RE: [Chrysler300] Leaky Valve Covers - G

["Bob Jasinski" <rpjasin@xxxxxxxxxxx>]

My experience with RTV on the valve covers of my G has not been good.  Mine
have RTV on them and are leaking like crazy.  I checked everything for
flatness, liberally applied the RTV and did not over torque the fasteners,
so I don't know why its leaking.  I believe both cork and rubber gaskets are
available, is one type better than the other?

Hi Richard and All:
 
I have had some success with the following:
    1. Very completely clean the valve cover, and  makesure it is flat
around the bolt holes.
    2. Properly apply the yellow (or black) permatex  weather strip adhesive

to both the cover and the gasket.   Probably a couple coats,letting each dry

before bonding.
    3. Apply two or three layers of permatex #2 gasket  sealer on the head,
letting each dry.
I think the problem with the B engine sealing in this area is at least
partly due to the fact the surface was never machined flat.  Anyway, this
is an attempt to seal the potential voids
    4. I apply a coupe coats to the gasket as  well.
    5. Assemble the cover to the head and tighten the  nuts carefully.  I
retighten---not too tight---several times over the next  several days.
I am sure others have there own ways, and will be interested in hearing
about them.  In my experience, the 6 attachment covers are not all that
much better than the four.
 
As for the valley cover, the smart money would say to replace it.  It  sure
is a lot of work to go thru again to fix a vacuum leak.  (I have  gotten
away with using the old on though!) Hope this is of some help.  Good luck!

Good  morning,

The left side valve cover is leaking on the G. Should I pull  off both rams
and replace the valley pan? The valley pan is only a year or so  old and has
less than 2000 miles on it since I last had it off. Looks like I  am going
to be able to make it to Carlisle. Before driving that distance, I  was
going to try and replace the VC gasket.

Next what are the various  tricks out there to sealing a 4 bolt valve cover,
especially on a ram car  where the intakes need to come off. 

Best regards,
