if you are refering to the cam timing after installing a new cam, bring #1 piston first piston on drivers side to the top on compression stroke. To check this use a gauge or just insert your finger in spark plug hole(not all the way in just plug) have some one turn the engine over slow, when the compression blows exhaust out that is close to top dead center, next remove valve cover on driver side and check to be sure both rocker arme are on top valves will be closed. If all is well install the timing chain. cam gear will have a dot and the crank gear will have a dot align the dots so that the cam dot is at bottom and the crank dot is on the top.
the mark on the camshaft timing gear needs to line up with the mark on the crankshaft timing gear to ensure the camshaft is in proper time with the crankshaft. Keep in mind that the marks will only line-up every other revolution of the engine due to the crankshaft spinning twice as fast as the camshaft.
A Chevy Cobalt has a timing belt which connects the camshaft and crankshaft. Older model cars often use less effective timing chains.
Trouble code P1345 means: Camshaft To Crankshaft Position Correlation Fault
The dot on crankshaft at 12 o'clock and dot on cam gear at 6 o'clock the centerline of crankshaft, dots on gears, and centerline of camshaft should all be inline.
Does the 1991 2.5 s10 have a timing chain or a belt or just mesh gears and how do you replace them The camshaft is gear driven off the crankshaft. The camshaft gear is pressed onto the camshaft. The camshaft must be removed from the engine to change the camshaft timing gear. The timing gears should last the life of the engine. Next time, please don't answer your question with another question.
were is the cam shaft sensor
The crankshaft sensor on a 2001 Chevy Silverado 8100 is located on the bottom of the engine, near the starter. It constantly monitors where the crankshaft is in its rotation.
you can check your fuel pressure! check the timing, maybe even your crankshaft and or camshaft sensor. maybe weak fuel pump
It has a timing chain for sure.
timing chain
It has a timing chain and gears.
Where is the camshaft sensor located in 1997 Chevy venture
