When your car’s engine suddenly turns up smoke, you need not to panic; and knowing why this happens will help you stay calm.
Smokes in the engine occur because it may be worn. There is a possibility for a worn engine to smoke due to oil leaks into the cylinders around worn valve guides, or worn oil rings, or both. Under these circumstances, white smoke will be produced. This is process is oil burning. This is differentiated from fuel burning, wherein a rich fuel problem creates black smoke.
When you start the engine after it had been resting for hours and you drag white smoke, the problem could be worn valve guides. While the car is at rest, oil that lies on the cylinder leads the leaks into the cylinders. Since the engine is at rest, the oil sufficiently gathers that causes a momentarily smoke once the engine is started.
There is no need to rush or to be hysterical as long as the smoking engine does not affect spark plugs too often and can still pass emission tests. The only bad news is that you cannot use your car for a while to ensure safety. Under this circumstance, it is best to bring your car to a mechanic to immediately resolve the problem.
Sometimes, the problem could be other parts like the muffler. Ask a mechanic to know if your Dynomax muffler already needs a replacement.
When you are on the road and your car suddenly begins to belch out white smoke and something broke, immediately park it and start scheduling a rebuild or a replacement for your engine.
A white smoke coming from your engine implies a tired engine. It therefore needs a complete rebuilding. Unless you can do the rebuilding by yourself through your owner’s manual as a guide, take your car engine to a reliable auto repair shop. Let the cylinders, block deck cylinder head(s), rods, engine heads, and crankshaft be repaired. Buy a master engine kit that contains piston rings, main, rod and camshaft bearing, a new camshaft (stock) and lifters, timing gears and timing chain, oil pump of normal volume, freeze plugs, gaskets and seals. It is also best to have a new water pump.
Keep this in mind: Never ever attempt to rebuild the engine by yourself without properly understanding what are written in the manual and well functioning accurate tools. And if you are doing it for the first time, be sure to have the assistance of someone who has the knowledge on this matter.
Make sure to always rebuild your engine as it was originally built to avoid future damages, minimize cost and effort and to assure longer engine life.
Exact factory replacement engines are available for some cars. And you will be surprised because they are sold under a just enough price. These are known as factory crate engines. These are top of the line brand new engines that are made by the car manufacturers and have a fair warranty. Your car dealer can give you the options. Then canvas the price among dealers and suppliers to find the quality yet affordable one.
Remember not to do a rebuild by yourself when you are not prepared. For sure, you just cannot do the right job and you will probably end up having an injury. A good rebuild needs a quality engine lift and then followed by pulling the engine. You are assured of less hassle in the future when you are able to do the right rebuild.
If your car is high mileage, say over 100K miles, you may pull the engine and transmission together. After doing such, you can rebuild them both at once.
