What happens to the timing chain on a Chevy 350?
The timing chain on a Chevrolet 350 engine (also known as the 350 SBC, for small block Chevy) rotates the camshaft in synchronization to the crankshaft rotation. After years of service (or tens of thousands of miles of use) timing chains can stretch. This can affect the performance of the engine.
How do you change the timing chain on a radiator?
Trace the radiator hoses from the radiator back to the engine. Squeeze the hose clamps with pliers and slide them back onto the hose. Wiggle the hose to break it free and move it out of the way. There is no need to remove the radiator.
What are the bright links on a timing chain?
Locate marks or “bright” links in your timing chain. These links are brighter than the other links and are used to align your engine. Set your engine to top dead center. To get your engine to top dead center, line the bright links on the timing chain up with the marks on your camshaft and crankshaft gears.
How are gears connected to the timing chain?
Locate marks on your crankshaft and camshaft gears. These gears are connected by the timing chain so that the position of the piston (connected to the crankshaft) correlates directly to the opening of the fuel and exhaust valves (operated by the camshaft) to keep your engine running smoothly.

Can a bad timing chain cause an engine to fail?
3. Engine won’t start or fails. A broken timing chain will cause an engine to not start or fail while driving. If the belt is already broken, the engine won’t have enough compression to start. If it breaks or jumps while driving, the pistons will be damaged from contact with the valves.

How to install timing chain on a V8?
Slowly bring timing mark up and line with tab. THEN insert distributor pointing at number 1. This will get you back to where you should be. Edited by dbradley on 05-11-11 11:05 AM. Reason for edit: No reason given. Yeah, its a v8, 283. One revolution would put me to the intake stroke on #1.
Can a timing chain be turned 360 degrees?
Yes, turning the crank 360 degrees when the timing marks point at each (TDC on #6) other will move the timing gear up to 12 o’clock. It is fairly common for shop manuals not to identify the difference – so a LOT of people install the distributor 180 degrees out, and don’t know why their motor won’t start.
What do you need to know about timing chain?
SO, if you installed the distributor 180 degrees out, all you need to do is rotate the distributor one half turn. So, if you bring the crank to TDC – and both valves are closed on #1 – you can set the distributor to fire the #1 plug. That is all you need to know to get your truck running.
Do you have to drop timing chain cover?
NO! I’ve removed the timing chain cover from too many SBC’s without dropping the pan to recall how many dozens I’ve done! You pry it of from the top and it’ll pop right out. Now getting it back in is the tricky part. You need to take tin snips an trim the edge of the where the pan to cover meet so you can “pop” the cover back on.
What does the timing chain do on a car?
Your timing chain serves as a link between your crankshaft and camshaft to assure the two are in time. A gear on the crankshaft drives the camshaft (s) that activates valves during the proper piston stroke. When the chain stretches out it can affect the ignition and valve timing.
How much torque do you need for timing chain?
If no damage is visible, you can save time by not replacing it.) Tighten the cam sprocket bolts to 20 pound-feet of torque. Apply a modest amount of gasket sealer/adhesive to the mating surfaces of the timing cover and engine block. Reinstall the timing cover with 6 pound-feet of torque to each bolt.
