Gil, I just sent the club site the Part # 4318-039 for manifold heat risers. It has graphite or molybdenium in it. Works better than anything I have used.

It did not, so we agreed it probably was not what I was looking for. He claimed that was the only product they had that could be likened to what I was asking for. I didn't think it--- without containing something like graphite that would remain in the heat riser area--- would work any better than the numerous other "penetrating" products on the market, so didn't buy it. 300ly, Gil In a message dated 6/14/2006 11:38:22 AM Eastern Standard Time, c300c@xxxxxxx writes: Hello everyone, Chrysler dealers still have the manifold heat valve penetrating oil and lubricant in a spray can. I don't have the part number as my stash is 2000 miles away. It's a much later number than # 1879-318.
