Assuming that: - the oil pump moves a fixed volume of oil per rotation; - the oil level never drops so low that the pickup is even partially starved; - oil is not compressible; why is it that the system oil pressure drops as the crankcase oil level drops?

I have a feeling there is an exhaust leak putting fumes inside the cabin of my '94 Chevy S10. It does seem to have a noticeable smell, although not like antifreeze. Isn't there something I could pore into the engine while it is running which would produce smoke at any leak location, like the...

The heater blows air but with no heat what-so-ever. Basically, it's the same as the fan just turned on with-out...

I've got a 1992 Volkswagen Passat that will sometimes chug while in any of the drive gears unless you're going over a certain speed. It makes a thrumming sound and you can feel it chug, sometimes enough to make it stall. It does not do this in neutral for some reason. I've checked for air...

I'm just hoping to get possible ideas. My car won't start but ONLY when it's below freezing. It's been towed in to the dealer twice. The first time they said the engine fuse was blown. I expressed my concern that there must be something else wrong because fuses don't reset themselves as when...
