What do I need to replace timing chain on VQ35DE engine?
I’m doing it with the engine out of the engine as I’m swapping it into a 5.5 Gen, so the upper oil pan is already removed and I’ll be going from there. Most stuff I’ve seen in my travels says to replace all three chains, the main tensioner, the top guide, the slack guide, and the two small guides in the camshaft chains.
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.
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.
What’s the best way to remove a timing chain?
Put the bolt partially back in the bolt hole and use a harmonic balancer removal tool. The tool should not be a jaw type tool, but instead should apply all of the removal force to the center of the assembly. This protects the rubber ring in the harmonic balancer. Remove the timing chain cover.

Do you have to install new tensioner when replacing timing chain?
If you’re replacing it, the new tensioner should come with a pin already installed in the hole. Leave it in place until you’re completely done with the chain installation.
Where is the hole in the timing chain?
With TDC set, tension can be relieved from the chain. The main tensioner has a small hole in it, and the piston itself has a deep groove near the end of the piston.
Do you have to remove oil pan to change timing chain?
You don’t have to remove the upper oil pan to pull the timing cover, but you DO have to unfasten the two bolts that attach it to the cover. If you don’t, you’ll split your cover when trying to pry it free. This means you must remove the lower oil pan to get to those two bolts.

Why does my Infiniti I35 make a rattling noise?
Rattling and tapping in the front of the engine on the 2002-2004 Infiniti I35 is very evident, especially on cold starts. This rattling noise should not be taken lightly as it warns of upcoming timing chain failure. The cause of the noise is faulty timing chain guide rails and timing chain tensioners that wear out well ahead of schedule.
What causes the noise in a timing chain?
The cause of the noise is faulty timing chain guide rails and timing chain tensioners that wear out well ahead of schedule. These components are there to keep the timing chain tight and properly positioned.
How much does an oil change cost on an Infiniti I35?
To remedy the situation, Nissan/Infiniti has made revised guides and tensioners, but replacement can be very costly. Proper oil change intervals and oil type may help slow or prevent the situation. The average cost for a Infiniti I35 General Diagnosis is between $110 -$139.

Can a bad timing chain cause an engine to misfire?
Engine misfires. The timing chain method is more common with consumer vehicles and high performance engines. Over a period of time, the timing chain can stretch, which can cause the chain to skip a gear on the cam or crank shaft. This results in the engine’s timing to fall out of calibration and often results in a misfire.
What are the symptoms of a worn out timing chain?
Listed below are 5 of the symptoms of a worn out timing chain. If you notice any of these warning signs, it’s advised you contact a local mechanic as soon as possible to diagnose the exact cause and make appropriate repairs as needed. 1. Engine misfires or runs poorly There are two ways to achieve valve timing in a combustion engine.
How much does it cost to replace timing sprockets on Infiniti QX56?
An abnormal noise may develop from the timing chain area, Our technicians tell us it may be necessary to replace the variable valve timing camshaft shaft sprockets to correct this concern. The average cost for a Infiniti QX56 General Diagnosis is between $110 -$139.
When do you need to replace the timing chain?
If this situation occurs, it’s likely the timing chain is damaged and needs to be replaced as soon as possible. If the timing chain breaks, the loose metal rolling around inside the motor can lead to serious engine damage. 2. Metal shavings found in the oil
Why is the timing chain on my Nissan club breaking?
It would rattle everytime I start the engine after it was sitting for about 1 hour or so. Sometimes it would rattle sometimes not. Finally I openned the cap where the main timing chain tensioner and I saw that main timing chain guide broke. Usually it brakes from the top and slides down. Therefore the main tensioner fully extends.
What was the problem with my timing chain?
My car’s problem was a rattle during start up. It would rattle everytime I start the engine after it was sitting for about 1 hour or so. Sometimes it would rattle sometimes not. Finally I openned the cap where the main timing chain tensioner and I saw that main timing chain guide broke.

When did Nissan know about the timing chain problems?
The lawsuit claims that Nissan has known about the defects since 2004 and references a Technical Service Bulletin (TSB) that Nissan sent to its dealers regarding “buzzing and whining noises” from the timing chain. As part of the TSB, dealers were told to offer “goodwill adjustments” to owners, but only those that specifically asked for it.
What happens if a timing chain tensioner fails?
Failing of a timing chain tensioner can occur slowly and if you do not catch it in time the slapping chain and lead to a number of engine related problems – some catastrophic. In this video I will show you how to test a tensioner on the bench by comparing one that has failed to a brand new one.
Where is the timing chain in an engine?
Every internal combustion engine has a timing chain or belt. It’s in the front of the engine attached to a set of gears and pulleys that power components like the crankshaft and camshaft. A properly tensioned chain is critical to maintaining the timing between the pistons and the valves.
Are there any timing chain problems on the VQ35DE?
I would like to do a write up about timing chain problems on VQ35DE engines. I’ve done a lot of searching on the forums about timing chain problems on VQ35DE.
