When you re-install the timing chain, you are supposed to push the chain guides in while tightening.
Timing chains can be adjusted to either loosen or tighten the timing chain so that it runs smoothly along with the timing chain tensioner.
Beside this, How much does it cost to tighten a timing chain?
For most cars, a timing chain replacement costs between $413 and $1040, or you can order the parts themselves for $88 and $245. It is a tricky repair though, so unless you’re particularly skilled it’s usually best left to a mechanic.
Likewise, Can timing chain be to tight?
To tight would be not being able to get the gear onto the cam dowel, to loose would be having slack on the gear before the engine is run. Like I said as soon as the engine starts the chain will be a little looser.
Also, How much does it cost to replace timing chain tensioner?
Timing Chain Tensioner Replacement Cost – RepairPal Estimate. The average cost for timing chain tensioner replacement is between $906 and $1,108. Labor costs are estimated between $764 and $964 while parts are priced between $141 and $144.
How do I know if my timing chain tensioner is bad?
– Engine may stall or run rough.
– Noise in the front of the engine (a rattle or rumble, associated with engine speed)
– Check Engine Light may illuminate and set misfire, camshaft sensor, and crankshaft sensor codes.

One of the most common symptom of a bad or failing drive belt tensioner is noise from the belts or tensioner. If the tensioner is loose the belts may squeak or squeal, especially when the engine is first started.
Can you tighten a timing chain?
Timing chains can be adjusted to either loosen or tighten the timing chain so that it runs smoothly along with the timing chain tensioner.
What are the symptoms of a bad timing chain?
– Engine misfires or runs poorly.

What causes timing chain tensioner failure?
The most common cause of timing chain stretch is lack of maintenance and regular oil changes. … The bad oil can also damage the tensioner which makes the possibility of the engine skipping time or a catastrophic failure even greater.
How much play should be in a timing chain?
As mentioned, 1/2″ deflection is considered max. A worn timing chain won’t cause a miss … not until it’s so worn it jumps a tooth (and then you’ve got a lot more problems than a miss *LOL*).
Is a belt tensioner supposed to move?
Appearance: Move the tensioner arm (tensioner being mounted on the engine) through its entire range of motion with a wrench. There should be resistance to this movement. If there is none, the spring has lost its force. Other indicators are belt squeal from slippage, or loss of rotation of a belt-driven component.
Is the belt tensioner supposed to spin?
New belt tensioner pulleys do not free spin much.
What does a bad timing chain tensioner sound like?

How many miles is a timing chain good for?
120,000 miles
How do you rotate a belt tensioner?
Rotate the pulley on the belt tensioner counterclockwise to relieve the tension of the belt with the proper sized socket and ratchet.
Do timing chains really stretch?
The most common cause of timing chain stretch is lack of maintenance and regular oil changes. … As the chain runs around the gears of the camshafts and crankshaft, the movement between the rollers and links causes wear and elongation. As the timing chain wears, this can change the timing of the camshaft and crankshaft.
How tight should a belt tensioner be?
Pinch that point between your index finger and thumb and move it back and forth. The belt should have about a half an inch of play when at the appropriate tightness. If there is less than a half an inch, the belt will need to be loosened, if there is more, it will need to be tightened.
