A leak. Is there anything else?

Low pressure in? The tires?

You still FAIL to provide ANY useful information, nitwit. Is the cooling system not holding pressure? Is the oil pressure low, and if so why do you think that? Gauges are often inaccurate. Is it the fuel pressure? I mean c'mon - throw us a bone here for chrissake.
