Can you put the oil cooler together wrong? I am simply second guessing myself. As you may remember, a shop burnt my previous OBS to the ground so I am super cautious at this point. I have the rear tab aligned in the rear assembly and everything is bolted up and torqued to spec. What if you switch the direction of the tube (I don't think that happened)? Does it matter? Getting ready to fill it and start it and don't want bad things to happen.
Thank you.

 

Sounds like you have it.

 

It doesn't matter which end of the tube goes to the front or back. If the tab lines up with the notch in the end cap, you are good to go.
