HOW TO PREVENT ENGINE FAILURE!
WHY ENGINES FAIL BEST WAYS TO PREVENT FAILURE
Bearing failure due to improper pre-lubrication.
Follow pre-lubrication procedure to ensure engine is primed and
ready to fire. See Step 2 on Page 4.
Improper tune, or no tune.
It’s extremely important to note that LS engines require professional level
tuning. Engines shipped without an ECU require professional level re-tuning
of your factory ECU. Engines shipped with an ECU will still require professional
chassis dyno level fine tuning for optimal performance.
Overheating. Always install a new thermostat with a bypass hole for your engine.
Leaking gaskets due to inadequate torque, or loosening
during heat cycles.
Always retorque manifold bolts after a heat cycle to ensure proper seal. If
using aftermarket headers, contact the manufacturer for proper gaskets.
Recheck intake, front accessory, and water pump bolts to ensure nothing has
loosened from heat cycling.
Poorly cleaned add-on parts that result in premature
failure.
Clean all add-on parts professionally to prevent abrasives from getting in oil.
Never use abrasive sanding discs or blasting media to clean parts.
LS Engine Installation
The following information should be read, and understood, if you’re replacing an existing LS engine, or your vehicle came equipped
with a factory LS engine. Although all LS engines are similar, please be aware that BluePrint Engines manufactures engines with
both 58X and 24X configured reluctor wheels. You can install a 58X engine into a vehicle originally equipped with a 24X engine with
some accommodations, but you cannot install a 24X into a 58X vehicle.
You will also have to note and research the following:
n LS front accessory drive spacing variations
• Corvette (most BPE engines)
• F body truck
• Truck
• Late Camaro
n General gen III vs. gen IV LS engine series
n 24X vs. 58X Reluctor wheels
n Possible 58X to 24X signal converter
n Cam sensor location, and window
n Throttle body differences and adapters
n General sensor locations
• Knock
• Cam
• Oil pressure
n Differences in intake manifold styles and positions
• Car configuration
• Truck configuration
• Cathedral vs. L92
n ANY of our BluePrint Engines LS engines going into
ANY GM vehicle that originally came with an LS may require:
• VVT and DOD consideration and deletion
(BluePrint Engines do NOT have VVT, or DOD)
• Professional level tuning
• Wiring extensions / splicing
n ANY of our BluePrint LS Engines going into ANY GM vehicle
that originally came with an LS will require:
• Sensor wire lengthening and position changes
• Pinout changes on throttle body
• Intake manifold change or purchase
You may also require:
n Reluctor signal converter throttle body or throttle body
adapter
