Cat c15 oil leak from behind fan mount?????

as superhauler and grape ape says

 

So you guys are saying it’s leaking from the studs that hold the fan onto the front of the motor ? Mine has oil coming from up there after I washed it I can see it’s running from up there not the front main seal like I thought

 

they're also prone to cracking just above where those 2 studs are.

Put o rings on mine now 0 oil leaks haha n I thought had to do front main

 

Take the stud out and bevel the edge of the hole just a little and put a o-ring on it that fits the bevel and put bolt back in. Problem solved

Hi guys
I have an oil leak and I was thinking it was the front crank seal, maybe this is my issue too, can anyone send a pic of the studs that you guys talk about?
I took these pics a couple of days ago how bad mine looks like but when I check my oil level still on the max, I just changed it last weekend.
Thank you for the help guys and sorry to high jack this thread.

 

guys
Can anyone tell me where I can find the studs that holds the hub? I Went to dealer but because truck is too old they can not even find the pic on the system. Please help
