EA82 Cleaning & Assembly Questions

[SuspiciousPizza]

I'm doing a top end rebuild and reseal on an EA82 that'd been sitting in a car in the woods for 20+ years. 

The heads need resurfacing but once they're ready to go back on, I'm curious about oiling the head bolts. What's your preferred method and oil/lube? My first thought was engine oil but how best to apply? Use an oiler bottle? Just dunk the threads and shake off a bit of the excess?

Tangentially, for the Felpro head gaskets (they're what I had laying around from a reseal kit I bought) they say they're 'permatorque' do they REALLY not need to be retorqued? Would going through the FSM -60°, oil threads, retorque, repeat really not make a difference? I find that hard to believe. 

The engine was stored with oil in the pan, I'd like to fully clean out the pan to get all the old oil and crud out of there. Should I use something like diesel to flush out the pan? Any preferred methods?

I'd like to flush out the coolant passages with distilled water once the engine is back together (before installing). I was thinking of using an aquarium pump in a 5 gallon bucket with some sort of filter/strainer system, removing the thermostat, and letting it run overnight to get all the old nasties out of there. Or would it be just worth flushing the system with a chemical flush while driving around? 

Any thoughts are appreciated, y'all have more experience than I do.

Thanks :]

I was a long time ago that I did an EA82 headgasket job - I don’t recall there being instructions to back off the head bolts in the process! 

Just use engine oil, nothing special required. If you dip the first 5mm of thread that should give you heaps of oil to play with. 

If you can use an engine stand with the cylinders vertical (engine 90° rotated), this will help keep the oil in the holes and not on your new head gasket. 

Oil pan, drain it. Then pull it off to clean it out. Reseal with quality sealant. 

Cooling passages - you’d probably be better off hitting any passages you can with a high pressure washer before starting any real work on the rebuild side of things. Just running water once the work is done won’t move anything. 

If it’s looking really nasty, getting a rod or a screw driver in there to remove scale can be effective. Ensure you get this crud out. 

When putting everything back together, clean all mating surfaces then wipe with methylated spirits or some alcohol wipe that completely evaporates without leaving a residue. Then apply your goo or gaskets etc and torque to spec.  

After about six months of continuous driving, it should develop an oil leak if you’ve done things right. EA82s always leak oil!
