Hook up the timing light to the number one cylinder and start the engine. Aim the timing light at the marks. If the timing marks do not come close to alignment or you do not see any alignment at all, it means the chain has jumped position.
Situations such as an engine overheating or running out of oil can cause a piston to seize within the cylinder. If this happens while the engine is running at a high rpm, the sudden stop in rotation can cause a timing chain to fail.
There is no easy way to correct a jumped timing belt. You will need to disassemble a portion of the engine to gain access to the belt tensioner, so you can move the belt back into position. I suggest replacing the belt and tensioners while you have it apart, so you don’t have this problem again.
On average, you’re going to be looking at paying somewhere between $1,290 and $1,550 for a new timing chain for your car. That price includes all the necessary parts, which will run you just under $400, and labor, which is going to cost more than $1,000 in many cases.
Engine Won’t Start: If the engine timing belt has broken, it won’t be able to start. You may hear it “engage” as it is trying to start as you turn the key, but because the engine timing belt is what operates the camshaft and crank that turns the engine, it isn’t able to start.
Typical costs: Hiring a mechanic to replace a timing chain typically costs $300-$1,000, depending on the make and model of the vehicle, its age and whether the work is performed at a dealership or an independent shop. Purchased separately, a timing chain typically costs $50-$250 or more.
An engine with a jumped timing chain will show signs of very sluggish and slow starting. This happens because the firing sequence is retarded due to a chain that has jumped a tooth. A chain that has jumped two or more teeth may not start at all.
You can determine if it is 180 out by removing #1 plug and placing your finger/thumb over the hole. (Temporarily remove the wire from the coil first) Have someone “tap” the starter and you will feel pressure trying to to blow your finger away. This is the compression stroke. Note the direction of engine rotation.
alright well recently i turbo’d my 99 eclipse n/t afterwards i drove it about 3-4 miles drive great slight fuel cut… well the car wouldn’t the next morning so i figured id tear it down i replaced head gasket,timing belt,tensioner pulleys and,water pump and motor has recently been head reconditioned,pistons+rings, …
Unless there is a specific problem, the timing chain normally needs to be replaced between 80,000 and 120,000 miles. If you drive an older vehicle, or one close to 100,000 miles, you should have it replaced or at least become aware of the symptoms of a failing timing chain.
The simple answer is No, it is not. Timing chain problems are not uncommon, especially in high-mileage vehicles. Like any other moving mechanical component inside any engine, a timing chain is subject to wear. A timing chain is lubricated by the engine oil.
illuminated check engine light: the car’s computer monitors engine operation to ensure emissions don’t get too high. a stretched timing chain will hurt engine performance and increase emissions. if this happens, the computer will turn on the check engine light and store a diagnostic trouble code.
Listen for a metallic sound that resembles a rattling or scrapping noise. The sound can be intermittent or constant, but it will be a metal to metal contact. … If you hear a rattle, metal to metal slapping or scraping coming from inside the cover, it indicates a timing chain noise.
At minimum a jumped timing belt will cause a noticeable running problem and/or a Check Engine Light. In many cases a jumped timing belt will cause some engine damage. A timing belt can also strip teeth off, shred, or break entirely.
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.
The most common cause of timing chain stretch is lack of maintenance and regular oil changes. … Worn out oil can no longer lubricate the chain and will cause the rollers and links to wear against each other.
The Best in Auto Repair The average cost for a BMW 328i timing chain tensioner replacement is between $707 and $857. Labor costs are estimated between $572 and $721 while parts are priced at $135.
If the timing is off, damage can occur. In some engines, called “interference engines,” the consequences can be especially bad. … You could end up having to have your engine rebuilt, or even replaced. If your cam timing is off, chances are you’ll know because your car will not be running well, if it’s running at all.
180* off means that the rotor is roughly pointing at the #6 plug wire on the cap at TDCC. Won’t run like that. Sounds like you’re timing is retarded like John mentioned. Check that the firing order on the cap is correct.
The rotor button should be pointing to the number 1 position on the distributor cap when the number 1 piston is at top dead center (on the compression stroke). The pistons come up two times during the combustion cycle.
Once the top dead center timing mark is lined up with the marker on the engine, the motor should now be at top dead center. To verify, shine the flashlight down into the spark plug hole. You should be able to see the top of the piston clearly near the top of the cylinder.
A compression test indicates if an engine has worn piston rings, a bad valve, a leaking head gasket, or if the engine’s valve timing is off. … The results of a wet compression test can be quite telling.
If you have car engine compression problems, your car will either misfire when you start the engine, perform poorly or, if you have low or no compression in all cylinders, won’t start at all. You can’t drive your car for long, if at all, with low compression.
How much does timing chain replacement cost in the UK? The cost of timing chain replacement for most cars is on average between £500 and £1,300. This is made up of the cost of materials for the timing chain and labour for the replacement.
