In some cases, these codes set because of the extra amount of slack that develops in the chain itself. These Triton V-8's are known for setting cam phaser codes from P0340 through P0349. In addition, to the knocking noise complaints as a result of incorrect tension or broken plastic guides, we can also set a fair amount of check engine light codes. You can also use the old large screwdriver carefully pushed up against the ear trick, but the mechanics stethoscope certainly works better and only cost around $20. Here's the best way to verify the engine noise you're hearing is from the timing chain. The plastic guides can break and the fragments will wind up in the engine oil pan. The engines often make a lot of noise at idle when hot or a rattling sound on cold engine startup.īoth of these issues point to problems with the tension on the chain and the condition of the guide assemblies. Many of the symptoms associated with a handful of the problems, turn into noisy operation complaints. We'll get into exactly what goes wrong with this particular set up on the Ford Triton engines in the next section. However, we can group a bunch of the symptoms together to help us understand if our complaints point to a timing issue. Each one of these failures carries a different set of symptoms. There are a bunch of separate things that can go wrong with the Ford Triton timing chain system. These malfunctioning cam phasers also set a variety of check engine light trouble codes. We'll even take a look at the cam phaser gears known for creating a knocking sound at idle. Join us as we dive into first design problems with the plastic chain guides and tensioners. Note: The 2005 - 2013 Triton 4.6L uses a different part number kit than the 5.4L equipped trucks. Here we'll talk about the common symptoms of the Ford Triton timing chain problem. Unfortunately, this power plant provides many challenges for owners and drivers. It's hard to say it's a good engine, but it's undeniable they can go a long way when cared for properly. From 2004 through 2010 this engine came inside one of the best selling trucks of all time, the F150. If you think for a moment, about how many engines we're talking about, it's mind blowing. This truck motor launched in 2004 and ran through 2010 in the 5.4 L displacement. The engine is the 5.4L 3 valve per cylinder Triton engine. The OEM updated kit directly below fits 2004-2010 F-150, F-2-2013 Expedition and Navigator. However, my point is, this remains a time consuming operation that you don't want to do twice. I've included one of these bargain kits at the bottom of this page that has decent reviews. When sourcing parts I recommend OEM replacement kits.įortunately, I have gotten away with much cheaper after market kits without a problem. With that said, here we'll focus on the timing chain problem. Although I've seen the Ford Triton V-8 with 300,000 miles on it, these three valve V-8 engines haven't been exactly trouble-free. The Ford Triton timing chain is a complex set up featuring two separate chains.
