Just a guess, but if you are satisfied there is no leak along the stem, then I'd guess a head gasket next for doing flaky things, like leaking less when the ambient temp is warmer. Could be a crack in the head too, but not likely.
That hole has new stem seals, and the guides weren't loose.
If the head were cracked, I trust that would be apparent once it was removed? -- Jim _______________________________________ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
