I just recently replaced my sp 12A (lost compression) with a stock 12A. It was running the "bee hive" cooler so I pulled it already and am running a front mount. Can the hard coolant line that's still back there be unscrewed and that port plugged or ...? I didn't want to attempt to remove it yet and potentially shoot myself in the foot and introduce a new problem that didn't exist. Right now I've capped both openings but they're still leaking a bit.

Here's a picture of what I'm talking about with the orange arrow pointing out the hardline I'm referring to. (it's not my engine in the pic by the way):

 

Are you wanting to remove it completely? Typically those of us who go to the front mount oil cooler will just cut the "T" portion off, then run the heater hose to the part of the pipe that remains.

I've never tried to remove one, although I'm sure it's possible. Not sure what you'd plug it with though...

 

The rear pointing one goes to the heater. I converted to FMOC also and capped it but havent fired mine up to see if it will leak.

 

I probably aught to run a heater core and see about getting some heat in the cabin for when I do want to drive it in the winter.

I found this thread and it helped answer my question even further. Thanks y'all.
