Sump off. Oil pickup is... epic.
So, looking at the block, it looks like the oil gallery runs like so:
and to another plug at the front:
I was hoping with the sump off I could get in at the back by going up the blue gallery, but unfortunately that is blocked off:
So I removed the plug from the side of the red gallery to get a better look at that side:
Annoyingly, that fitting is an M18 thread, which is exaclty what I would like the other one to be . I could put a M18 to AN adapter there, but then I would still need a way to block off the other hole and convert the 'outer' section to an AN fitting...
It seems that is a 4 way intersection with another gallery running up at about a 45deg angle into the block:
So I am a bit stuck for ideas. None of these seem to give me easy access to flush out any fillings that result from tapping that hole in the block .
Options I am considering are:
a) hacking up the heat exchanger with an angle grinder to remove all the stuff that gets in the way of the engine mount, and getting it welded back up with 2 -10 AN fittings. Would probably not look all that pretty, but it won't be that visible anyway
b) turn the engine on the stand so that that hole is pointing down, and tap it with the tap filled with grease, and hope that any filings either get caught in the grease or fall down and out.
c) try to make a plate of some sort that bolts on and blocks that middle hole, and converts the 'outer' section to an AN fitting, then screwing another AN fitting in place of that M18 plug.
d) / wrists
e) other ideas?
