down in the middle kinda like a river could run through them. Never dealt with a dodge engine before so im not sure.

I hate that I paid $134 for this kit and no better gasket than that. The felpro has the blue rtv stuff around each port on the gasket. Should I go ahead and buy a felpro gasket, even though its another $22. I was worried about the gasket that came with it sealing properly. Did any of yours look like mine do. Ill get pictures if needed.

Lastly. RTV or not rtv on plenum gasket. (Hughes says none for plenum). RTV on entire intake gasket?, coolant ports only?, or no rtv at all? Ill be using permatex right stuff.

Any help appreciated I really need it. Thanks

 

Regardless of what comes with anything, I always buy Felpro gaskets for the install... oh, and Remflex for headers.

With good gaskets, the only place RTV should be needed is a spot on each end of the rubber gasket front and back of the valley.

 

I went for the felpro set and got the plate separate on e-bay, but I'd spring for the felpro's in any case. And yes, a LITTLE rtv where the gaskets meet in the valley corners.

 

Ill bite. I used em, havent had any leaks in a year half since install.

 

Felpro + The Right Stuff=Win

 

Is the aluminum plenum plate still available on eBay? I haven't seen them on eBay in quite some time. If so, does someone have a link as to where they can be found?

 

I know Hughes says no RTV or anything on the plenum gasket, but I used a very very thin layer of permatex on both sides of the new plenum gasket. I have read on other forums were the new plenum gasket blew out again not long after it was replaced. So I figured a little extra holding power with the added permatex was worth it.

 

You do see the plenum thread on top of the page right? This question is asked and answered numerous times in that thread also. Please read it, Thanks And no need to be looking at other websites, this is the best one if you want that magnum to work right

 

Also the bottom of the aluminum plenum plate looks like it was dropped and slid across the floor. There are some pretty good scratches on the bottom of it and is goes all across. its on the edges too where the gasket goesaround. Was worried about that sealing. Probably gonna call Hughes and talk to them.

Gonna go pick up some felpro gaskets.

 

Ok, all i really read was the first page. I'll definitely be sure to look over it closer. Thanks.
