HEAD GASKETS etc...
If you ever want to take your Cylinder Head off, and plan to leave the Block/Pistons exposed for some time, I found this works well:
Blow out the Pots Immediately once the Head is off,
Position the Pistons so that NONE of them are at TDC,
With Clean hands, take some fingers full of Clean Grease and carefully pack a 10-20mm edge around/into the Piston to Cylinder Wall corners,
Tear some small single ply strips of dunny paper and pat them onto the Grease - not too much paper, (this gives the Grease a more versatile surface (ie- allows bigger particles to be gently blown out when finishing),
Notes
1. If your Block is outside in the hot Sun use Hi Temp Grease.
2. Do NOT Rotate the engine until the Grease is removed (ie PLAN to loosen your Cam/Crank/Flywheel Bolts BEFORE Greasing IF you need to).
3. Push Clean Cloth into your oil Galleries (below Deck height, but not too far that they cant be retreived).
Doing the job this way allows you to:
"File" the Deck-flat as opposed to "Scraping" the Deck-not flat.
also by Filing your old Gasket off, this shows up any irregularities that Scraping dosnt.
After filing I use a small piece of Flat Glass (@100mm sq) and wrap some 600wet n dry around it and finish it off (dont double it up under the glass).
At this Stage your Cylinders will look filthy (dont panic, they are protected from the Dust, Wind and even Moisture for days)
When all is done, gently blow the Big particles out,
Remove the Dunny paper, then -
ALL of the Crap can be carefully wiped out using several small pieces of CLEAN cloth for each Pot.
Finally a slightly Petrold rag will remove the Grease residue from the walls.
This system worked well when I had to come up with a way to repair a Severely Dodgy Water jacket next to a Cylinder with "Quik Metal", but thats another Story.
Hope this hasnt bored everyone...
