Cracked case?

[Banshee802]

Noticed some oil on the bottom of my motor the other day. Is this just casting or are these cracks? Anyway I can fix if they are cracks?

Looks like cracks to me. It can be fixed but you need to pull it apart

Guarantee those are casting flaws. Is your premix red? What color is your trans oil? Is it dripping from the drain holes in the case?

Running ams oil interceptor and for transmission Rotella T. Of course I pick the oils that are all the same colors. So you think theyre just casting flaws? Not leaking cracks? I didn’t have overflow tubes on my carbs for a while so the residue might be from that.

My uneducated hillbilly input,  clean it all good, run it, keep eye on it for any leaks to determine if its crack or flaw.    If it was a crack, wouldnt a leak down test show ?

theyre probly just casting marks. otherwise oil would be pouring out. some fellers grind all the marks smooth so theres no chance to develop into cracks later on

Looks pretty clean to me. I'd say they are casting marks.
