To start with, relieve the pressure in the fuel system and disconnect the battery to remove the camshaft. After that, drain the cooling system and remove timing chain cover, timing chain, phaser, and oil pump. Then remove cylinder heads and radiator. Remove Lash Adjuster rail mounting bolts next and extract Lash Adjusters from bore of Lash Adjusters using a special tool or magnet. Before camshaft removal check endplay and then remove thrust plate of camshaft. Carefully pull it using a long bolt as handle while turning it. To inspect camshaft; look for discoloration on lobes, score marks on lobes, uneven wear on lobes, check bearing journals for wear on journals of bearings measure lobe height for each lobe of camshaft among others things such as this. Check shoves inside Lash Adjuster wall, Lash Adjuster seats valves along pushrod or roller. If new Lash Adjusters are going into engine, new camshaft must also be installed with them. With installation lube apply some lubricant onto both bearing journal as well as the hardened lobes of the camshaft before sliding its nose into place and installing thrust plate for it. Installation is followed by installation of timing chain, sprocket, lubricating Lash Adjusters then finally putting them in block. Finally complete remaining steps in checking if necessary filling coolant system oil filter starting engine checking leaks changing oil breaking components to other new ones that remain.

Follow the reverse order of the removal steps, including changing the oil and installing a new oil filter, filling the cooling system, checking for oil pressure and leaks, and breaking in new components if necessary. Change the oil and filter again after 500 miles of operation.

A special tool may be used to extract the lifters, but they can often be removed with a magnet or fingers. It is advised to avoid using pliers unless the lifters are to be replaced, as this can damage them.

Check the pivot area and shaft for wear, and if any components are damaged, replace them.

Removing the liming chains and the camshafts, which requires major disassembly of the engine and surrounding components.

No, do not attempt to remove the lash adjuster from the rocker arms at any point to avoid damage to both components.

Label and store the rocker arms and lash adjusters to keep them separate for reinstallation on the same valves.

Before starting, if the vehicle is equipped with air conditioning and you plan to remove the camshaft with the engine in place, have the air conditioning system discharged by a professional.

Begin by removing the crankshaft damper and gear housing cover, followed by the radiator, upper radiator support panel, intercooler, and air conditioning condenser. If you opt for Method Two for tappet retention, remove the fuel transfer pump, fuel filter/water separator, and fuel injection pump.

Clean the lifters and check for scuffing and wear on the lifter walls, pushrod seats, and roller lifters.

Remove the lifter rail mounting bolts and use a special tool or magnet to extract the lifters.

Rotate the engine clockwise until the pistons are positioned correctly.

Use the valve spring compressor to depress the valve spring and remove the rocker arm.

Remove the valve cover(s).

For tappet retention using Method One, you'll need wooden dowels to secure the tappets in their bores. Insert the dowels through the pushrod holes and secure them with rubber bands to keep the tappets raised. In Method Two, you'll use small hose clamps to retain the tappets at the top of their bores.
