I was under the car changing the oil pan (rusted enough to leak) and I saw one of the nipples that press into the block (actually the lower oil-pan) right next to the thermostat is fairly rusty. I have confirmed subaru cannot get the part.
Anyone ever replace one of these somehow?
I assume if no replacement is available I would have to remove the bad nipple and tap the hole for a threaded nipple (hmmm, steel or brass?), unless I could get lucky and find some steel line (big brake line?) that could be a decent press-fit.
Tapping the hole for a tapered nipple would be nerve-wracking, given how thin the boss in the casting is right there. Would also have to make sure it didn't introduce a restriction as the only coolant flow before the thermostat opens is through that line.
