Lycoming oil cooler line connection

[cdeerinck]

Can anyone give me specifics on the 90? fitting? Is it not in the FWF kit? If not, can anyone provide a source and part number?

How does Vans suggest this connection be made?

How about this approach? I switched the temperature sending unit with the AN fitting for the oil cooler hose, and now there's room for the breather fitting, too.

Standard AC-type filter adapter? Bad move. The cooler is out of the circuit, as you've plumbed both lines to the downstream side of the vernatherm. Worse, when the oil gets hot, the vernatherm will try to close the bypass hole (as it should), and pressure will drop. The relief spring on the vernatherm will probably save the engine, as it's a positive displacement pump.

And there is no flow where you put the temp sender.

Back to the drawing board (and trying to remove the plug down below. Thanks for straightening me out on this!

Sorry for the delay in getting back to everyone. I found a good deal on a stainless steel breather fitting (45 degree angle) that allows me to use the alternate oil cooler line port. I tried repeatedly to remove the plug that is between the mags on the accessory case, but had no luck, so I went back to the alternate location. Please see the attached image and let me know if this looks OK. Also, there is a Vernatherm installed below the oil temp sending unit. Thank you!

Don't know for sure if that will work with the real engine mount and lord mounts installed. If not, the parts you need to make the banjo fitting are available from Lycoming. P/N AN-777-8d swivel, 71620 bolt and a an901-8 gasket and a 71623 washer. They are standard parts for the IO-360-A1A and were used in all Mooney installations of that engine. If you engine was originally in a Mooney that is likely why you couldn't get that center plug out because its been in there since the beginning of time...
Good Luck,
Mahlon

That engine did come from a Mooney, so I may end up needing those parts you referenced. Thank you for your excellent technical advice! I'll be sure to add a post if I need to go that route.
