Ford 4.6 2V Timing Chain And Guide Replacement.

On this episode I show you how to replace the timing chains, timing chain guides, and tensioners. As well as how to set up the timing on your 4.6 liter 2 valve Ford engine. Accessing the timing chain components is much harder than actually changing the parts. The procedure itself is basically aligning specific links on the chain with the marks on the sprockets.
Here are some of the parts and tools I used for this job:
Crank holding tool: amzn.to/2SwFMP6
Cam Holding tool (2 required): amzn.to/2SB0BZV
Cam follower removal tool: amzn.to/2XVPe4F
DOUBLE CHECK THE FITMENT ON THE PARTS! There are too many different timing sets for me to list all of them. If your vehicle has plastic tensioners I would suggest upgrading to the iron version. They have proven to be more durable.

[@JDMGoSpeedRacer]

So did you go with the plastic guide kit or metal guide kit?

[@t.farris1755]

Repair Geek sorry for asking a lot of questions but this is my first time doing this and I just want to make sure I’m doing it correctly so I don’t damage the engine

[@SANCHEZFLA863]

Hey Geek i know I can use the iron tensioner's on a 2004 crown Victoria @ list I think I can.. does the cloyes kit come with the metal gasket for the tensioner's do I need to use them or can I use the tensioner's on the crown Victoria the same way you used it on your mustang with out the plate/metal gasket? Or are the metal gasket only used in other applications? Also my car came from factory with the plastic tensioner's

[@BlueOvalEdge]

Well done. The tensioners have a fail safe feature that physically limits the amount of non tension so as to avoid piston to valve issues with momentary lack of oil pressure.

[@2RCPRODUCTIONS]

Cool vid man! I did this for the first time a few years ago with stage 2 cams with all new components with success. I didn’t lock cams or crank I just made sure all pistons were below deck by inserting a rod in each cylinder to double check piston height, might not be common way but worked great and put my mind at ease. It’s definitely a nerve racking process for the first time especially adding aftermarket cams. I changed oil pump so i needed to prime and I turned over to prime whole system before starting as well. There is definitely a chance for chain to jump a tooth on startup without being primed and without you knowing.Thumbs up👍!

[@justin.c_svt]

Great job man. I have done this years ago on my bullitt. I have to give you major credit. I see others making videos of doing it the wrong way. You did it right.

[@RepairGeek]

Thanks love the channel.

[@My68Tempest]

Been putting that off for a year because of lack of good instructions. You have made it look easy. Thanks

[@freddyhollingsworth5945]

Removing all 8 spark plugs will aid in the reduction of forces, including residual combustion chamber compressed gasses pressing down on the piston, and this can held reduce the hazard of bending valves. I'm glad you used metal tensioners as the plastic ones get weak and the spring gets weak and after 6-7 years of heat cycles and allow for super loose chains on start up and the loose chain on the driver's side will eventually bust the left side chain guide. The metal tensioners have that little ratcheting arm that presses up and keep the chains tight by keeping the tensioner arm pushed up tight in the absence of oil pressure. Great video.

[@_BAD_MERC_]

Outstanding and concise video. I get a little bit of a rattle if I don't drive my Lincoln Town Car for a day or two. I'd rather do it now than later. Thank you for leaving out all the stupid details. There's a good chance that if anybody is doing this, they don't need a close up of the 8mm socket you're using to undo the airbox. There's a pretty good chance they don't need that knowledge nugget. Your information was detailed and valuable.

@@281cu6 It wasn't that bad. The only real pain is the passenger valve cover, which is a really tight fit in the back. It is just a matter of patiently disconnecting the wires around the cover and then working the cover off. And of course, the rear of the cover leaked when reassembled so I had to remove it and do it again. But the second try I had a helper hold the wire harnesses and hoses out of the way while I shimmied the cover back on. I did it over two half days, but can easily be done in a day. The chains and the guides themselves go on very easily.

Thank you sir

[@TheUltimateCrash1990]

You can't just pull the pins, sometimes there will be slack opposite of the tensioner side on the chain( I meant that the chain touching the tensioner will be tight, but there may be "slack" on the opposite chain side if the cams are not in the correct time). If I remember right the LH camshaft sprocket is 12 o'clock and the RH at 11. There being slack opposite of the tensioner side means that timing is slightly off. Your method about removing the roller followers prior to messing with the chains was correct, good advice there. Also I think that cam holding tool you were using (T96T-6256-B) is only meant to be used on Windsor engines, I have a Romeo 4.6 2v and had to use (T92P-6256-A) and (T91P-6256-A). I love these engines, not a fan of the 3v. The HV Melling oil pump is def a must on the 3V's, I hate the new style plastic tensioners and cam phasers (too many issues)

hey man long time subscriber here - love your work. Today I ran into an issue doing this job on my 2011 Crown Victoria Police Interceptor. I've asked about 100 people online and everyone is telling me something different, so I thought I'd ask the expert directly. I replaced the chains, guides and tensioners with Melling parts. The driver's side chain lined up perfectly dot-to-dot. The passenger side is off 1 link. Would you suggest I remove the cam holding tool & turn the cam sprocket with a wrench slightly to get the chain to line up? Some are telling me this is perfectly fine to do, and others are saying not to do it - and if it's not lining up then something is wrong. I would really appreciate your input. Thank you sir

[@JerryHolaway]

I just bought a 01 f150 with a 4.6 and my local mechanic says I have a blocked oil passage and it is making my timing chain wear out due to the computer retard my timing and as a result the chain is making a slapping noise. His suggestion is to get a new motor and not mess with the timing chain due to the blocked oil passage.

Hi Repair Geek, Thank you for your reply. I did check a cylinder on each side of the 4.6, and both had compression. I believe that would show that the chains are not broken. Originally the timing chains were making a lot of noise. Took my 2000 expedition to a shop, and the guy there said to quit driving, and replace the timing chains... I let the expedition sit for 6 months, then tried starting... First engine turned over normal, then had a different lighter sound while trying to start. I can get the engine to fire intermittently, (kind of bumps around), but won't come close to starting. What do you think I should check now? Thank you for your help, and suport!!!

Do you have to take the tension off the chain when swapping out cams? Or can you just pull the old ones off and drop new ones In?

Question for you. Got a 4.6, was running but the rocker arms fall in the valve cover, so the gear on passenger side turn loose, how do I know were to put back the gear? Got new rocker arms and timing kit to install in it. Got the cam remove, scope the cylinder and everything looks ok. Thanks.

[@kamijoon4788]

Great Video. But, I would pre lube the chains and gears with assembly lube.

[@Shanaigins]

Nice video I would add a few things. first when installing new chains I would have at least pre soaked them in engine oil. I use a ultrasonic cleaner with my chains and oil to make sure oil the chain is properly pre lubed. second when building up oil pressure you just need to turn the key to the on position then hold the gas pedal to the floor then crank the engine over a few times like you mentioned until the oil pressure light goes out then release the gas pedal and the car will start. I do this every time I start my car after a oil change or if it has sat for any length of time.

[@RepairGeek]

The tensioners have oil sprayers that spray on the chains. If you pre-lube the engine, oil should spray on the chains as well. There is no harm in soaking them either. Thanks for watching.

[@matthewcrews4034]

Can someone answer what new valve cover seals he used brand names and what other gaskets used

[@silicon212]

I don't like the cast iron tensioners and the only reason is the ratcheting mechanism. It causes the guides to wear through in many cases, since tension can't let up. The newer plastic style has its issues with seal blowing, but they don't chew up the tensioning guides the way the cast iron ones do.

[@seanmathis8431]

Hi RepairGeek, appreciate all your videos they have been a big help. Currently going through this process however its a bit more complicated hope you can offer some advice. I had to replace my heads due to a valve isssue. My question is where should the crank keyway be positioned when reinstalling heads? I have a bunch of people telling me that having the engine at TDC is incorrect for a head install, they say to put the keyway around 9 o clock position for PTV clearance, which makes sense however, im confused how to get the timing chains lined up with the markings on the crank and cam gears at that point?

[@RepairGeek]

If you're concerned this is how I would do it: 1. Pull the cam followers out of the heads. This way it's impossible for any valve to be open. 2. Install the heads with the cams in place, time the motor as shown here. 3. Once the cam timing has been verified to be correct. Reinstall the cam followers using the cam follower removal/installation tool. If the cam followers are not installed in the heads. It's literally impossible to run a valve into a piston.

Have a Crown Vic 4.6 …Instead of using a cam holder or removing followers I used vise grips… hindsight is 2020… that being said when I reinstalled everything my passenger side chains is loose (along the guide)…should it be tight? Because I have read Ford engines rely in oil pressure for timing tension?? Any info helps thanks!

with the chains off, would the cams move when the holding tools are removed? Would this even matter if replacing cams too?
