LS1 Water Pumps

[Foscheck]

Has anyone rebuilt one or had one rebuilt? If so, do you have a preferred vendor?

i have rebuilt one, it is a pain,  it takes the same inner seal as a SBC, so you will need to purchase a SBC rebuild kit to get the seal, if you can get a new pump might be better, 

I had to weld a nut on the impeller so i could get it out with a puller, than cut it back off, I did not replace the bearing just the seal, was a huge time consumption,

Good feedback. Thank you
