6-cyl folks - oil line check valve Options

[Optimusglen]

I'm in the process of installing my 6 and have come to the oil lines. My entire setup is planned as AN-12, and I see options for AN12 one-way check valves from a number of retailers.

One example: https://www.jegs.com/i/JEGS/555/150024/1000...KEaAnyVEALw_wcB

I have seen the threads on here and on Pelican about the Rothsport valve, but the price and the lack of AN fittings have drawn me away from it.

Is there some other reason that someone should fork out 300 for the Rothsport unit?

I'm with Mark Henry. I also installed a Rothport two month ago, tank would drain into sump in less than a week. Best, Mark

Search the threads on here, I did this on my factory -6 a year or so ago. Posted several pictures. Mine has factory oil lines and heat exchangers; it gets a little tight in there. Be very careful when looking at 'check valves', the Rothsport is not like the conventional check valve you would buy for a sump pump.
Yes it's expensive, what isn't on a six? But it works as advertised. I had to keep a turkey pan under mine before installing it. Six months of sitting and I would have 3-4 quarts of oil in the pan (still not sure where it was leaking from the engine).
Six months of sitting now and I might have 3-4 tablespoons of oil.
