How to Fix Rust on a Car

Rust often gets its start from a rock chip or door ding. It can also be caused by snow, water, salt or a combination getting in behind the metal. In the latter case, you may not see any indication of rust until it bubbles the paint or leaves a hole in the metal. While you may chip off the bubbled paint and find fairly solid metal underneath — in which case you can try some of the suggestions below — holes or “squishy” metal indicate a larger job that’s beyond the scope of this article (and possibly your time, skill and budget). About the best you can easily do in this case is apply some rust converter to slow the spread of rust, which is covered below. But first, it’s important to take some safety precautions when performing any of the following tasks. That includes wearing safety glass...

How to Safely Wash a Car Engine

If you've ever taken your car in to get it detailed, you know that one of the finest feelings is popping open the hood and seeing the engine shining like it just came off the lot. You may have thought about trying to get the engine that clean on your own, but is it safe? As long as you take precautions to protect your engine, especially the electrical components, you can safely wash your engine bay at home. However, if you feel uncomfortable dealing with your engine's components while preparing them for the wash, consider taking it to the shop instead and let the pros do it.

Cleaning an Engine, Are There Any Mechanical Benefits?

Though it is true that while oily, greasy dirt that accumulates on an engine can trap some heat, it’s doubtful it would be enough to cause an engine to overheat or even run hotter than normal. If a car engine overheats, the probable cause is more likely in the cooling system — or because the car is towing or carrying too much weight, or some other issue unrelated to the cleanliness of the engine bay. There is no evidence to suggest that a cleaner engine runs better than one that is dirty. It is unlikely that something as simple as a little decreaser or cleaning spray could make a vehicle run better. A Cleaner Engine Does Offer Some Benefits However, cleaning your car engine does offer certain benefits. First, doing so helps determine where oil or grease is coming from — such as a lea...

What are the signs that a car needs a valve adjustment?

Few automotive engines today require valve adjustments, as the valve trains are “zero lash", controlled by hydraulic tappets or lifters. Any valve noise is generally a result from a lifter with internals fouled by dirt or other contaminants. Yet another reason to keep that oil changed! Older engines have solid tappets, and the valve train is generally adjusted at the rocker arm. Cold clearances can be from about .006″ to .020″, depending on the engine, and depending on whether it is the intake or exhaust valve (exhaust valve clearance is generally larger). These clearances will approach zero lash when the engine is at operating temperature due mainly by the lengthening of the valve stem and pushrod by heat expansion. Too loose a valve adjustment will cause noise and undue wear, whereas ...

What Different Colours of Exhaust Smoke Could Mean – TROUBLESHOOTING

Most of the time, your car’s exhaust should barely even be noticeable, quietly pumping out spent gasses from the combustion process at the back end of your vehicle. But if a problem were to arise, then blue, white or black smoke could start to appear from the exhaust pipe. This unusual exhaust smoke could be coming out of your exhaust when the car is stationary or accelerating, and it may well cause an immediate sense of dread that an expensive repair bill is on the horizon. While exhaust smoke from petrol or diesel cars could indeed be a sign of a serious mechanical issue, however, this is not always the case. So what exactly does a smoking exhaust mean? There are a number of potential causes of pollutants coming from your car's rear end, and our handy guide is here to help you f...

Small Engine Carburetor: Want to Learn How To Troubleshoot? Read…

Small engine carburetors don’t handle bad or dirty gas very well; if you own a small engine, you’ll encounter carburetor problems at some point. In this guide, I’ll cover the main problems with small engine carburetors and the solutions. So how do you troubleshoot a small engine carburetor? The most common issue with all small engine carburetors is gumming (old gas); cleaning the carb usually solves the problem. Typical carburetor-related problems include: Tank – Outlet hole inside the tank blocks with grit stopping or slowing fuel flowing to the carburetor Cap – Cap hole allows the tank to breathe; when the cap vent fails, it seals the tank making fuel flow to stop Fuel Lines –Fuel lines Leak at connection points and on occasion can block, thereby stopp...
