1 Engine Builder Team Contest This is a team contest to give students the opportunity to develop and show their talents of teamwork and engine building skills. Scope of Contest A team of five students will compete in a written contest at the region level. Each team member will take an exam consisting of 30 multiple choice ASE/NATEF type questions on Engine Repair and Diagnosis. The team member scores will then be averaged to determine the overall team score. The team with the highest average will represent that region at the state hands-on contest. The state contest will put eight teams (one team from each region) in a head-to-head engine builder shootout. Students will disassemble and reassemble a 350 Chevrolet engine. The teams will be judged on sportsmanship, quality of work, use of safe work practices, professionalism, as well as the finished product. Clothing Requirements: Region contest: Students will dress in an appropriate manner to stay within the spirit of the event. Students should be neatly dressed, with shirt tucked in and pants at the waist. Hats will not be allowed. State contest: Khaki type pant (no jeans), pullover solid color collared shirt (team should all be the same color); black or brown leather work shoes, and safety glasses with side shields or goggles. (Prescription glasses can be used only if they are equipped with side shields. If not, they must be covered with goggles.) Baseball style hats will be allowed at this event, but must be worn with bill facing the direction of travel. No hats will be worn backwards. Work

2 shoes/boots meeting ANSI Specifications or rubber soled, oil resistant shoes. Eligibility: Open to active SkillsUSA GA members enrolled in a CTAE Transportation Logistical Support program with entry-level skills for the occupational objective. Team members can be from different schools as long as they are served by the same automotive program. (Example: Students from South Effingham High School and Effingham County High School that attend Effingham College and Career Academy would be eligible to compete as a team.) Teams cannot be built from students that attend high schools that are served by different instructors. (Example: Peach County High School, Dodge County High School, and Hutchings Career Center cannot build a team. Each school has its own instructor; therefore each school would have a team.) Safety Requirement: Both the instructor and the contestant certify by agreeing to enter this contest that the contestant has received instruction and has satisfactorily passed an examination on the safe use of all tools. Further they agree that Skills USA, the Skills USA Championships Technical Committee and judges are released from all responsibility relating to personal injuries resulting from their use. Contestants will be removed from competition if proper training has not been provided and/or they are using the equipment in an unsafe manner.

3 Equipment and Materials: Supplied by host school: 1. All necessary service publications for the contestants (this will be sent prior to the contest to the host school) 2. All necessary information and furnishings for judges and technical committee (this will be sent to the host school) Supplied by Contestant: Safety glasses All necessary tools and equipment for the contest. No power tools will be used! Skill/Test Region Contest: The region contest will consist of a 5 member team. Each team member will take an exam consisting of 30 multiple choice ASE/NATEF type questions. Each individual exam will be scored and then averaged for the overall team score. The team with the highest average will then represent their region at the state hand-on engine builder contest. If the first place team is unable to represent that region then the second place team will be the representative. The members taking the exam must be the same students that compete in the hands on contest. State Contest: General Rules for Disassembly/Reassembly

4 The state contest will consist of a 5 member team from each region for a total of eight teams. There will be 4 team members allowed to work as assemblers of the engine with one member of the team who must remain behind the table to act as a support person to keep parts, tools, and specification sheets in order. This is a timed event which the best score after penalties will deem the winner. Students will start with a Lemans style start from the back of the parts/tools table and enter assembly/disassembly area from the left end. At this point students will begin to disassemble their engine. All parts, with the exception of the crankshaft, must be removed and placed on the parts table before reassembly. These are the parts that must be removed from assembly: Carburetor Intake Spark plugs Headers Cylinder heads (valves/valve springs do not have to be removed) Valve train (pushrods, lifters, etc ) Camshaft, timing chain and cam sprocket Oil pump Pistons and connecting rods (rings do not have to be removed from pistons) Distributor and wires All tin (oil pan, timing cover, valve covers, air cleaner) Harmonic balancer

5 All members should them move to the back of the parts table around the left end for the judge to check assembly to determine if disassembly is complete. Once checked the team should proceed with reassembly. All parts must be reinstalled in proper manner and in the correct location (Example: number eight piston should be in number eight hole). All fasteners must be torqued to manufactures specifications. Torque wrench must be set by team member and checked by the judge prior to torqueing the fasteners. Correct torque sequence must be followed or a time penalty will be added to the final score. Penalties will also be added for improper torqued fasteners. Valve Adjustment Before the engine is completely assembled, the valve train must be properly adjusted. The following components and any other components that must precede them in reassembly should be installed before beginning the valve adjustment. Cylinder heads, valve train, timing chain, damper, and damper turning tool should be installed. Valves can only be properly adjusted when the lifter is resting on the camshafts base circle. Improper valve adjustment will result from adjusting the valve while the lifter is on the camshaft lobe or lobe ramp. Use the following guide to insure the lifter is resting on the camshafts base circle before valve adjustment. With the #1 piston at TDC (top dead center) on the compression stroke you may adjust the following valves: Intake Valves- #1, #2, #5, #7

6 Exhaust Valves- #1, #3, #4, #8 Now rotate the engine clockwise 360 degrees. The #1 piston should again be at TDC, only this time it s the exhaust stroke. Coincidently the #6 piston is now at TDC on the compression stroke. You may adjust the following valves: Intake Valves- #3, #4, #6, #8 Exhaust Valves- #2, #5, #6, #7 Use the following procedure to adjust the valve. You will start with the rocker arm nut loose. Slowly tighten the rocker arm nut with one hand while rotating the pushrod back and forth with your other thumb and index finger until you feel a slight drag. At this point there should be no valve lash (extra clearance). Now turn the rocker arm nut an additional 3/4 turn. Now the valve is properly adjusted. Disassembly 1) All components to be placed on table, no engine components on floor (subject to venue). Tools can be placed on floor while in use, but cannot remain there during competition. 2) Torque wrenches cannot be placed on floor at any time during the event, but can be held by a team member or placed in /on a padded tray or returned to the work bench.

7 3) Rotating torque will be determined by judge at the beginning of disassembly. (Reassembly torque must be within 25 % of original spec.) 4) Air cleaner - must be removed from carburetor separately. 5) Distributor and spark plug wires can be taken off as an assembly. 6) Headers and gaskets (headers must be removed as separate procedure before head comes off).
