Is this oil pan shot?
(the vein like cracks that you can see in the pics)
What could have happened to cause this?
How much is a new upper oil pan?

If it does need replacing should I trust in a
used one if someone has one available or just
buy a new one?

 

hmmm.. are you sure they are cracks?? Maybe casting leftovers?

 

unless you see oil leaking on the outside, thats normal casting remnants.

believe me, you dont want to replace that upper pan if you dont need it. I had to do mine. what a PITA!

 

You'll see those lines in aluminum castings, its normal.

 

thanks it felt kind of rough and just wanted to make sure.

 

+1 dont worry about it.
