Seized S5 na blew coolant hose overheated help
My s5 na blew a the heater hose and overheated. K removed coolant and oil. I lwt motor sit for 8 months due to school and work. I pulled motor this month and noticed it seized up. I used lubricant and was able to turn it thankfully. I tried to turn it two hole times but got stuck on the second rotation. Could the rust caused it to get stuck again?

yes, iron seal in an iron rotor + water = rust

Okay so I let it sit for a bit with wd40 and was ablw to turn it a tiny bit again. So its not completely seized thankfully. I removed the exhaust manifold and these are the only pics i was able to take. This is the rear
I was thinking the worst when it got stuck. I thought it was going to be all rusted but i was wrong. I think it's not a complete waste of time now.

At this point the rebuilder told me not to try to move anymore since I let it sit for a few months. Maybe one of the corners got stuck and is preventing it from moving anymore. I might damage it if I force it. Either way it'll require to be opened up for a rebuild. Heres hoping there's no major damage for a rebuild.

One of my housings from an NA S4 that overheated and blew the hoses off. Just driving on the highway and when I noticed it was overheating, in about 30sec the needle went from slightly past half of the range to 1/4 of the range beyond it and blew the hoses. Hope your housings fair better than mine. (the rotor was also destroyed)
Sorry the area of interest is a little out of focus.

Well one housing cracked and a main housing was not good enough to reuse. Luckily we found good used parts for a decent price.
