My 1995 Mazda 626 V6 is smoking under the hood around the engine. Not billowing smoke, but definitely smoke when engine is running and accelerated. No oil or fluid spills. Fluids are all full. Car temp gauge is not overheating. Battery was completely drained after parking it overnight following detection of smoke. Can you tell me what I should be looking for?

Re: 1195 MAZDA 626 V6 Engine Smoking
Hello! + 12 volts of battery is making resistive contact with ground...During day light...Look for burnt components in engine compartment...Use your sense of smell to help localize...If you do not see/smell anything...Charge or replace the battery...Inspect the + battery connection to the starter motor to insure it isn't close to chassis ground...Start the car after dark and look for sparking or arcing...If it begins to smoke...Zero in with a bright light to locate the burning component...Don't spend a lot of time doing this...Leave the + battery connection finger tight in order to remove quickly...Following this procedure should point you to the area causing the problem...

its time to look under the car yourself for a oil leak or even a plastic bag burning on the exhaust you have been checking the engine oil have you checked the transmission fluid level? the trans is on the drivers side i believe
Please provide more details for analysis like:
- what is the mileage on your car?
- is it smoking continously or only intermittently? How much smoke is it?
- what colour is the smoke? bluish or sooty?
- does it smoke when engine is cold or hot?
- is your car losing power?
- is your car consuming motor oil and at what rate?
- has the engine ever been overheated?
- is there an engine MIL ( malfunction indicator light ) code flashing on your dash? If it has, then you need to get the workshop to run a scan of the engine's computer to find out what the possible faults are.
- by the way, is your mx-5 fitted with a rotary engine or the common 4-stroke piston engine?
If it's the org. engine it will has over 150,000 miles on it. It's normal to has the valve seal/oil seal on the head to leak oil into the cyclinder. The smoke you see is the motor oil drop from the seals. It land on the top of the cyclinders and it create black smoke at start up. The inexpensive fix is to start using high mileage oil with seal conditioner. This will help soften the rubber seals and help reduce internal oil leak. The correct fix is to wait until it's time for a head gasket replacement and let the professional service the head. Complete head service is the only method to stop this internal oil drip problem.
You may have a oil or a coolant leak and it is getting on belts. try using a garden hose ans wash off belts and see if noise goes away than look for leak and get back to meI would be more than glad to help. Also your battery may be weak that why you would start this morning. Good luck and thanks for using FIX YA
I'm afraid you have a bad or blown head gasket. does it have water on the oil stick too? may not be worth fixing if this has gone on too long you may want to take it to a garage. is it smoking out of the exhaust.
if the car starts to overheat it can be the waterpump if it goes hot that quick. im not sure if the waterpump is where the timing belt of external driven off of the drivebelts but make sure all the drivebelts are on and check for any leak in the system.
