Can a Chevy engine run without a camshaft?

Can a Chevy engine run without a camshaft?

Because the camshaft orchestrates the entire valve system, your Chevy won’t run properly without it. Many camshaft number reference sites exist online for V8 engines, but determining the camshaft specs for six- and four-cylinder engines may require contacting a Chevrolet parts department. Remove the camshaft from the engine if necessary.

What kind of camshaft does a General Motors engine use?

The camshaft is a steel roller cam, approximately 4” shorter and .300” larger in diameter, so there should be no problem with misapplications. This engine was introduced in 1965 and with the exception of some of the very early 1965-1966 models, which had an oiling groove in the rear journal, the camshafts are interchangeable.

Are there any problems installing a new camshaft?

By far, the most common problem encountered when installing a new high performance camshaft is the incompatibility of the existing valve springs to the new cam. Factory valve springs are designed to work with stock, low lift camshafts, and since most aftermarket cams have higher lift, the springs must be replaced with compatible components.

What do you need to remove a Chevy Cam?

Remove the camshaft from the engine if necessary. This is an involved process, requiring the removal of the engine’s front end. The radiator, hoses, timing assembly, belts and fan will need to be removed to access the camshaft. This is a job for professionals and the mechanically-inclined.

What kind of camshaft is used in a LT4 engine?

(See note at bottom of page.) NOTE: The Gen-II LT4 camshaft P/N 24502586 was designed to be used in many different engines. The following change may be necessary for correct engine assembly: For LT1 and L98 engines (pre-1996), the dowel pin in the end of the camshaft must be pushed in so extension from end of cam is .30″+/-.01″.

What should I do if I have a camshaft failure?

For extra protection, an anti-wear additive should be added, such as Crane Super Lube. Do not use synthetic oil during the break-in period. It is not recommended to use any type of oil restrictors to the lifter galley, or use windage trays, baffles,or plug any oil return holes in the valley.

What causes a camshaft to fail on a roller wheel?

This high spring pressure causes the heat created at the cam to be transferred to the roller wheel, resulting in its early failure. Any springs that may be used must be assembled to the manufacturer’s recommended height. Never install springs without verifying the correct assembled height and pressures.

What causes the cam to move back in the block?

If the end play is excessive, it will cause the cam to move back in the block, causing the side of the lobe to contact an adjacent lifter. Broken dowel pins or keys. The dowel pin or woodruff key does not drive the cam; the torque of the timing gear bolt, or bolts, against the front of the cam drives the cam.
