hich of the following operations is NOT required when replacing a cylinder head gasket?

Checking for warpage.
Checking for squareness.
Checking for leakage.
Cleaning the bolt holes.

Low and steady vacuum gauge readings can be caused by.

Worn valve guides.
Piston ring leakage.
An incorrect fuel mixture.
An exhaust restriction.

A cylinder compression test will detect all of the following problems EXCEPT.

Valve not seating.
Worn valve guide.
Broken piston rings.
Leaking head gasket.

After a valve job, the spring assembled height is too great. It can be corrected by.

Grinding the seat.
Installing new springs.
Installing shims.
Tipping the valve.

Which of the following is NOT one of the starting system circuits?

Control circuit.
Isolated circuit.
Insulated circuit.
Ground circuit.

After machining, the cylinder walls are cleaned with:

Solvent
Soap and Water
A hot tank
A glaze breaker.

If the block and rods are in good shape, main and rod bearing insert wear will be.

Even across the bearing face.
Concentrated on apparently random areas of the bearing faces.
In a short arc near the fillet.
Greatest in the center and minimal at the parting line.

A V-type drive belt that rides too low and bottoms in the pulley groove causes

Premature wear, glazing, and slippage.
The belt sides to wear excessively and split.
High belt tension that can lead to bearing damage.
The belt to bind, seize, and eventually break.

Which of the following items must be removed in order to remove hydraulic lifters from an OHV engine?

The camshaft.
The rocker arm.
The pushrod.
The cylinder head.

Which of the following does NOT indicate a bent connecting rod?

Uneven side clearance on the piston skirt.
Wear along one edge of the bearing shells.
Wear at opposite ends and sides of the bearing shells.
A diagonal pattern on the thrust face of the piston.

Most turbocharger failures are caused by.

Excessive high-speed operation.
Exhaust temperatures too high.
Dirt and contamination.
Operation with leaded gasoline.

In a cylinder compression test, if the compression is low on the first stroke and increases on following strokes but never reaches specifications, it probably means:

Cylinder compression is okay.
Rings may be worn or valves may be sticking.
Head gasket may be leaking.
Excessive carbon build-up.

Connecting rods are marked.

After removal.
With a scribe.
Before removal.
On the bottom of the cap.

The most common valve seat angles are.

30º or 45º
15º or 30º
30º or 60º
45º or 60º

Checking manifold vacuum with a gauge will reveal all of the following problems EXCEPT.

Worn valve guides.
Exhaust restriction.
Worn piston rings.
Sticking hydraulic lifter.

A thermometer, timing light, and tachometer can be used to check the operation of.

The cooling system.
The thermostat.
An electric fan.
A fan clutch.

The rated temperature of a thermostat indicates.

The temperature where it begins to open.
The temperature where it is fully open.
The temperature where it fully closes.
The thermostat bypass temperature.

High compression readings, good cylinder leakage test results, and good power balance can be the result of.

Incorrect valve timing.
Exhaust restriction.
Carbon deposits on the pistons.
Leaking valve guide seals.

When tested for one minute at 500 rpm, most mechanical fuel pumps deliver.

1 quart of fuel.
1 pint of fuel.
1 gallon of fuel.
1 cup of fuel.

When installing an oil pump, it should be primed with:

Assembly lube.
Petroleum jelly.
Motor oil.
High-pressure lubricant.

Valve springs are bench tested for all of the following EXCEPT.

Installed height.
Free height.
Tension pressure.
Squareness.

On a conventional distributor, the air gap between the trigger wheel and the pickup coil can change because of.

Incorrect base timing setting.
Incorrect timing advance.
Worn distributor bushings.
Worn distributor cap and rotor.

Of the following types of sealant, which would be used when replacing a valve cover with a formed-in-place gasket?

High tack.
Anaerobic.
Aerobic.
Metabolic.

The preferred rate for charging an automotive battery is.

Less than 5 amps.
5 to 15 amps.
15 to 25 amps.
More than 25 amps.

Install rods and pistons.

By tapping with a ball peen hammer.
By pushing gently with a wooden hammer handle.
Clean and dry.
With rod caps reversed.
