What kind of camshaft does a V8 engine use?

Most American-made V8 and V6 engines use in-block camshafts, which means you may have to pull the engine out to do the swap. Many engines using overhead camshaft configuration actually have multiple camshafts, such as a Dual Overhead Camshaft (DOHC).

When does it make sense to replace a camshaft?

A warped cylinder head could theoretically also warp the cam shaft but i would not just replace it, i would check it first. Place the cam in a set of V blocks. Put a dial indicator on the bearing surface and spin the camshaft. Watch how much the dial indicator deflects. The appropriate engine manual will have the warpage specs.

How do you remove the thrust plate from a camshaft?

Remove the thrust plate from the front of the camshaft by removing the plate’s two retaining bolts with a wrench. Grasp the end of the camshaft and pull it out of the engine while simultaneously twisting it to complete the process.

What does the gear at the end of the camshaft do?

The camshaft also features a gear at one end of the camshaft which tells the engine’s distributor when to send a spark to the spark plugs. Over time, the camshaft’s lobes wear down, resulting in poor performance and fuel economy.

What kind of socket do I need to remove camshaft?

A 10 mm socket is needed to remove the two bolts in each coil that secure it to the valve cover. Pull the PCV hose off the valve cover. Remove all the bolts in the valve covers using a socket.

How do you remove a camshaft sprocket on a Chevy?

Use the screwdriver to pry the timing chain cover off. Straighten out the bolt lock ring behind the bolts on the camshaft sprocket. Use a screwdriver to bend the tabs back so the bolts can be turned. Remove the three bolts in the camshaft sprocket using a socket. Pull the sprocket off the camshaft and remove the timing chain.

How do you remove a cam from an engine block?

Remove the old cam. Though using a camshaft removal tool is ideal, if your budget is tight you can work the cam out of the engine block by twisting it slowly and carefully, taking precaution not to scratch or gall the bearings.

How many camshafts does a DOHC engine have?

Many engines using overhead camshaft configuration actually have multiple camshafts, such as a Dual Overhead Camshaft (DOHC). If you have a DOHC engine which is also a “V” configuration it is possible to have as many as 4 camshafts. Access the camshaft.

What’s the best way to install a camshaft?

Using your ratchet and socket, remove the center bolt on the camshaft gear and remove the gear from the camshaft. Step 16: Install the camshaft gear onto the new camshaft.

Can a camshaft be removed from a cylinder head?

Warning: When removing the camshaft, you want to make sure that it does not fall, as it can damage the bearings in the cylinder head. Step 15: Remove the camshaft gear. Using your ratchet and socket, remove the center bolt on the camshaft gear and remove the gear from the camshaft.

Where do you put the timing disc on a camshaft?

It is always recommended to calculate the actual position of TDC rather than rely on the mark on the crank pulley. Fit the timing disc to the front of the crankshaft. A pointer for the timing disc can be made from a piece of bent wire secured under a suitable front cover bolt. Position a dial gauge to measure the travel of No 1 piston (see right).

What should the timing be on a Burton power camshaft?

Now rotate the crank clockwise until the inlet valve of number one cylinder is just off full lift position (such as 0.005” or 0.15mm). Record the figure on the timing disc from the pointer. Then continue to rotate the crank clockwise until the valve has fully opened and then closed by the same distance as previously used (0.005” or 0.15mm).

Which is easier to access overhead camshaft or overhead valve engine?

To access the crankshaft compartment, you may have to pull the entire engine, depending on the type of engine and the make of the vehicle. Overhead Camshaft (OHC) engines are much easier to access than Overhead Valve (OHV) type engines, with the camshaft centered in an engine block.

How does an overhead valve work on a camshaft?

Since the camshaft is below the valves what with the valves higher up and above the pistons, we get the term “overhead valve”. As the camshaft rotates, lifters ride on the camshaft lobes which raise the pushrods. As the pushrods rise, they push one end of the rocker arm which in turn pushes the valve down and opens it.

Can a camshaft be removed from a radiator?

Once this occurs, the camshaft must be removed and replaced with a new camshaft. Drain and remove the radiator. The radiator can be drained by removing the plug on the bottom of the radiator with a wrench.
