After daily squirts of pb-blaster and judicious application of heat to the block - I've backed out all but one of the corroded water pump studs. And the fourth one moved a little yesterday so I'm sure that one's coming out today.
944online sells a nice package of replacement studs, by the way. These studs are not listed in the PET.
Question: these penetrate through the block to the water jacket. The factory applied *something* to the threads - which certainly behaves like threadlocker rather than anti-seize. What do you guys think is the right goop for the job given the potential for corrosion and leaks? I'd normally apply a little Optimol TA.
