Rapid R...This is what it did while priming with drill & priming shaft and 3 qrts oil in pan with bottom of strainer 3/8" above the bottom of the pan (which makes the majority of the debris screen 5/8" above the bottom of the pan): oil pressure went to 50 psi,then gurgling sound started and psi slowly went down to 40 psi and we stopped the drill. Added 2 qrts more oil (5 qrt total) and had 50 psi constant with no gurgling.

???? Another question I have is this: With the pickup screen this "high" will solids collect at the bottom of the pan that will not be get suspended in the oil? I like to drain oil when it's hot, thinking I have the solids suspended in the oil and thus are removed when the oil is drained out.

The pickup is somewhat too high & yes you need that "extra"? qt to maintain psi. No opinion on the potential for it to crack beings it is suspended but just me I wouldn't sweat that but it is a legitimate concern. On the suspended solids as you said just drain it when hot & you might jack up the front to tilt the pan a bit rearward to get more out & it's a non issue, everything there will drain out. I've even tossed a qt or 2 of cheap oil at that point to flush more of the crudded oil out of the bottome crevices of the sump. Kinda OCD but thats me
