Oil leaking from front of the car

No, you should not worry. Tail pipe dripping isn't related to your radiator. It's common especially if your vehicle sits alot.

Small oil leak. You need to find the source of it. Use some good engine degreaser and clean it up. You should then be able to find where it's coming from as you fire it up and check around. I understand sometimes that's hard because things are packed in. How fast are you losing oil? Check the level on your dipstick.

clean the engine and check where it is coming from. Is it at the front of the rear> do you smell burning oil when you switch off the engine? Clean an area under the engine compartment and see where the oil is dripping from and get back to us. Typical places for leaks are the valve cover gasket, oil filter housing bracket.

Yes, your water pump attaches to the front of the engine block. If a leak opens up between the two, coolant goes into the crankcase along with oil. That means water and oil are being circulated through the bearings and cylinders of your engine. Don't drive it in this condition.

Could be oil dripping from the valve cover onto the exhaust pipe.
One drip can cause alot of smoke when it hits the pipe.
Could be power steering fluid too.

1. External Leaks
You need to get the vehicle to a mechanic to check all flexible coolant hoses, hose connections, around the exterior of the water pump and the entire radiator. To do properly the vehicle also needs to be on a hoist. If there is an external leak you should find coolant dripping from the front of the car while the engine is idling and the cooling system is fully pressurized. However it depends how bad the leak is and it's location.

2. Internal Leak

If coolant is leaking into the engine this is a serious problem and needs to be identified by a competent mechanic. For example, if you have a blown head gasket coolant will blow into the engine and contaminate the engine oil. If you check the oil in the engine's sump it should be completely free from coolant contamination.
You should also check the coolant in the radiator for any signs of oil contamination. If there is coolant in the oil then there will also likely be engine oil which has blown into the engines coolant passages and then mixed with the coolant.
IF you can find traces of coolant in your engine oil (or oil in the coolant) the likely problem will be a blown head gasket and the head on the engine will need to be removed and inspected .

Blown head gaskets are usually a result of an owner allowing the engine to overheat as a result of low coolant level, failed water pump or faulty thermostat. Overheating can also cause major damage to the head on the engine.

Have your valve seals checked, Mits is back on valve seals leaking and burning oil.

OK, 4.3 V6 ? Coolant leak is coming from under the oil fill cover ? , do you mean the oil fill tube ? Could be a bypass hose is leaking, or a manifold gasket is bad, need more info maybe, pics

It's either coolant or oil if he put dye in to find the leak

might be the thermostat housing to as its right above the water pump. the best bet would be to pressure test the cooling system and inspect to see where its coming from

your water pump is leaking and most likely you had a small oil leak under there also and now the coolant is washing it out, don't go too long with these leaks because your timing belt is under there and is getting soaked with oil and and coolant this will break or slip off causing major engine damage to result (i.e bent valves) good luck and please rate -jeff
