You might want to look at all the hot surfaces under the hood. it sounds like something made of plastic is touching something hot.

SOURCE: 350 chevy Lost compression and engine began to smoke.

pull out your spark plugs and try cranking the motor again, see if you're spitting out coolant from the plug holes. I'm asking you to do this, cuz it sounds like you blew a head gasket.

neither one of these would cause gas to leak. sure it is not coolant ? if you think it is gas it is not safe to drive car as it could catch on fire. possible cause would be a leaking injector.

SOURCE: When I turn the heater on burnt plastic smell from vents

It could be your heater blower motor or the blower speed regulating reisitor.
Try different blower speeds, see if the smell goes away. Also if one or more speed setting don't work, it is more than likely it is the resistor, if no to the tests, it is more likely to be the blower motor.
Also check to see if the blower intake is blocked.

Burning plastic smell when cold out run heater and fan inside car and out


Are you loosing radiator fluid. sometimes the heater core will rupture and you will smell burn odor. also check for strange rubbing sounds or screeching coming from the blower fan motor. or engine exhaust manifolds are hot when car is on, make sure nothing is leaning on them which will cause a burn odor. Any odor coming from outside will find it's way inside through the fresh air vents.

Burning smell inside car. Not under hood. What could it be?


I had the same problem with my 2005 Honda Accord. I would happen only sometime but is a distant odor I smell from inside the cabin. Older Hondas sometimes have gasket problems that leak small amounts of oil onto the exhaust manifold. Ask the mechanic to go check the valve cover gaskets. They replaced a new gasket to my car at the Honda dealer and I haven't smelled that burning odor since then. Good luck.

Did u notice the smell right after oil change ?I so they might have spilled some on the exhaust manifold or on the motor itself ... If this is a strong odor return to where the oil was changed and ask them to double check everything they didif it wasnt them maybe they can find out what is indeed making the smell.. good luck hope this helps

Accidentially left the the engine oil cap off. Drove for less than 24 hours about 20 miles. The car had a rubbery odor. I thought it was the tires from my daughters bike in the back. The engine oil...


If the cap has been replaced, wait til the car is cool/cold and purchase a can of brake parts cleaner and inspect under the hood for signs of where the oil sprayed. Clean it with cleaner and allow to dry prior to starting it.....fire hazard. Good news, this stuff dries fast.

I drive 3181 N42 02 Reg. I'v been told the car has oil leak, jus yesterday whilst driving I could smell something like burning metal and a particular noise I don't know where it is coming from. Please...


Let an auto tech look at it because one way or the other it's going to end up on some tech's hands. Burning oil smell must be from the valve cover leak and dripping on top of the hot exhaust manifold burning it. The only time I smelled burning metal odor was from a smelting plant. It had an acidic smell that going to put you in tears.

I changed my oil and now my car is smoking ad it smells like something is burning


You don't say where the smoke is coming from, but if it's from under the hood you may have spilled some oil on your exhaust manifold when you were refilling the engine. If so and there isn't too much oil on the manifold it will soon burn away. If you look and see a puddle laying in a pocket somewhere along the manifold you can wait until the car cools and wipe the puddle up with paper towels and clean it as best as you can with soap and water. Then rinse it off with a hose. If you find this is the problem be sure and let the car cool down if it's hot because cold water could possibly break the manifold. If it's just warm you'll probably be safe to clean it.

What is the smell and does it have to be fixed?


A burning rubber smell under the hood might be just that - consider having your accessory drive belt inspected, as it is possible that a bearing in one of the accessories (alternator, power steering pump, air conditioning compressor, etc.) or in the tensioner mechanism might be failing. This sort of fault will often cause that particular accessory bearing to spin less freely than the others, and as a result the belt continues to pass over the associated pulley at the same speed as the engine. Essentially, the result is similar to a car spinning its tires on dry pavement - and a similar 'burning rubber' odor is the friction and heat of the rubberized belt.

If the odor is more like burning oil than burning rubber, the rear valve cover gasket is situated in a place that results in dripping oil, even small and unnoticable amounts, onto the exhaust manifold that is directly underneath the valve cover.

These two items might be places to start your inquiry. Best of luck to you!

White smoke and smell of eggs


White smoke in the exhaust, more so on a cold start. That's steam. Water is getting into the combustion chamber. Most likely coolant.
Put your hand in the white smoke to capture the odor. (don't burn yourself)
What does your hand smell like? Coolant (anti-freeze & water) smells sweet.
Likeliest cause = head gasket. Possible = cracked head - depending on how hot it got. Less likely = cracked intake manifold.
Maybe a blown head gasket

I can tell about a couple of odors from oils that are quite indicative of the places where they oil is leaking into the exhaust though.

You've got a few internal places where oil can get into the engine and even some can get into the combustion chambers. They have distinctive odors and can really help diagnose the cause or reason for the oil consumption.

First let's start with the "sweet-smells".

This means that the oil have gone through the combustion process along with the engine's fuel (gasoline or diesels too!). It is about the same smell you get whiffing the exhaust on a 2-cycle engine with gas-oil premix.

Places where this CAN happen:

1) Cylinder walls ie; piston rings, worn or broken.
2) PCV system where the oil is sucked into the manifold under vacuum and is entrained into the combustion chamber in the normal air-flow to the engine for combustion.
3) Intake runner-to-head surface gasket(s) where the intake can actually **** oil from the cam tray area or the inner valley between the heads and the intake manifold.
4) Occasionally from changing spark plugs in "well" type plug chambers that let the plug get very close to the head through the head casting. Taking a plug out and letting the collected oil fall into the cylinder is usually a temporary situation, but can scare you when it happens.
5) Cracked head or blown head gasket: this usually has to happen where the head has a high pressure passageway for the oil to travel through the head to get to a cam tower on top of the head.
6) Now - here's something that's gonna get debated, fer sure! ONLY the intake valves can leak past their stem seals and allow oil to travel down the stem onto the combustion process. Remember that I am speaking or "sweet" oil smell here.


Now some of the "not sweet" or bitter oil smell:

1) Exhaust guides or stem seals on the EXHAUST valves ONLY can cause a very acrid smell of nasty, eye watering and cough-inducing stink.
2) CVCC or pre-combustion chambers can also cause this problem. The Honda CVCC engines were notorious for this! The auxiliary valve can leak oil into the pre-chamber and then it opens the valve and dumps the burning mess into the main cylinder head area and the results are a bad BAD stink and lots of white/blue smoke.
3) RARELY...very rarely the exhaust port AFTER the exhaust valve seat can become perforated and allow oil to get into the exhaust stream. It does NOT burn here - rather it just cooks-off with a very bad smell.

So-o-o-o

Acrid oil smell
- the oil has NOT gone through the combustion process in the cylinder head but is rather "cooked" into a stinky odor. It may or may not smoke too much too.

Sweet oil-burning smell - oil that has been burned as part of the combustion process in the combustion chamber on one or more or even all cylinders.
