Understanding Pre-purchase Mechanical Inspection

The point of the pre-purchase inspection is to confirm you’re not getting a dud. It’s to confirm the car is going to run, today and into the future. Your inspector will investigate the engine, radiator, battery, exhaust, tyres and body. They’ll check for oil and coolant leaks, battery issues and poorly done modifications. You need an expert eye on this because even the shiniest car can come with hidden problems under the hood, and usually, they’re expensive to fix. Here’s what you should run your eye over before you test-drive a car. This is not a substitute a professional mechanical inspection and you should always seek expert advice. Think of this list as early warning signs - a red flag. If any of these issues present themselves, skip the professional inspection and move on to the next car.

Oil indicators

Oil can tell you a lot about the engine, so check it. If you pull the dipstick out and the oil residue doesn’t reach the ‘full’ marker, or it looks thick and black, this is a sign that the car has not been maintained well. If you look under the oil cap and find gritty carbon deposits there too, you can be sure there has been some engine neglect.

Leaks

Look underneath the car. Look at the radiator. Look at the hoses. Are there any signs of leakage? Cracking? Corrosion? If the answer is yes, there’s a good chance you’ll run into some of those hidden problems we mentioned about.

Filters

Look for excess dust, filter condition and clean and or replace filters as necessary. Check airbox seal is intact and closes correctly and all airbox latches and mounting point. Check all intercooler piping for damage & hose clamps. Do a visual check of primary and secondary fuel filters, if the secondary fuel filter isn’t fitted, recommend getting fitted pre-trip.

Windows

Check windshield and all windows and exterior light lenses, both in terms of cleanliness and visibility. Check windshield wipers and washers are operational.

Smoke from the exhaust

Turn the car on. Have someone rev it a few times. Is there smoke from the exhaust? Can you smell anything in the smoke? Either would be bad. Usually, a smoky exhaust indicates an oil-burning engine, which tells you there is a problem to be found.
