I had a Christen inverted oil system on my RV-4 (320-E2A), and recently removed this. I removed the plug inside the sump and put in a new proper length screen. The "to" oil cooler line is at location "B" on page 5 of this document http://www.yeeles.com/Reference/Hi-Temps.pdf
After doing this and ground running the engine I find I have an oil leak - ended up with a 4" puddle under the accessory case. May be coming from the Type 2 Thermostatic By-Pass valve as shown on page 2 of the above document, or may be coming from the oil filter. The oil is clean so hard to tell exactly. I did not change the filter as there was only 5 hours on it since the last change.
Oil pressure is steady at about 70 psi, even at idle.
My question is, are there normally some other modifications with a Christen system that I need to reverse? I am wondering if I am getting extraordinary pressure in the system somewhere.
