Where is the chain tensioner on a Porsche?
Porsches typically have three tensioners. One near the air conditioner compressor (bank 1-3), one by the crankshaft (IMS chain tensioner or also known timing chain tensioner for intermediate shaft), and one on the left bottom corner of the engine (bank 4-6).
Can a IMS chain tensioner be replaced in a Porsche?
Porsches have up to three tensioners. IMS chain tensioner and bank 4-6 tensioner can be replaced with the engine in the car. Bank 1-3 tensioner may require accessories to be removed to access it. Use a 27mm socket and ratchet to break loose the tensioner.
How do you change the timing chain on a Porsche?
Place a socket on the crankshaft pulley and rotate the crankshaft to bring it to TDC. Use the Porsche timing tool or an 8mm Allen wrench to lock the crank pulley to the block. Lock the crankshaft (and, when required, the camshafts) in position.
How do you replace a timing chain tensioner?
Use a 27mm socket and ratchet to break loose the tensioner. Note that the tensioner has lots of threads; therefore, it will take a lot of turning to remove it. Replace one tensioner at a time.
How to replace timing chain tensioner on Mercedes W124?
Begin by installing a new washer (yellow arrow) and the tensioner housing (red arrow) back into the engine and torqueing to spec. Next install the thrust pin (yellow arrow) and detent spring or clip (red arrow) into the tensioner housing. Then install the spring (green arrow).
What can cause a timing chain to fail?
A timing chain can also fail due to a lack of tension. You see, a collection of tensioners and guides hold the chain snuggly in place. Should any of these components break, the chain will be free to slap around against other components, such as the timing cover. Obviously, that can cause severe damage to the chain.

What happens to the timing chain in a car?
Timing chains are the critical link between the crankshaft and camshaft. Through a series of guides and tensioners, the chains are responsible for keeping the cylinder head valves in sync with the combustion chamber pistons. If the timing chain becomes loose, either by stretching or a failed tensioner, there are serious problems ahead.
When do you get reimbursed for timing chains?
There will be no reimbursement for out-of-pocket costs of any repairs or replacements to the timing chains, tensioners or engines if the work was performed more than 30 days after the settlement notice date by anyone other than an authorized Audi or VW dealership.
How do you replace the tensioner on a Porsche?
Use the Porsche timing tool or an 8mm Allen wrench to lock the crank pulley to the block. Lock the crankshaft (and, when required, the camshafts) in position. It is crucial to lock the crankshaft to prevent the timing chain from jumping when the tensioner is removed.
Why to change timing chain?
Improved fuel economy – Changing the timing chain is also going to improve the gas mileage in your car. A new timing chain will ensure that the crankshaft and the camshaft are working perfectly in unison. This ensures that the valves on the engine are able to deliver great combustion. In the end, you will save a lot on fuel costs.
When is it time to change timing chain?
A timing chain is a major component used to keep an engine’s timing in sync, and replacing it is often an essential part of automobile maintenance. Timing chains typically last longer than timing belts and are preferred by some automakers for their durability. Most experts recommend replacing a timing chain every 100,000 miles or so.
When do you need to change the timing chain?
The timing chain normally needs to be replaced between 40,000 and 100,000 miles unless there is a problem. Issues with the chain are pretty common in high mileage vehicles, so if you are driving an older vehicle, or one with a lot of miles, it is best to be on the lookout for symptoms of the timing chain going bad or failing.
How many hours does it take to change timing chains?
How Long Does It Take to Replace a Timing Chain? The timing chain replacement cost is higher than many other auto repair jobs in large part because of how long it takes to put a new timing chain into place. Oftentimes, it’s going to take a mechanic between 4 and 6 hours to complete a timing chain replacement job from start to finish.
