Installation of Positive Crankcase Ventilation (PCV) Valve/Hose
Chevrolet Performance Parts recommends that the PCV Valve be installed into one of the Rocker Covers and then connected with
a hose to the Nipple on the base of the Throttle Body as shown in the picture below:
A fresh air hose should be connected from the opposite Valve Cover to the Base of the Air Cleaner assembly to supply fresh air to
the crankcase as shown in the picture below:
Start-up and Break-in Procedures
1. After installing the engine, ensure the crankcase has been filled with 5w30 motor oil (non-synthetic) to the recommended oil fill
level on the dipstick. Also check and fill as required any other necessary fluids such as coolant, power steering fluid, etc.
2. The engine should be primed with oil prior to starting. Follow the instructions enclosed with the tool. To prime the engine, first
remove the distributor to allow access to the oil pump drive shaft. Install the oil priming tool. Using a 1/2" dill motor, rotate the
engine oil priming tool clockwise for three minutes. While you are priming the engine, have someone else rotate the crankshaft
clockwise to supply oil throughout the engine and to all the bearing surfaces before the engine is initially started. This is the
sure way to get oil to the bearings before you start the engine for the first time. Also, prime the engine if it sits for extended
periods of time. Install Distributor as follows: (1) Locate cylinder #1 top dead center (TDC). (2) Rotate engine to 12 degrees
before top dead center (BTDC). (3) Install the Distributor so that the Rotor is pointed in the proximity of the #1 stamped on the
outside of the Distributor housing and the short trigger tooth is just entering the distributor sensor. Attach the distributor cap
and plug the distributor into the corresponding 3 pin connector on the engine harness. Lightly tighten the distributor tie down
bolt so the timing can be fine tuned later. Connect the spark plug wires starting with cylinder 1 at the number 1 position and
working your way clockwise with the firing order of 1-8-4-3-6-5-7-2.
