Low oil pressure and clouds of blue smoke when driving just 30 moh

My maroon 420G had its engine rebuilt by VSE about 5 yrs ago. Has performed brilliantly in all respects until recently. First the Pertronix ignitor died. I replaced it, and now have a problem with the AED/hisser which won´t come off by itself or me turning the ignition off and quickly, as I always do.
What´ s more, the idle went up to 1800 even with the hisser turned off by pulling the wire. I then drove it a mere 3 min, with tons of blue smoke clearly seen through the mirror. I then saw the oil pressure gauge, which has always showed max/60 when cold, just pointing at 20-30.
At low speed, getting the dar back into the garage, it showed just 10.
What the hell is going on…?

Eeek… sounds like the crankcase has filled With petrol!

Drain it, refill, and see if that doesn’t bring the pressure back up.

this happened to my 420G, just another reason to hate on the ASC

check the oil dipstick, if its way overfull, that will be the culprit

In my case, I did have a manual switch, just forgot to turn it off

the OP sender is a wretchedly unreliable item as well
