Re: Perkins 4.108M DIY Rebuild -- A Narrative
Funny you should mention that...
All that residue is paint. Hard to tell from the early, pre-machine shop pics, but the inside of the block and oil pan were both painted with a very durable black paint. I've been contemplating whether or not to go to do it again.
Do it, your oil will thank you for it. Use the electrical insulating paint - all the engine builders I've ever read or spoken to call for it, not engine paint.
Some of your pics look like you still have casting sand in some nooks & crannies.
I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.
