Small Cracks in Case - Is This Normal ?
 

cleaned the gunk of my motor and found these small cracks. i'm not sure if this is normal or if someone overtorqued the case nuts.
any suggestions ?

Those are just casting marks, you should be able to feel them raised up.

i tought so but just wanted to make sure.
thanks

Ya, I asked the same question a while back.

would have sucked if the case was bad !!!!

Heh. This one comes up 1-2 times per year. I imagine it's scary if you don't know...

Darn! We ought to make it a point for the first responder to these to say that the case is trashed. Then wait 1 day before telling the poster we're kidding.

Would that be mean?

I verified there was no crack in mine by using penetrating dye:

my main concern are the ones that spread out from the case studs/nuts. they look like they spread from overtorqueing or something. one even looks as if it has a little piece that's chipping up.

I did that to another pelican when we tore his apart, had him going for about 5 minutes. It was not pretty, but funny as he!!

That's mean Donnie........

My favorite:

When I'm around someone I know will be assembling a bottom end, I grab an extra oil-pump seal out of my shop and carry it in my pocket. Then when the last thru-bolt is assembled I pull it out and say "isn't this the oil-pump seal?" :D ppl hate me. ;)

That is a great one, I'll have to remember that.:cool:

that's just plain cruel !!!
funny as hell though !!
