Course Length:
  • 16 Week


This will be exciting hands on class. You will learn how to use hand tools and diagnostic tools. We start with a 305 small block. The first thing that is done is I run the motor with an open exhaust so you can get the full effect of horsepower you know the engine ran. You will also get a good taste of the industry. It has been my life. I received my training at Pierce College earned my degree with an emphasis in automotive technology. I started in the industry as a mechanic for Mazda working on rotary engines.

Then I worked for the City of LA Department of Water and power as an equipment mechanic. I will talk how wonderful that was. I went to Cal State LA and earned my engineering degree and moved up at Water and Power to an Associate safety engineer. I will discuss career opportunities with you for that. While at the Dept. I started an Independent Automotive repair shop. Gary’s Automotive in Northridge, than opened a body shop and developed a professional Boat racing team. Automotive has been wonderful for me and it could be for you also. I want to be your coach!

Course Description

As I mentioned I run the engine for you. You will start the diagnostic process using a compression gauge and a leak down gauge. You will come up with a set of numbers and I will teach you how to use then in the evaluation of the overhaul and repairs. Next you will start the tear down and inspection process. You will remove the intake manifold, cylinder heads. Remove the oil pan, timing cover, crank shaft and cam shave.

You will need down and inspect the cylinder heads and lap the valves along with measuring the valve spring tension.

Than we go through the inspection process see what can be re-used and what needs to be replaced.

Than the measuring process. That is what makes an engine live. You will have command of measuring all the parts in the engine.

Now the engine has to be re-assembled and ran. Don’t worry I will give you allot of help getting it back together.

You will remember when your engine runs for the rest of your life. I remember mine running at Pierce College and that was a long time ago.

What to Expect in this Course

You will have a thorough understanding how a 4 stroke gas piston engine operates. You will also understand the industry if it’s something you would like to enter and make a good living or be a wise consumer.

Types of Assessments

The main assessment it the tear down, inspection and re-assembly of your engine. I often have extra credit like the dream machine project. That is anything that rolls, floats or flies that you are interested in. It is a presentation lot of fun.
