Yeah, I'm no pro as evidenced many times (look up my ball joint festival, it's a laugh) so if there's more evidence to prove a regular metal-gasket-metal seal works better, makes sense because maybe, possibly, the pressure/heat build up in that area could affect the viscosity of the rtv sealant. Ya know, I'm realizing that these dodges are known for strange things.

 

Not as strange as Jegs telling me they dont even stock the gaskets for the Mopar Performance Valve covers I got from them...they sent me valve cover gaskets for the older 5 bolt heads.. called them to get a return and they dont even list the gaskets.. dont ya just luv it?[:@] Gotta go shopping for valve cover gaskets!!!

 

lol, well did ya try summit? I'm sure someone has them, the 318 and 360 are popular blocks.

 

Yeah.. I laughed so hard, I think I hurt the guys feelings.. I'll find them.. no prob.. just blew me away that they have nice Mopar Performance cast Alum valve covers, but not the gaskets for them...or any for that matter for the magnum 360...very odd...I still almost think the guy didnt know what he was doing...oh well, still looking for thermal tape for the Gibsons anyway so I'll check around. Just hate having to send back a pair of gaskets...odd package size and all the pain of getting them ready for ship and getting them in the mail..[:@]

 

What was the part number for those valve covers? How much did they run you?

 

the valve cover gaskets can be had at any local parts store , also check the warren. with the gibson headers and the thermal tape cause that mite void it..

 

voidthe header warrenty?hmmm... anyone have anything bad to say about the tape??Also.. can anyone tell me if the lifters in a '97 5.9L are rollers? looking at replacements....summit has Mopar performance that say they are the service replacements for magnums.. they are roller lifters...part #DCC-5249862..I'm using HS 1.7 non adjustable Rockers so I was looking for stock replacement lifters to drop in since the intake was going to be off for the plenum.

 

I wouldnt use silicone on the metal gasket. After time the silicone will wear away, then you have that space where the silicone was that isnt be occupied anymore, thus causing leaks.

Any damage to the cosmetic appearance of chrome plating or paint, other than defects in material and workmanship, is not covered under this warranty.

just be careful if you do add the tape/wrap

 

yeah, I was thiunking that too... the metal gasket wouldnt set all the way with the sealent in the raised ridge.. then if after torqueing, after time the sealent happens to leave a spot for any reason, you now have a metal gasket with a void....still think a more flexable gasket would be key... maybe the felpro is the way to go.
Still thinking this one through.

Padodgeram.... Thanks for the info.. I just got out the warrenty info.. your right on the nose.....Mine are the stainless shorties.....and as headers go... most will have a problem sooner or later.. voiding the warrenty might not be a good idea....but the tape would be a huge help in the engine compartment..thanks for the reply....
