How bad is this 12a blown?

So I have a 84 GS stting in my shop.
It has a pinapple racing street ported motor, rb exhaust, no emissions, and now a new radiator. When the old one went, it took the seals with it.
I drained the radiator and got a 50/50 oil/antifreeze mix. Normaly when the coolant seals go I find water in the housings, and I did, a very small amount, but damn this is ALOT of oil and water mixed. This normal? I am crossing my fingers that a motor with less then 11k on all new parts isnt warped.

I think your dowel pin seals are leaking... the higher pressure oil leaks into the lower pressure coolant jackets. I got oil in my coolant when I cracked my rear cast plate.

I'd recommend at least a basic rebuild. Just buy the soft seal kit, tear it apart, check everything and reassemble it. With so few km on it, hopefully it'll all still be good.

I get gastek kits from Mazdatrix. They're around $100. It should be all you need on such a recent rebuild.
