FORD EXPLODER REPLACING TIMING CHAINS PART 1

In today's video, I take you through my journey of replacing the timing chains on my 2008 Ford Explorer with a 4.0l V6 SOHC engine. This job is very labor intensive, time consuming and must be done properly. I wouldn't attempt this job if you do not already have experience working on engines. If you have not watched the last video I posted with this truck, please click the link below to watch! In that video we tore the engine apart to discover the source of the loud engine rattle, which turned out to be failed timing chains, guides and tensioners. In today's video we replace all of those broken components!

The mechanic changing my timing chains on my 2006 could not get this job done and had my truck for 4 months. Had to get it to a second mechanic that was able to get it running but there's still a light rattle and oil is leaking from the pan. I changed the lower gasket but it's actually the upper. If I have to lift the engine to change that gasket, as shown in this video, I think I'm going to junk it soon. This repair has been a nightmare, especially because I take care of my vehicle and am going to hate seeing it go. Wish I found someone as knowledgeable as you. Great video.

[@kinglangren]

Bought one from my neighbor for 500 a few years ago with the same issue . Decided against fixing it . Posted it for sale and I had almost a 100 people message me, so they are still a popular vehicle. I’m with you if it was now I would have fixed it as it would be worth it.

[@AKJeeper]

Yup - I would have elected to fix it as well. Vehicle prices are insane right now, and being that it's a southern rig, it's in beautiful rust-free shape. I'm sure someone would buy it in the event Eric didn't want to keep it. Too bad it's not a 4x4, a rust-free 4x4 Explorer would sell like crazy up here!

You can prime the oil in the tensioner by holding the gas pedal and cranking with it depressed, it will not actually crank but will move the oil into the tensioner from the starter cranking.

[@C0Y0TE5]

As ford recommends

[@tomh6779]

That engine was not one of ford’s better idea’s. They tried saving money by re engineering an old school 4.0 liter to a modern variable timing engine. It made good power with a little bit better MPG. Serviceability not so much lol. Great job and thanks for posting.

[@HUBBABUBBADOOPYDOOP]

Are you old enough to remember the Jetsons? There were 2 major competing companies. Spacely Sprockets & Coswell Cogs. Your timing chain is driven with *_sprockets_* and a timing belt is driven by *_cogs_.* Most diesel engines use gears for crank to cam to fuel pump, and some inline 6 cylinder use gears. My '71 Nova had an inline 250ci, and used gears.

[@gflores7018]

Welcome back Eric Good luck on this job, definitely not a easy job.

[@juanchavez2231]

[@HatBilly2008]

Saving your 4,0, engine. The early warning signs of timing chain issues on the 4.0L are almost always ignored. Yes, the timing system is very flawed in design, but there are steps that you can take to prolong the life of the timing system and engine. The first part in this timing system that gives is the chain tensioners, which leads to broken guides and eventual failure. As the poorly designed tensioners age, they become weaker (as we saw in the video) and cannot hold down the guides to keep adequate pressure on the chains. This is especially true on cold starts because oil does not reach the tensioners immediately, which allows the timing chain to slack and bang off the plastic guides, creating the characteristic 4.0L "startup rattle". After many cycles of this, the guides break and the rattle becomes constant while running/under acceleration until enough of the guide material is broken and the timing jumps--leading to an often catastrophic failure as these are interference engines. This can be prevented, or at least prolonged, by replacing the chain tensioners every 50-70,000 miles with new OEM units (Ford still makes them and they are cheap); they're outside the engine as seen in the video and easy enough to replace that a DIY'er can do it. Another issue that isn't spoken about nearly enough is the use of improper oil filters on these engines. These motors NEED oil filters with anti-drainback valves (OEM Motorcraft FL820S or equivalent) to help against oil starvation on startup to the chain tensioners--this alone will help prolong the lifespan of the timing system in these motors; the same ironically applies to the 4.6L SOHC V8 which can suffer from similar timing issues. Both the tensioners and oil filter are cheap insurance that almost anyone with minimal mechanical knowledge can do in their driveway. It's not uncommon to see these reach very high mileage, even while rattling around on broken chain guides--they're actually quite durable motors. Notably, the original nylon chain guides on this engine from 97-01/02 97-01/02 were deemed to be too weak by Ford, and the timing components were revised. Later models do fare better, however, all of these engines will eventually run into timing issues unfortunately as the design is just inherently flawed as a whole--the trick, again, is to catch it in time. The upside is that they made literally MILLIONS of these engines and parts are easily obtainable. I've owned and continue to work on a number of cars with this engine. By far the worst 4.OL timing failure l've personally seen so far was an 01 Ranger on original chains blow a hole straight through the driver side valve cover at around 260k.

[@mavricxx]

Honestly, if you need to do any timing chain, do it it right the first time and do them all. Don't cheap out cause it'll comeback and bite you in the ass. I've had this happen to me so many times but I'm not a professional mechanic, just a diy guy but I've learned so many lessons along the way.

[@williamwhite9767]

Man, I didn't know how easy I had it changing timing chains on the old small block chevys and once on a 73 Cougar Cleveland V8. Only one chain instead of four!!!! But they had to changed often due to the lack of chain tensioners and those nylon teeth breaking on the cam gear.

[@Garth2011]

Back then the upgrade was to buy Cloyes Double Roller Timing Chains and forget the OEM nylon idea that hurt so many.

[@robc7323]

Nice job! I did the timing on my 2005 Mountaineer-4.0 SOHC last summer at ~230K miles. It had the startup rattle + rattle at ~2500 RPM. I drove it for ~5 - 7k miles with the rattle before the repair and the timing was still good. The only tensioner that broke in my engine was the primary tensioner (leaf springs) between the crankshaft and jackshaft. It was sitting just below its original position just like in the video. I pulled the engine and did all of the guides/tensioners/chains/sprockets gaskets/front+rear main seals while I had it out. The compression was surprisingly good for an older engine so I did not mess with the heads/piston rings/etc. I am currently ~240k miles. If anyone wants to attempt this job, I suggest trying to use OEM parts... ford updated some of the guides/tensioners in later model years. Ford does not offer a kit so you have to compile a list and order a la carte (PITA). I heard some of the aftermarket parts can grenade prematurely so if you plan to keep your ride long term, take that into account. If you go aftermarket.. at least get Ford hydraulic tensioners. I have hear some bad things about the aftermarket ones not holding tension. The early model year Explorers ~2000 - 2003 were particularly prone to breaking timing chain guides. I have a 2005 and some of the parts I got from Ford were different color plastic so I assume that these are updated from the ones that were in my block. I got ~230k out of the original parts so I hope to get some decent mileage out of these. The 4.6/V8 guys are lucky since all of the timing components are up front.

[@94SexyStang]

yes but the 4.6 have a Horrible reputation of blowing spark plugs out of the engine, I've seen SO many engines running down the road on 7 cylinders......the v8 problem is WAY more common than the v6 timing chain issue.

[@LSmiata]

Great video! My opinion only....Ford went with a block design from the 70's or 80's that had cam in block, then decided to make it an OHC. You can clearly see the front of the engine and 1st timing chain going where the cam would be on a "cam in block". What a POS design. No wonder we get our ass kicked by Japan and newer Asian entries. They start with a clean paper and work it to modern standards. GRRRR FORD! Same thing with Ranger 3.0 and 4.0 engines. Use 50's tech to control spark from a distributor......and how about the oil "pressure" gauge. NOT it's a dummy light disguised as a meter.....GRRRR! I loved my 04 Explorer with 4.6 v8 in Eddie Bauer trim until it got totaled...grrrr...and right after, I'm talking days, that I replaced the rear axles seals and axle drive boots.....unlucky, but it was a NICE ride. Hate me but now back to GM or Toyota.

[@CrazyPetez]

What kind of misguided engineers designed this engine. It’s a nightmare of parts and building requirements. And I always thought Ford built good engines.

[@sumduma55]

It is likely so they can reuse casting with different engines and applications. For instance, having the windage tray separate from the block and oil pan would allow the use the same timing covers across v6 and v8 and possibly v4 platforms. You could also reuse a lot of the components between turbo and naturally aspirated versions. This can translate into less retooling and process swapping, and training meaning less downtime at the factory and a costs savings.
