Post by: califkid_66 on Thursday,September 23, 2021, 09:35:32 AM

I don't know how stressed that part of the casting is but I'd be tempted to have it welded up.

Are you sure it's a crack?  Looks more like a casting mark.  Welding will distort the housing such that it "may" require machining true again.

I agree with JB. Looks like a casting mark. I wouldn't weld it due to heat distortion.

I’m coming around to JB’s and Swift’s opinion. It does look like a casting imperfection and if it’s not leaking why try to fix it? It’s almost surely been there from the beginning so it’s been doing its job for how long?

DO A DIE PENATRATION TEST , TO CHECK FOR A CRACK, VERY EASY TO DO,  YOU APPLY A CLEANER, THEN SPRAY PENATREANT , THEN CLEANER, THEN DEVOLOPER, IF YOU SEE RED , ITS A CRACK
