88 240 wagon, 160k Normally I drive 55 and I am very strict about it, but it was Christmas Eve morning and I wanted to get home so I was driving at 65-70 mph on my 1 hour commute. Engine dies without warning. No suttle or dramatic noise or feeling, just complete and abrupt shut down. Put it in nuetral, coast to a stop, engine cranks slugishly but will not start or even sound like it will catch. Upon towing car home, noticed an oil stain about 7in around and one next to it about 5in around, and wet enough to see it was oil if you wiped it hard with your finger. Checked oil level while stranded and it looked good. Did this while in panic on shoulder of main highway with my world crashing and visions of me being killed in some freak Christmas Eve accident. Have not checked sinc I got it home or been under to see if theres a hole in my engine. Known and suspected problems: In tank pump is dead, and I have been running on main fuel pump.(no power, poor to no acceleration) Rear main seal leaking a quart every tank and a half of fuel.( oil all over bottom of car from tranny back). I stay on top of oil level. Three weeks prior, I lost heat and drove for at least 1 hour each way on two commutes (total of 4 seperate hours), thinking I had a faulty heater control valve (Hose going into valve was hot, hose coming out was cold). When I replaced valve noticed I did not get much if any coolant upon disconnecting hoses inside car. Finished install got no heat, saw no coolant in overflow, added 1 and a 1/2 gallons coolant, got heat back. (check the easy things first, I could have checked coolant level when problem arose, but looked for something more complicated and costly) Noticed then that O-ring on water pump was seeping, not dripping, but seepage was there. Started to maintain water level in overflow. Leak did not seem dramatic, and ordered new gasket set for replacement. I have never heard or read of a low oil press. shut down feature , is this wishfull thinking. Have I neglected my car to death. Ray
