Hey question guys what company valve stem seals have you used? Any recommendations  

I have Fel pro on my 280. They were in the rebuild gasket kit at a local chain store. Working fine since 2011.

Nissan on my 240, also great since 2016.

 

Next question how do you recommend I flush the rust out of the channels. I can’t pull the car out side to use a hose and I don’t think it’s a good idea to use water with the pistons open right?

You should have done it before opening, but you can do it after you close it.. head on and clean the waterways.. I never had a clogged up engine but maybe someone here can say what to use besides lots of water..

I actually did do it but I guess there’s a lot of build up in there

next question 

what do the thing circled do?

Air conditioning magnet valves (solenoids) and vacuum reservoir.  Take care of those parts, and the hoses.

How do I take off the electrical connectors? I don’t want to break anything 😅

Are those connectors.. righty tighty lefty loosy?  You turn them to the left to open?  I've seen those conn. on headlights of the 260z..

I'm not sure but I think that you just peel the rubber boot back and pull them straight apart.  That's how other connections are up there.  Here's a thread with a picture of a set unplugged.

This worked! I didn’t peel the rubber back due to how brittle it was sprayed it with a little silicone before pulling

This is how I’m flushing the engine out.. hoa says I can’t do anything outside. 
 

so I got tarps and taped it so water drains out of my garage. Plugged all the holes and I’m using an air compressor to flush the system with water. I had put vinegar into the the system for a few days before doing this. 
 

look at all the hard Sediment that came out! 
 

I will repeat until I see no more color in the water then I’ll remove the expansion plugs and do a visual check and flush 

 

caution dirty water will go everywhere. 

For the pistons I put on blaster and a towel but I don’t see any other way around it. 
 

if any one has any ideas to help keep piston rings clean I’m all for it
