PRE-LUBRICATION
GETTING READY FOR YOUR ENGINE INSTALL
22
IMPORTANT: Engines are shipped without oil and need
to be primed before first fire up. We did prime this before
running on the dyno, but for warranty purposes, engine
needs to be primed using the following instructions.
LS engines require pressure priming to prelube the
engine. Failure to follow these steps can result in dry
fire, bearing failure, and will void the warranty.
Make sure the engine is level and the appropriate filter and
amount of oil are used.
a. Oil filter recommended:
BluePrint Engines (Part# BPPB160)
www.blueprintengines.com/products/gm-gen-iv-ls-oil-filter
b. Oil filter alternatives:
Wix 57060, NAPA 7060, K&N HP1017, Baldwin B160,
or AC Delco PF48E.
c. Oil requirements:
Break-in oil in not required. However non-catalytic
converter equipped vehicles can run BPP710 Break-In Oil
for the first 500 miles to promote ring sealing, rocker arm
wear-in, etc. BPP10W30 conventional oil can be used for
normal operation. A standard, non-synthetic 10W30
may also be used.
Fill oil filter with correct break-in oil or conventional 10W30
oil. Reinstall and tighten oil filter.
DO NOT USE SYNTHETIC OIL FOR THE FIRST 500 MILES.
Synthetic oil can lead to cross hatch being removed from
cylinder walls, leaks, and other issues. Use STANDARD oil,
or break-in oil, for the first 500 miles.
Fill engine crankcase with the appropriate amount of oil
for your application.
Locate and remove the front, left oil galley plug from the
engine block. (Fig. 1) *PSLS3760CTF used for reference.
Insert 1.5" of a 2' long, 3/8" I.D. fuel hose into the block
where you removed the plug.
Attach a funnel to the other end of the hose and fill with at
least 8-10oz of oil slowly, allowing oil to fill the oil pump.
Leave hose attached for at least 3 minutes until all oil has
filled the pump gears. (See Fig. 2 above for reference)
Crank engine over without ignition or fuel enabled and verify
oil pressure out the port in the top rear of the intake. If you
don’t have oil pressure, stop and call BluePrint with the serial
number.

Your engine has been assembled with select parts based on the engine configuration you ordered. Prior to installation, check
to be sure your engine arrived with the parts you ordered (base, base dressed, or fully dressed). Now determine the add-on
parts you need to complete your installation.
Add-on parts recommendations and specifications for your engine are available at www.BluePrintEngines.com on your
engine's product page. Depending on the engine you ordered, add-on recommendations and related specifications may
include the harmonic balancer, flexplate/flywheel, spark plugs, spark plug gap, water pump, etc.
Certain items like water pump, harmonic balancer, flexplates/flywheels, are much more easily installed prior to the engine
being lowered into the vehicle.
Certain components, like crank pulleys, may be best installed after the engine is lowered into the vehicle for firewall or
frame clearance.
CAUTION: Your engine’s assembly lube was washed away during dyno testing. Be sure to PRELUBE YOUR ENGINE
before start-up/break-in. Failure to do so WILL VOID YOUR WARRANTY.
