Spent 8 hours chasing a phantom oil leak on a 6.7 Powerstroke

The customer said it was dripping from the rear main, so I pulled the trans in my shop in Boise. Turned out to be a tiny crack in the oil cooler housing up top, dripping down the back of the block. The whole job should have been a 2 hour fix, not a full day. Anyone else had a leak that sent you on a wild goose chase?

Yeah, that drip path is such a liar. It's crazy how a leak from the front cover or valley can make a perfect trail right to the bellhousing. Makes you trust your eyes less every time.

Ngl, that $12 gasket detail is brutal.

Classic case of the customer being the worst parts changer. They always swear it's the rear main. That drip path down the back of a diesel block is a total liar. You just did a full trans pull for a gasket that probably cost twelve bucks. At least you found it before you buttoned it all back up and had the same leak staring at you.
