Can a timing chain be checked?
A timing chain might become loose if the belt tensioner breaks, the gears get worn, or the chain itself gets stretched. A loose timing chain can throw the engine’s timing off, which can lead to poor performance. If you have experience as a home mechanic, you can check the timing chain in a series of steps.
How do you check timing chain deflection?
Timing cover off,by using a hard straight edge over the top of the chain, from one gear edge, to the other gear edge…Then push on the chain,(near the middle) away from the straight edge… Measure the distance that the chain “deflects” away from the straight edge.
How do you fix timing problems?
To adjust your timing, all you need to do is turn the distributor housing one direction or the other, depending on whether or not you want to advance or move back the timing. If the rotor turns clockwise, you’ll advance the timing by rotating the distributor counterclockwise, and vice versa.

Why do I need to check the timing on my engine?
Valves may already be biting into the pistons and you may cause more damage. Should the engine turn freely by hand and you have easy access, position the crank and check the timing marks on the crankshaft and cam.
What should I do if my timing cover is taken off?
Anytime you take a timing cover off, take a quick look at the timing marks, then check for excessive backlash, gear or sprocket wear and belt or chain play. Also check for clogged gear or chain lube drains. High-mileage engines may need a new chain, gears or belt just as a safeguard, before timing failure sets in.
How can I check the timing of the distributor?
First, see if the snake moved! To check valve timing on engines having a distributor that’s driven either directly or through the cam, first remove the distributor cap. If you turn the crankshaft by hand in the direction of normal engine rotation and the rotor doesn’t move, suspect a completely broken drive.
