45 minute high-intensity session last night
could have been something else, but that only takes about 5 minutes
Run outside, pull out water blaster, grinder, blow torch, protection, fluids in cans, air compressor, extension lead, hoses etc
Wire wheel the old silicone off of the sump flange
Get the water blaster running
Blast the living shit out of the inside of the sump, especially under the top plate
Hold it up to dry it shake and stir, etc
Pour alcohol into it, shake and stir, etc
Tip alcohol back out into bottle with minor water content (e95? lol)
Heat and blow flames at the sump until all alcohol had evaporated or burned away
Spray light oil onto all except the flange, smoldered due to general heat
Store upside down on top of block/head combo with cloth over the top and bung finger tight
Put all tools away properly
Phew! Head inside for dinner and wash hands. Not bad
Fred.
