Tech Tip #6

The three major contributors to engine failure are dirt, detonation and water. We can control detonation with race fuel and we can keep water out by replacing O-rings on exhaust and making sure none enters when pressure washing. Dirt is up to you! We have told you this before in previous tech tips. Dirt is the most common cause of engine failure. Since dirt can only enter through the air filter or the air boot, it is up to you to maintain these areas. The picture below illustrates catastrophic failure due to dirt.
