Attached a pic of one of the housings I did for my recent (and first entirely solo) rebuild.
I just did the common jacket mod, nothing super special. The only other thing I did thats neat is welded up the EGR holes in the exhaust sleeves and groudn them smooth. Take a good look at a housing next time you get the chance and take note of all the cavities that would be filled with (at WOT +1600F) HOT exhaust gas and soaking into the coolant as a result.
Don't know how effective that mod will be, but I'm giving it a shot nonetheless.
On the rebuild I'll do on the keg I'm swapping this one for, I plan to do similar jacket grooves (done with a dremel engraver bit on the drill press, nothing too special...) but with my newly found thin and LONG end mill I will add a piece of 1/8" AL to either side of the plug bore on a diagonal. I'll be cutting out a piece from center of the "divider/support" between the dowel bores and then notching the inside and outside edges to provide support for the piece. It will be a minor interferance fit and the sandwiching of the engine will also prevent it from uprooting afterwards.
Keep the discussion/thoughts going
