Timing Belt Basics – Avoid the Unexpected Cost of Engine Damage

10/14/2025

A timing belt is one of those things that’s critical to replace; according to the auto manufacturer’s schedule. Timing belt replacement is most often between every 75,000 and 100,000 miles. So, check your owner’s manual […]

Fuel Pressure Regulators – Commonly Fail In One Of Two Ways

10/07/2025

All fuel-injected engines, have fuel pressure regulators to maintain a regulated high-pressure level. Fuel pressure regulators, must keep the pressure constant, in order for all the components of the system to work properly. Consequently, if […]

Catalytic Converter – Failure Signs And Testing – Learn The Basics

10/03/2025

So, a catalytic converter, is a device used to reduce the emissions, from an internal combustion engine. Consequently, the catalytic converter works, by breaking down unburned gases, left over by the combustion process. And, requires […]

Pushrods On G.M. 3.1-3.4 Engines – This Is Where Length Matters

09/26/2025

Exhaust and Intake Pushrods, on G.M. 3.1 and 3.4 engines are different lengths. So, quite often we still see bent push rods and valves, when they are mixed up. Consequently, Exhaust pushrods on G.M. 3.1 […]

Engine Oil Pressure Warning – Possible Causes And Testing

09/22/2025

Suddenly, an engine oil pressure warning light or a low oil pressure reading, appears on your dash. At that point, the engine oil pressure warning, is the only thing you should be thinking about. Above […]

Crankshaft Thrust Bearing Failure – Causes And Remedies

09/16/2025

For years, both transmission and engine rebuilders, have struggled at times, to determine the cause, of crankshaft thrust bearing failure. Diagnosing a crankshaft thrust bearing failure, can sometimes be simple, but often is tricky. And, […]

Variable Valve Timing (VVT) – Function And Its Advantages

09/12/2025

So, variable valve timing (VVT) adjusts the opening times and lift of the valves, to suit all operating conditions. This ensures ideal charge cycles, within a wide range of engine speeds and loads. Fuel consumption […]

Air Injection System (AIS) – Air Pump – Function, Types, Failure

09/08/2025

The air injection system (AIS), is actually part of the car’s exhaust system. Since no internal combustion engine is 100% efficient, there will always be some unburned fuel in the exhaust. As a result, the […]

Throttle Position Sensor (TPS) – Function – Failure – Testing

09/03/2025

So, the throttle position sensors function (TPS), is to supply vital information to the vehicles engine control unit (ECU). And, this information is based on, the actual position of the engines throttle valve. So, your […]

Engine Rebuild Reasons – Low Compression And Oil Consumption

08/29/2025

So, the most common reasons to do a engine rebuild are, loss of compression and or excessive engine oil consumption. Consequently, what’s important now, is to recognize the signs of trouble, before you end up […]

Engine Stalling – Proper Troubleshooting And Maintenance

08/25/2025

Engine stalling problems, can be hard to find and are often, sensor or temperature related. And, are more likely to occur, during cold weather or when starting a cold engine. So, this kind of engine […]
