oven cleaner -- safe for engine castings?

Simple Green has a nasty smell to it, almost as bad as Pinesol, and the cleaning results have never impressed me.
I'm sure that you can buy Gunk products in Canada, and the heavy duty degreaser takes care of any baked on dirt and grime.
Just make sure to hose off any residue before it eats into the metal.

Hi Gerald, and Chris and all

just before I started the present 82 1200 rebuild, I bought a fresh 6.62 liter pail of Gunk Hydro Seal 2. Just about every part from the 1200 project that will fit has spent at least an overnight in the Hydro Seal 2. Would work really well on the cylinder head and barrels Chris is trying to clean, the stuff is about $100 a pail around here, but can be used over and over and over..... the pail I just replaced was several years old. The only caution is that it makes rubber bits swell, you have to strip any rubber bits off whatever you are tossing in the pail, or you WILL have to replace them.

I brought a cheap $38 sand blasting gun and 25kgs of bi-carb soda for $30 and cleaned the hole motor with it with about 5 kgs left over. Worked a treat

Have had great success with that too, trouble is I ive on a main raod and the cloud of dust nearly caused a crash and the neighbours cars were covered in it. Switched to only doing it at night....
 
The the dust factor could be a problem if living in the burbs! Must admit the place looked like it had a dusting of snow, nothing a hose down didn't sort out. Not sure of the PH balance around that area is now! I like the fact it's water soluble, always dubious about grit blasting open cases even with all the oil gallerys plugged.
