190e 2.6: retorquing heads, benefits?
Is there any benefit to retorquing the head on a 190e (1991, 71K miles) which has only minor oil seepage but more important the beginnings of a coolant leak, both in the frontal area. I have not seen any discussion of this--do the MB "stretch" bolts always maintain their torque? The exact point of the coolant leak is very difficult to pinpoint but I don't think it is the water pump or a hose. The leak (at worst, a pint a week) seems to go away after the engine reaches operating temp and having the cap on the expansion tank loose helps a bit too (otherwise car runs fine and within acceptable temp range). Thank you.
