So i am currently trying to figure out where the best place is to put an oil return line on my K20 although i am not 100% sure where the best place is.
On the back side of the pan but how high up and where??

Or is there is a better place to place the oil return bung?

Perhaps a picture would help if you have done this..

Thank You

 

every turbo car i put together, i put the bung here. no probs at all. you can also tap the lower block if the motor is torn down but the top of the pan is well above the oil level.

 

what size fitting is that

 

That is the exact place i put mine.

I used a -10an bulkhead fitting with bulkhead nut. then cut the back of the fitting off.

 

1/2" NPT to 10AN
