My 2004 ford freestar runs well but is leaking about a quart of oil a week almost


If it's leaking from inside the engine then it would be coming from the valve cover. The cover gasket seal is no longer sealing properly. If oil is leaking down under the car then check around the oil pan, could be gasket or rear main oil seal or front oil seal.

What causes yellow gunk in the oil cap on my 2004 chevy trailblazer


Could be a leaking head gasket or intake gasket.
The gunk is water or coolant. Water if the engine never warms up, coolant if there is a leak.

I have a 2004 Chevy Trailblazer and it appears to be leaking something from the engine. It looks like oil and possibly another leak of coolant?? Any thoughts on what to check?


If you are leaking both oil and antifreeze there is a good chance you will be looking at a costly repair. The reason I say this is because things like this are common on blazers. Your problem is most likely one of two things. Either your intake gaskets are going bad or you are starting to get a bad head gasket. Sorry about the bad news. If you have any other questions please feel free to ask.

My mazda mpv 2001 coolant leaking somewhere. Filled it Saturday full line and is at low level monday afternoon.Where is it going? Van does not overheat


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.

Loosing coolant from reservoir, dye in coolant did not turn up any leaks, no coolant in oil, what now?


Either the coolant system wasn't truely full. Meaning that after it is filled up while running, the radiator will eventually empty in to the engine block, then you will need to fill it up again. Unless you are burning it up, but since it is not in the oil, then I don't see any worries
