Having a problem with timing

While I got #1 on TDC my timing chain marks are good but distributor is pointed at front of engine
My car has a manual transmission.
Experienced mechanics share their insights in answering this question :
Hi and thanks for your question. Remove the distributor and turn the gear one tooth to make the rotor face the number one cylinder and tighten it down. Then mark the bottom of the distributor where the rotor is facing and put the cap on. Turn it to where number 1 is aligned up at it.

This will ensure that the distributor is set at TDC. You may have to adjust the distributor cap, if you can, to the right setting for the best performance. I recommend having a certified mechanic, such as one from YourMechanic, inspect for any problems and replace the Top Dead Center sensor if you think it may be bad.

Definition of `ignition timing`

Ignition timing is the timing of the spark relative to the piston top dead center in a spark ignition engine. You can adjust the ignition timing to suit a fuel of a lower octane rating. The ignition timing ensures that the spark plug ignites the fuel at the optimum moment.

Each truck sported a four-speed automatic overdrive transmission.
Signs Your Ignition Timing Is Off

Some things to look out for: Engine knocking: Engine knocking occurs when the air-fuel mixture is ignited too soon in the cylinder. The mixture then pushes against pistons that are still trying to compress the mixture. This causes loud pinging sounds to come from the engine.

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.
The relationship between crank and cam timing events can also cause no spark, especially on Chrysler products. On these vehicles, the PCM won`t trigger the ignition coil if the cam and crank are out-of-sync.
Ignition timing fully under the control of the engine management system with spark timing determined by the throttle position, engine speed, knock sensor, engine temperature, and manifold vacuum.

Pre-owned Chevrolet C/K 1500 Series models are available with a 4.3 L-liter gas engine, with output up to 160 hp, depending on engine type.

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. The valves themselves will bend and potentially ruin the engine.
A malfunctioning timing chain can cause the engine to misfire, run poorly, or even seize up, leading to catastrophic engine failure. As such, it is crucial to ensure that the timing chain is regularly inspected and that any issues are addressed promptly to prevent costly repairs and potential damage to the engine.
Timing chains are made of metal, but over time and through exposure to high heat and physical stress, they can suffer from wear and tear. Eventually, they will break. These chains look very similar to bicycle chains and are made with similar links.
Timing belt or chain problems

This will result in a loss of power, often accompanied by a rattling noise from the engine.

When the timing belt breaks, the crankshaft will continue to spin, while the camshaft will stop turning. As a result, the pistons will continue to rise and fall in their cylinders and can, in some instances strike the valves.
If the spark timing is initiated too early, the cylinder may experience detonation and potentially cause damage. If the spark occurs too late, the engine runs flat, makes less power, and may overheat.
Most engines have between 5-20 degrees of ignition advance at idle. This is referred to as initial timing.
Will Timing Chain cause Misfire? Your Engine will misfire because your Timing Chain has been stretched from age and everyday wear and tear, once it is stretched the Belt loses integrity causing the chain to skip gears and misfire.
Many supposed carburetor-related problems like low-speed hesitation can be traced to improper ignition timing.
Over-advanced timing may not only damage engine components, but may also negatively impact fuel economy. Many technicians mistakenly believe that advancing timing beyond the factory specified range can improve mpg. This is inaccurate and a misconception.
A Bad Crankshaft Position Sensor

The crankshaft position sensor monitors the position and rotational speeds of the crankshaft. Without the crank sensor, the engine control module (ECM) wouldn`t know when to fire the fuel injectors and ignite the spark plugs.

Advancing ignition timing increases engine temperatures. As you increase towards MBT you get more power but temperatures may get so high that you melt a through the combustion temperature + compression increasing temperatures.
The top three methods for controlling timing are chains, gear drives, and belt drives.

1992 Acura Legend, when the timing belt goes, is it common for the valves to bend?
ANSWER : If the timing belt break off, the engine’s pistons will hit the valves as the pistons are moving. The engine is an interference engine and can cause damage to the internals of the engine. The last time the belt came off, the engine may have been running at an idle or not under power. It is possible for the valves to be bent. What I recommend doing is performing a leak down test on the engine with a timing belt on the engine and properly timed to determine if the valves were in fact bent. If all of the cylinders have a 80 percent hold and not leaking, then the engine is fine. If there is a mass leak on a cylinder, then the piston did some internal damage. I recommend seeking out a professional, such as one from Your Mechanic, to help you check your engine’s valve train with a leak down tester.

Every time I start my car the first time I turn my wheel I hear a pop then no problem no more sound and steering seems to work fine.
ANSWER : Sounds like your have bad strut mounts and a broken spring with the spring popping in and out and then getting reset as the spring pops into place. Check the front springs and see if they are cracked or damaged. If the spring is broken, then I suggest replacing the strut assembly. If you need further assistance with your front end making a popping noise when turning the steering wheel, then seek out a professional, such as one from Your Mechanic, to help you.

Timing chain positioning
ANSWER : This system is a bit complex. I can give you some instructions, but I highly recommend getting a hold of a repair manual or purchasing a yearly subscription for just your vehicle from AllData. It is only $25 for a years subscription from AllData.

There are two separate sets of marks on this system. One set is for aligning the timing chain to the camshaft gears and the intermediate shaft gear. There will be marks on the chain that raps around the crankshaft gear as well. These marks will not line up after you turn the motor over.The other marks are on the inside of the camshaft gears and align with the cylinder head parting line. If you were to draw a ling through the center of both camshaft gears, they should line up with that imaginary line.

The crankshaft key way should be aligned with the mating face of the main bearing cap. You can confirm it is in the correct position by verifying the number one piston is at top dead center. If you have removed the balance shaft timing chain, these marks really need a visual diagram to understand where they should be aligned. Without a diagram I am not very confident it can be explained very clearly.

This may be difficult to to follow, so again I highly recommend purchasing a repair manual in digital form or a book. If you feel this is over your head, I recommend the following inspection to help you out. Timing chain replacement

Good luck! I hope I was able to help you.

Problems starting my car. It cranks strong but for a long time – 2012 Chevrolet Silverado 1500
ANSWER : Hi there. A malfunctioning mass air flow sensor may create the extended crank concern; however, a sticking idle air control valve can create the same concern. Cleaning of either components has been known to help with the situation. However, this is rarely a long term repair and is only temporary.

You could clean one at a time and see which one alleviates the extended crank and replace as necessary. Also, there may be a residual fuel pressure problem. Residual fuel pressure is the pressure that remains in the fuel lines and injectors to provide immediate start up fuel. If the check valve in the fuel system is bleeding off, this could definitely be the cause. However, since it is only 10% of the time, it may be difficult to verify.

I recommend having a certified technician, such as one from YourMechanic, assist you with an idle speed inspection to determine if a mass air flow sensor replacement or idle air control valve replacement may be necessary.

My 2010 Chevrolet Equinox has a timing chain replaced and I was wondering if the timing gear was part of this.
ANSWER : Hello. If they replaced the timing chain to begin with then they should have also replace the timing chain gears and the tensioners at the same time. If they did not replace all of these parts when then installed the timing chain then they did not do a good job of repairing the vehicle. If the tensioners continue to fail due to a lack of oil pressure then there are other issues with the engine. It may have a failing oil pump. If you need some help with this engine, consider YourMechanic, as a certified mechanic can come to you to [diagnose why the tensioners keep failing] https://www.yourmechanic.com/services/timing-chain-replacement

At times my jeep will start fine and at times I have a hard time getting it to start. It seems like the wireless ignition node is
ANSWER : The recommended diagnostic to resolve this is a hard starting diagnostic. The work is performed by a certified mechanic right at your location. Among the first things the mechanic will check is whether required maintenance is up to date because old spark plugs, clogged fuel and air filters, and the like are potential causes of the hard starting you are describing. Other possible causes include a failing coolant temperature sensor, or bad connection to the sensor, problems with other sensors such as the cam and crankshaft position sensors, a defective fuel pump, and many other causes, all of which will be familiar to YourMechanic’s experts. With regard to the fuel pump, if the engine is not getting enough fuel it will be hard to start. If you request a hard starting diagnostic, YourMechanic will get this issue diagnosed and resolved for you.

I want to find out IF you think it is USUAL to fix a popped timing belt but then just have one problem after another after another
ANSWER : Hi there:

First off, I’m sorry to hear about your husband. Our thoughts are with you. In regards to the timing belt issue on your Nissan Maxima, the mechanic is slightly correct. When the timing belt breaks inside the motor, it’s very common for other mechanical components to fail including the cam shaft, cylinder head hardware and other really expensive parts. The reason it’s a guess is because it’s impossible to know for certain when the belt broke and what damage has occurred without completely rebuilding the motor. The fact that the mechanic gave you that honest advice is a good indicator that they’re actually looking after your long term best interests; as most shady mechanics would charge you the $900.00, and wait for other damage to occur so they could continue to make money off that issue. Although I’m not there to inspect it myself, i’d tend to agree with the other mechanics opinion. If you end up buying a newer vehicle, make sure to have one of our professional mechanics complete a pre purchase inspection; which will allow us to complete a 150 point safety inspection to ensure you don’t buy a lemon.
