RE: [Chrysler300] Ram K Question

["John J. Hertog" <crossram@xxxxxxxxxxxxx>]

I agree with Don Cole (and not just because he's a lot bigger guy than me);
I've had and worked on many ram cars, and vacuum leaks at the junction
between ram manifolds and heads have never been an issue, even when the rams
have not been supported by elbows and heat tubes. I've even reinstalled rams
without changing the valley pan gasket,using a small application of RTV
sealant,  with no problems.  I would suggest that you check the mating
surfaces of the rams with a good straightedge, to make sure they are
straight and not warped. You may want to take them to a machine shop to have
them resurfaced - same procedure as resurfacing a warped cylinder head.

George,
I've had RAM K's since 1977 and never had a vacuum leak at the heads. Are
you utilizing the heat tubes or trying to block them off? If you're trying
to block off the tubes, you can use a freeze plug in both ends of the tubes
and mount them with the standard gaskets. If you're utilizing them, then
make sure you tighten the manifolds to the heads first and then install the
heat tubes. There are also supports for the exhaust manifolds that go from
the oil pan rail to the header. If the exhaust is sagging maybe it's the
reason the heat pipes need spacers etc. to seat. Just my two cents worth.
300kly,
Don Cole
                  
Hi, All,
 
When I had the rams on (before taking them off to rebuild the engine),
there were vacuum leaks where the manifolds met the heads.  This may have
been caused by the rams being off slightly from the correct angle, due to
various blockoff plates and gaskets I tried on the heat tubes.  
 
To avoid this problem from recurring, I'm looking for a way to seal it  
better.  Fel Pro has intake gaskets which go with their valley cover.   Is
this ok? 
 Or is there a sealer, other than silicone, which will form a  bead to fill
whatever gaps there may be?
 
Thanks,
 
George Clineman
