Read these instructions fully before beginning installation.
-
Professional installation is recommended.
-
Always use high-zinc (ZDDP) break-in oil and a quality oil filter.
-
Replace worn components (timing chain, lifters, valve springs, retainers, etc.) during cam installation.
🛠️ Required Tools & Supplies:
-
Basic mechanic’s hand tools (ratchets, wrenches, sockets, screwdrivers)
-
Torque wrench (ft-lb and in-lb)
-
Harmonic balancer puller
-
Timing gear puller/installer
-
Engine assembly lube (high-pressure moly type)
-
High-zinc break-in oil & new oil filter
-
New camshaft timing set (recommended)
-
New valve springs, locks, retainers, valve seals (per camshaft recommendations)
-
RTV sealant, gaskets (timing cover, water pump, intake manifold, valve covers)
🔧 Installation Procedure:
1. Preparation
-
Disconnect the battery.
-
Drain engine coolant and remove radiator for clearance.
-
Remove serpentine belt, water pump, alternator, and accessories as needed.
-
Remove valve covers, intake manifold, and rocker arms.
-
Remove lifters and pushrods (keep them organized if reusing).
-
Remove harmonic balancer, timing cover, and timing chain/gear set.
2. Camshaft Removal
-
Carefully slide out the old camshaft, keeping it level to avoid bearing damage.
-
Inspect cam bearings for wear. Replace if necessary.
-
Clean all gasket surfaces thoroughly.
3. Camshaft Installation
-
Apply assembly lube liberally to all camshaft lobes and journals.
-
Slowly insert the new TorqueLine 266° / 271° camshaft, keeping it level and supported.
-
Install new timing set (double-roller recommended).
-
Align timing marks at 12 o’clock (cam) and 6 o’clock (crank).
-
Verify true Top Dead Center (TDC) with a piston stop if possible.
-
-
Torque camshaft retainer bolts to factory specifications.
4. Valvetrain Setup
-
Install recommended valve springs, retainers, locks, and seals.
-
Install pushrods and lifters (new lifters recommended).
-
Apply assembly lube to lifter bases and pushrod tips.
-
Reinstall rocker arms and adjust preload:
-
With the lifter on the base circle, tighten rocker nut until zero lash, then add ½ to ¾ turn for hydraulic preload.
-
5. Reassembly
-
Reinstall timing cover with new gasket & RTV at corners.
-
Reinstall harmonic balancer, torquing to spec.
-
Reinstall intake manifold with new gaskets and RTV at end seals.
-
Reinstall valve covers, accessories, and radiator.
-
Fill engine with fresh high-zinc break-in oil and coolant.
6. Startup & Break-In
-
Prime oiling system with a priming tool before startup.
-
Set initial ignition timing to 12°–16° BTDC (depending on build).
-
Start engine and immediately bring RPM to 2,000–2,500 RPM for 20–25 minutes to seat lifters and ensure proper oiling.
-
Check for leaks, abnormal noises, or overheating.
-
After break-in, change oil and filter.
