an RX8er's rebuild thread
Well I took the leap and with SARX (that is both San Antonio and South Austin RX)
removal and teardown went fairly smooth but it looks like a significant event took place with the rear chamber (photos below)....soliciting feedback![Crazy](https://www.rx8club.com/images/smilies/crazy.gif)
I am certainly going to go with new housings due to cracks but there was no visival chrome flaking and very minimal pitting on only 1 of the housing.
This is a N/A build btw (next build will have boost with it)![Rock](https://www.rx8club.com/images/smilies/rock.gif)

Considering this was a reman with 40k on it, it is hard to know how the parts were when they put it back together. We do know when they put the remans together you get new bearings and since you changed the oil like clockwork using Castrol GTX 5W-20, we can probably say that the oil just didn't hold up all that well in this heat since there was significant wear on the bearings.
We also know you did not baby this engine either. I thought I noticed some Idemitsu on the shelf in your garage, you also premixed a bit right? The carbon build up on the rotors wasn't too bad. Also, that sludge in the coolant passage could have been due to oil leak through from that coolant seal as well. If coolant was leaking into the oil that would definitely affect the oil in a bad way.

Bit of an expensive build... but that's the right way to do it. Then change the water pump, oil pressure regulator and you're good to go.
I'd actually just call Paul @ Mazmart and buy an engine from them, it's probably going to be cheaper, more reliable and better built overall

Without measurements it's hard to say but i would at least relap the side plates, replace the front cover, housings and stationary gears. New bearings, seals etc.

yea there were a few questionable moments

You can either get fd corner\side seal springs or there's a manufacturer in the UK that also makes better ones, according to PhillipM.
