I live in MN and it is currently -40 outside. I notice my car making loud noises when I start it. This just started once it was below 0 outside. At first the oil light indicator came on once the car was warm it went off. I went out of town for 3 day once I returned I started the car and it was making really loud noise and several indicators lights were on and they all went off once the car was warm. Today the noise did not go away after running for an hour. I checked the oil and it is fine. The engine light is still on. Please help

Could you give me a more detailed description of what kind of noise it is? Is it a bang like a gun? A thump or 'clonk'? Or a machine gun like rattle? Is it as you turn the key or after the car has started? These details can help work out where the problem is.

Common Car Noises and Their Likely Causes Noise More Details Likely Cause Fixing It Clicking noise while turning Starts faint, gradually becomes more noticeable until very loud Failed outer CV joint (constant velocity joint) due to torn boot (most likely) or old age Replace either the whole axle assembly (recommended) or the outer CV joint Water pump noises Difficult to diagnose because of water pump's location Noise usually caused by damage to the bearings in failed water pump Only cure is replacing it. If possible do it at the same time as a timing belt replacement to cut down on labor costs Squeak or squeal from an engine belt Loud, high-pitched squeak or squeal Belts either need adjustment or replacing If belts only squeak when damp, they probably just need adjustment. If they squeak constantly, they probably need to be replaced Exhaust heat shield noises Rattle that you hear when car is idling Damaged heat shield Replace heat shield

Replace oil and oil filter the oil is clogged up and needs to be replaced, Replace oil with a High viscosity oil you require more lubrication when cold a good Motor spares will be able to assist you with the correct oil,The noise it makes is cause the oil is not lubricating the cranck shaft and bearings and hydraulic tappets this is like a rumble noise,Only happens when the motor is not getting a good lubrication Caution if this continues to happen the motor will start to run dry and seize all bearings starting with the cranck shaft bearings.try to get synt synthetic oil expensive but will work .But do ask where you are buying for the best oil for low temp weather they will assist.

i think flywheel or starter I would try starter first

Get it to autozone and they will do a code scan for free,and tell you what is needed to replace,,probly a ******* sensor of some kind,,,,,

ok exhaust smells tend to intensify in cold weather. your vehicle is using more fuel the colder it gets. once the engine warms up does the smell go away? if it does, then i wouldn't worry.

have the brakes looked at at your nearesr honda dealer or reputable repair shop. sounds like ur brake pad sensor is contacting ur rotor...

your heater core is bad. It will not leak very much anti_freeze but it will get worse. And can try a raditor stop leak but i would change it.

WHOOPS this does sound expensive and i suspect your suspisions are correct ? have you felt the sides of engine block around the areas just below cyl head for hole/ cracks or even a piece of con rod ?
