Welcome to AF

Please include the vehicle year, engine, and options.

Some of the years had a single, multi-purpose flasher/relay in front of the glove box, while others had individual units for turn and hazard flashers. Other circuits are different as well, so knowing the year and sub-model should help.

The drain plug being the lowest point on the engine doesn't necessarially mean that is the origin of the leak. Best bet is to get underneath the engine with a nice bright light and look for signs of leakage aroung the oil pan rail, front seal (behind the pulley), rear seal (in front of the transmission), oil pressure sender, and oil filter. Your looking for nice wet oil. If you find oil in one of these spots you have to continue going up to the timing chain cover & cylinder head. You may have to start looking from the top down to check the intake manifold and rocker cover gaskets. Unfortunetly oil follows gravity and gets blown toward the rear so you have to follow the trail to the source not always easy to do especially with a 4 wheel drive. If this is a new leak and you just had your oil changed could be something easy like a leaking filter. If you can't see a source above the drain plug the gasket could have been lost or broken at the last oil change also, easy to fix except you have to drain the oil to do it.

This should get you started. Post back with what you find.

thanks, i will check these tommorrow or tonight if i can find a bright enough light... i noticed today that there was 2 main sources of the leak, the drain plug and somewhere about 6inches or so towards the front of the car from the drainage plug...

Go in through the wheel well and pull up the rubber flap (splash guard) so you can see the engine. I'm not sure about a '96 but my '87 had the oil filter mounted on an adapter that screwed to the side of the block. The adapter was notorious for loosening up and leaking. If that's the problem I think I still have a gasket for it.

Good luck,
