Three extra notes;

I *may* not have been very religious about checking my oil level, I since read that Japanese engines, generally, are built very tight, and are sensitive to oil levels. This may have been why my bottom end decided to go?
I am sure history of headgasket problems did not help here. I think I was losing a bit of coolant.

You can have your engine oil tested for contaminants like gasoline, coolant. I did not know there were 'consumer" labs offering that. Very useful to investigate coolant loss,loose valves, etc. Useful to buttress claim for warranty work.

CL people are funny: iI posted the car for sale "Subaru with dead engine" and "not running!" in body text. Someone replies "Anything wrong with it?". There is no way to tell if the responder means "anything else", or just didn't read the ad... or is on a physing(sp?) expedition!
