Welding A Side Housing
#1
I was doing my first porting job today, and I blew it. I cut into a water passage right where the casting is thinnest on the top of a secondary port. This is for my FD and I really don't want to shell out $300 for a new end housing. Anyone ever try to weld one of these?
I don't see anything wrong with doing this. It is not a stressed part and its surrounded by good metal. I really just have to make it water and (some) pressure tight. I figure use a nickle rod with my stick welder. I'll try to get it done with the least amount of heating to prevent warpage. If there is any slight warpage, i was going to lap it anyway.
Is this a good idea, or should I just by a new one?

Damn that sucks. This is the reason that when I did my own ports, I kept the intake consevative, because I didn't want to shell out $300.
It may work, but better rotor motor builder's need to chime in.

I guess that depends on how big a chance there is of it failing. If the chance of the weld popping is very slight, I think I'll go the cheap route. I'm just hoping that someone has tried this before, so I have an idea of what kind of chance I would be taking. I mean, people use J-B Weld on internal parts. Seems like a real weld on a small hole would hold up fine in this area of the plate.

my machinest friedn once welded shut a break thru the water jacket on a rotor housing from an nsu spider motor once. they guy had extended the P port a little to high. I dont know exactly how he did it but it just looked like he built up the aluminum. im pretty sure it worked out ok.

I can't get a piture of it right away, but its almost in the same spot, but about 2 times bigger as the hole rx7tt95 put in his housing here: hole in housing
Glad to hear someone has heard of something similar being done before.
