Because exhaust is an important part of your cars performance, repairs to an exhaust system can be very expensive, costing hundreds or even thousands to replace. This cost is largely made up of parts and labor changes from your garage. The good news is, with a little safety, know-how and some tools, you can purchase the parts yourself and save hundreds over the price of a costly in-shop repair.
You should replace your oil filter every other time you change the oil. Some mechanics suggest doing so that often is unnecessary, but it’s a small investment to protect your engine.
When your car is on, many of the parts become extremely hot. If you’re not wary, you can suffer bad burns. It’s worth noting that high temperatures are not limited to your engine and transmission. Your recycle catalytic converters, radiator, and various pipes all need to cool down before you put on your weekend mechanic’s hat.
Vehicle exhaust systems carry away the gases that are created when the fuel and air are burned in the combustion chamber. These gases are harmful to humans and our environment thus the laws regarding emissions in highly populated areas. In larger cities all the traffic means a higher concentration catalytic converter recycling of these harmful gases are released into the air every single day. It is in the best interest of everyone living and working in these areas to have every vehicle be performing at peak levels without having a high emission rating. That might be why in many larger cities we don’t see very many really old worn out vehicles, they can’t pass an emissions test.
The answer is to control your fuel ratio, you can do this several ways. The one I recommend is to use an EFIE (electronic fuel injection enhancer) the name is a bit of a misnomer, because it works on non fuel injection engines too. Basically an EFIE will control the voltage relayed from your o2 sensors. Depending on the quality of the EFIE you can get this control down to the millivolt. This allows you to lean back your fuel as you introduce more HHO, meaning your using less gas and supplementing it with HHO, which is made from water. How cool is that? HHO has three times the potency of premium gasoline, so you’ll have no problem supplementing a decent amount of fuel. This is how you can maximize your miles per gallon. The side benefits are just a bonus.
My current car has a rattle on the catalytic converter. When I drive or rev my engine, you can hear a tinny clicking sound. This sounds terrible, and people probably think that my car is falling apart (I’m not saying it isn’t) but the rattling sound is only the “Cover” of the cat\. For the longest time I consulted with my uncles who are both mechanics and asked them if I was in need of a new catalytic converter. Luckily they both assured me that the cover was causing the sound and can be replaced of fixed just by tightening. So as a wise piece of advice, if you hear a rattling, and it sounds like your cat\r, 99% of the time it is just the cover and you can get that easily fixed or replaced very cheaply.
So, that’s the underneath check list for your new used car. After this, everywhere else to check is fairly easy to get to. Good luck in your search for a good used car. I hope these tips have been or will be helpful.
