Many reasons. Extreme valve spring pressure, sometimes if gear driven, the crankshaft will transmit vibration, thus breaking it, or maybe a connecting rod let go, and hit it. Or, it could have been a weak casting, though that is uncommon. These are the only reasons I have seen, in the field.
no
A camshaft seal keeps engine oil in and dirt/water out.
A two-stroke engine does not have a cam or camshaft. Seeing there is no intake/exhaust valves it would be pointless to have a camshaft.
The camshaft operates the valves on a 4 cycle engine.
First, find the camshaft sensor. It will be right in the front of the engine near the valve cover. Disconnect the plug and remove the bolt. Pull the camshaft sensor out. Insert the new camshaft sensor and reattach the plug.
It can depending on what you do to it.
A camshaft can break for several reasons. The shaft could have a defect causing it to break, or something in the engine could bind up and put pressure on the camshaft, causing the damage.
Yes any camshaft can break if something goes wrong.
Hmm, as a rule they don't break, although Chevy had a problem with soft camshafts "rounding." A broken camshaft would make quite a horrible racket when the engine is turned. You most likely do not have a broken cam shaft.
It's usually caused by improper break-in procedure, but can also be caused by burrs in the lifter bores preventing the lifters from revolving or improper break-in oil.
The camshaft closest to the intake manifold (closest to the passenger cabin) is the intake camshaft on the dual camshaft Saturn engines.
no
by the camshaft
NO. If the camshaft is broken it will not run. If the camshaft is worn it will run poorly.
The camshaft TDC mark is located on the camshaft side of the pulley wheel. When the mark is level with the front reinforcing strip on the camshaft cover the camshaft will be at TDC.
On the camshaft
Valve timing will be off for one, and the car will not run right. If you have an interference engine you may get catastrophic damage from a piston contacting an opened valve. Since these parts don't tend to break very often, and when they do it is a major repair; what are the symptoms that would have you thinking camshaft?
