Timing chain replacement interval for 2010 4.6

[WestPennGen]

I just cleared the 225000 mile mark and was wondering how long people have gone before doing timing chains. Mine are still quiet as far as I can tell and I don't see any reason to replace them until they start making noise.

As far as I know you don't replace timing chain.
Timing belts are a different story.

Not true. Timing chains stretch over time and will need to be replaced. I did this on my truck. Just don't know how long the genesis ones last.

No argument about this, but let me clarify my original statement.

Timing chains do not have scheduled replacement interval (like timing belts) and don't need to be replaced, unless they stretch for some reason or have another issues. Sometimes you just need to adjust timing chain tensioner if necessary.

Timing belts, on the other hand, do have scheduled replacement interval (I think every 60K miles) which is indicated in the vehicle manual.

And you are already at 225,000 miles and your timing chain in your Genesis is doing good. If you had timing belt you would probably be on the 4th one.

And welcome to the forum.

Thanks for the welcome. I was asking to see how long people have gone before needing to replace them or how how many miles people have without having replaced them yet. To get an idea of the longevity of them. Would also like to know if people have had issues with the timing tensioners.

My 2006 3.3 LV6 Sonata had 255K miles when I traded it in, no issues with timing chains. The car was photoed and driven away while I waited t take delivery of my current 2014 Genesis 3.8L V6 with 214,600 miles on it from new by me. That engine sounds just like the day I bought it.

Preemptive timing chain replacement just isn't a thing (except for a few engines with flawed designs). By the time the chain really needs to be replaced, a lot of other stuff does too.

No doubt and it might be catastrophic.

Currently doing "a lot of other stuff" as you put it. Alternator has already been replaced. Getting ready to replace valve cover gaskets, thermostat, water pump, belt tensioner, idler pulley, belt, spark plugs, throttle body, hood support, and the entire front suspension. Still cheaper than a new car.

Obviously we are talking a few years difference, plus different mfg and all - but the 2.4 engine in the 2005 Accord (and other models) has a timing chain interval of 100k.

The Genny coupe engines from a decade ago seemed to require replacement between 70-100k. I also recall seeing mentions of 120k on the pre-G80 3.8.

Nowadays - the VVT engines can manage & take up the slack to a point - but if it gets too stretched even that will not be able to compensate. With that many miles on it - it might not be a bad idea to change it. However - unless the cold-start clatter lasts more than 10-25 seconds - it may still not be needed yet. The gamble is that it is an interference engine and if it does eventually slip - you are looking at a top-half rebuild with lots of new parts, at least.

The thing is, I don't have any clatter yet.

I bought my 2009 Genesis used in 2019 and it had 84,000 miles on the engine. I had it one year and had to replace the timing chain. I believe the mileage was around 108,000. I have had constant issues with the engine light over the past four years, and the code reader either brings up correlation issues between the camshaft and crankshaft sensors and/or timing issue code. So far we have spent almost $4,000 in parts and repairs to replace sensors and timing chain over the past 5 years that I have had the car. I believe we finally have the sensors fixed as they were replaced last october. The most recent timing code came up again this past Monday.

Can anyone tell me if the tensioners need replaced? These are the only items that have not been replaced. When I bought my timing kit the tensioners in the kit and the sensors were bad, so the station cleaned up and put both original items back on the car. Three years later we replaced the sensors.

Yes they do. They are plastic guides and they wear over time. Their springs or actuators may need replacement as well - if they fail to move the guides it will generate timing issues, even if you have a brand new chain and sprockets on your cams.

I'm currently looking to replace the entire front suspension in my 2010 genesis 4.6. Have you done it yet and if so what brand did you go with?

This thread is about engine timing chain changes, not driving gear suspensions. Maybe start a new thread so forum members can help you. There are some very smart people on this website.

Some were oem and some trq.
