The oil leak is coming from the front main seal. The crankshaft pulley is probably no good (VERY common). The oil pump resides in a cover located directly behind the pulley. There is a o-ring seal here that also leaks. When replacing the pulley we (here at the shop) ALWAYS change both of these seals. This is critical.If the pulley gets real worn if can break the oil pump and ruin the engine. If it sounds like I'm scaring you I'm sorry, but I can't stress this enough. The slow idling problem can be many things-incorrect fuel mixture, misadjusted throttle plate setting (known as base idle), the idle air control (IAC) motor which controls idle speed, timing could be way off, Coolant Temp Sensor (CTS) could be bad (VERY likely), bad Air Mass Meter (very expensive, try the CTS first-pretty cheap). The turnsignal problem is probably a open ground circuit, probably at the tailights themselves, check for corrosion at the plug going into the light assemblies. or crusty bulb sockets.Hope this helps.
