I put my vacuum on the exhaust outlet, and blew air into the hole for the EGT probe I did the day before. I also spun the turbo by hand to try and pass through any metal savings.

I removed the brake booster so I could repair any rusting area behind/below it. I was right, it was quite rusty due to the brake fluid I'm sure. The question is, do I replace the power brake booster. Checking prices on NAPAOnline tells me no, too expensive but maybe I can source a decent shape on from a board member.



I then wire brushed the rusty area on the firewall, and applied Metal Ready. After about 20 minutes or so I rinsed it off, and then cleaned the engine bay a final time.

I'm toying with the idea of replacing my throttle plate (throttle body) with a larger one I have lying around, but there isn't much point unless I port the intake which would of course require removal of the intake and add further delays. I think I'll wait until I need to replace the head gasket or something at a later date.
