when oil in a motor gets that all sticky and tar like deal
it takes a LOT of work to get it out, as it will junk up in places and just STICK and stay pretty tacking collecting and holding crap in it
some things I know folks to have done
one, BEFORE draining, they warm motor up with a heat gun or like ways, to TRY and get oil thinner so it drains better and cleans out better
if you already drained or tried to, this won;t work really
SO option # 2 might be flushing motor with something like kerosene, or diesel fuel, and sloshing it about a lot, pulling motor over with pull starter(NO battery or plug in motor)
and repeating a few times
I have also known a few guys that heated NEW oil up, and then poured in HOT oil into motor and let it soak in some and then drained and THEN flushed
once they THINK it seems OK
then do a real oil change(filters being replaced a few times with above)
and the n running up to temp, let cool, and do again, and then drain and repeat till they feel good all thick nasty oil and junk is OUT
and then again, do a full oil change
its not cheap, fun, or easy to do, but, it can save you from a rebuild or worse, if a lot of crap is in there! and or blocks a line with being all gunky and thick, that breaks loose and then stops flow on you!
you drop a ice cube in hot water, it still takes time to melt, and a motor starving for oil; it doesn;t take long for things to go bad FAST
