Getting ready to open up a blown jspec, like to guess on what is torn up?
I've got a blown jspec from one of my customer's cars. His oil cooler lines let go while on the highway, and (he says) he saw the pressure drop and threw it in neutral and coasted to a stop. After stopping then he turned it off. (!) What I've got is 90-90-100 off the front rotor and 0 off the rear on any faces. With the loss of oil, I'm thinking he may have blown an oil seal which could explain the crankcase pressure while compression testing.
I'm pulling it apart, I just wanted to see some opinions and pre-diag.

Keep Right Except to Pass
I tore apart an oil starvation case once and the bearings had deteriorated to a point where the rotors were colliding with the side plates. So bad they had galled up the plates and welded the side seals in their grooves. IIRC the rear was much worse than the front.

I'll bet he heard the rattle first, then felt power drop, then saw the 0 oil pressure, then shut down..

That way all those morons that own rotaries and don't check their oil every other fill-up can stop killing these wonderful machines

*gasp* You only check your oil every OTHER fillup?
Of course, I'm premixing, so it's more of the "Yup, it's about a quart high, time to change the oil." check.
I can see someone noticing if the gauge were to fairly rapidly drop. It moves fairly quickly, and I'm willing to bet that in normal highway cruising if one of my gauges dropped to 0 I'd catch the motion in my peripheral vision and see it within 5 seconds.
However, "Engine off" is the good failsafe to use when something like that goes wrong.
When you get it apart, pics?

Should have written "and (he says) 'when' he saw the pressure drop 'he' threw it in neutral and coasted to a stop. After stopping then he turned it off. (!)
Who knows who long it was on zero???
Who can get away with checking their oil every other fillup??? The way mine was burning I would stop at Kmart and buy a case of oil, put some gas in every other quart!!!
The buzzer goes off when you are almost 2 quarts low and you sharply turn right. If you put in two quarts you'll be just over the full line. The way mine was burning it that meant I could get home from Kmart and the oil level would be just right.......for about 75 miles.
