ENGINE INSTALLATION AND TUNING TIPS:
Performance engine durability is dependent on several supporting systems including the cooling system, fuel
delivery system, ignition system, and oiling system. If the support systems are not adequate, poor engine
performance and possible engine failure could result.
OILING SYSTEM CONSIDERATIONS/COMMON PROBLEMS
Priming the oiling system before starting a new engine is crucial to engine life. This is important on initial start-up of
a new engine and if a used engine has not been run for extended periods of time.
Does the oil pan have adequate capacity? Most performance vehicles require a 7-qt minimum capacity. All engines
will benefit from increased oil pan capacity.
Does the oil pan have proper oil control baffling for the vehicle’s braking, acceleration, and cornering capabilities?
Road Race cars need oil control in four directions: braking, acceleration, LH cornering and RH cornering. Drag race
cars need oil control in two directions, braking and acceleration. Baffles must be designed to keep oil over the
pickup screen at all times.
Is the pickup screen the proper distance from the bottom of the oil pan? If the oil pickup screen is too close to the
bottom of the oil pan, it can cause cavitation. If it is too far away, it will cause the pump to draw air and minimize
lubrication capacity. The pickup screen should be located .250" to .375" from the bottom of the pan.
Does the design of the screen on the pickup tube create restrictions? We have seen some pickup tube screen
designs that restrict oil flow as much as 75%. Wire mesh is good. Perforated metal is usually restrictive. Measure
the wire size and calculate the flow area. Most aftermarket screens have less flow area than stock screens.
If using a remote oil filter mount or oil cooler, make sure that all of the components are large enough to eliminate
any restrictions to oil flow. Many Cobra replica kit cars use components that are too restrictive.
•
Undersized oil lines commonly restrict oil flow.
•
The more bends/turns in an oiling system, the more restrictions that are created.
•
Poorly designed remote filter mounts and adapters can create restrictions.
•
Be sure that the oil cooler flows enough oil to meet the engine's requirements.
•
Never reuse a used oil cooler. Debris gets trapped and cannot be cleaned out.
•
Poorly designed oil filters can cause a restriction.
•
Many oil systems only flow one way. Connecting the remote oil filter or oil cooler lines backwards can cause
engine damage/failure.
