Ford recommends replacement of the tensioners every 75,000mi.

I just replaced mine—probably closer to 120,000mi (oops) and the difference in startup clatter was pretty dramatic. I think @donalds recently cut open an old hydraulic tensioner and found that it has rubber seals in it that may dry out. The spring also weakens over time, and this is what keeps things somewhat under control until oil pressure builds.

I can say with authority that the truck sounded better on both cold and warm start without pre-cranking to prime the system. The old tensioners were clearly shot, and I wouldn’t consider them a ‘lifetime’ component. I should’ve done mine closer to 75k.

I still crank mine to develop pressure on cold start.

Manual tensioners are next for me.
But have you never wondered why there’s no mention in Hayne‘s Repair manual of a how to do a tensioner service?!
Or did they know that is a risky subject :)

i have a Chiltons and it’s about as worthless

Hehe…Most of the times i actually like the Haynes a lot. It’s even a bit too elaborated sometimes. But i found it odd, that they didnt even mention the tensioners.
 






Can't you buy the factory service manual on CD for about the same money as the manuals above??

Super awesome! Thanks so much for the link 👍👍👍👍 after reading it 5 minutes, it already answered 3 questions I had. Cool stuff
 






I have the 5000+ page FSM on pdf format, but sometimes it’s good to have the greasy fingerprint covered crap manual on hand for the quick reference easy stuff

Definitely
 






I guess at this point I am going to try this weekend to do the checks that fbird pointed out to see if I can rule those out first.

Can you get a good enough visual of the condition of the guides by removing the valve covers and bottom oil pan? Can you tell if the part the tensioner pushes on is broken? That would be the next logical step to determine what to do next?
 






Peek in the oil cap... you can see the top of the plastic guides...

Oil cap only front. And also just a peek. Cant whiggle/inspect it to check the guides and the tightness of chains out.
Lower oil pan just if there are small broken pieces. If there is nothing in the pan, it doesn’t tell you anything really. Guides could still be broken.
But removing the valve covers takes a while. It’s not as easy as it looks in some videos. A lot of stuff to remove.
I’ve invested a few hours already and only just removed the passenger side cover.

When mine blew finally at 250k my rear and front both were just chains. That’s it. The crank to Jack had worn all guides off and the chain actually broke from wearing on the block. The tensioner for the balance was destroyed too but chain still stayed on. I got lucky it blew no throttle. Barely tapped two pistons with valves leaving NO damage. The couple times Ive seen timing components go they always seem to sit inside timing cover and don’t drop except tiny pieces. May be able to get a small inspection cam Down in there to check. Super cheap off Amazon especially if you use a laptop for the screen. Timing set, gasket, and sensors and I’m dogging most my friends with v8s after my rebuild. The WOT start isn’t a trick, it’s a recommendation for BEFORE you u start it after it sits. This is very true after a couple days however most damage in occurs in freezing temps. Plastic rips instead of slides at low temps, doing the WOT start in cold weather and letting this truck decide when to drop idle bc it’s warm enough before driving off a is the trick to a long lasting timing assembly ( assuming oil IS actually changed regularly #1)
 






Did a little testing and driving. Started by looking in the oil cap area and the tensioner and guide piece looked normal. The chain and upper sprocket look good with now major signs of wear or rubbing. Started it up the wot method and looked back in the cap, everything normal sounding. Decided to drive it and try the torque converter test. As I am pulling out onto the road I notice that its not making any noise, as I accelerate up the hill its not making any noise. Before it was noisy on acceleration up the hill. drive it 4-5 miles accelerating and decelerating and its quiet, no noise. Pull off into a unbuilt neighborhood and stop and listen to it, no noises. Stepped on the brake and accelerate with both the OD on and off and no difference. Get back on the road and then I can hear the rattling on acceleration but much quieter than before. Once its up to 40+ mph it doesn't happen anymore. All this was done with the a/c off as the compressor is going bad and making its own noise. It was off before when I was testing it to. So its been sitting all week undriven, and its been cold, But its already warmed up into the 70's now, but the engine would have been in the 40-50's when I started it.

Also the other odd thing is I can't get any codes out of it. All I get is the P1000 code. Its been a while since I have erased any codes or disconnected the battery.
 






Finally had time to watch all 4 parts of the videos that was linked. Lots of good information and visual explanation of whats involved. Even if its not the problem, I feel like its time to either repair it or sell it. I have spent a lot of time keeping it going over the years and would like to keep it as my daily driver and work truck, but I am always worried if today is the day that it blows. So I am going to start to look at parts needed and tools and decide what my next step is. If I do decide to tear it apart I dont want it to turn into some long project, so hopefully I can put a good plan together and order the stuff I need ahead of time. I am going to start another thread about available parts and quality issues. Looking for some feedback from others on what brands or non brands of parts they have used and any issues so I can figure out what to order. Still want to try and stay around $500 but I think its going to be more than that. If it looks like its getting closer to $1k that might be the decision maker.
 






My other consideration is just doing it on the cheap. Only replace the plastic guide parts and use the manual adjusters. Reuse the chains and sprockets, skip the water pump unless it really feels bad and reuse most of everything else.

Dont know man, I wouldn’t cheap out on parts, as the main labor of removing the engine is the actual tough and resource consuming part and for your car (probably?) a once in a car-lifetime happening. I posted a recent buying option on your new thread. If i had the time and resources I’d buy it. Sounds like an extremely sweet deal. I know in Germany all these parts will cost me around 800€.
 






Just wondering out loud. Its old and high mileage and I dont want to dump a lot of money in it. Guess I wouldnt know the condition of the chains and sprockets until I tear it down. There are so many kits that come with almost everything for about the same price as the guides themselves.

I ran across this statement on the Melling kit on rock auto. "Engines w/ Balance Shaft; Due To Numerous Changes To This Engine The Front; Jackshaft, Crankshaft and Balance Shaft Sprockets Must Be Updated To The Latest OE Design. There Is A 2mm Shift In Centerline; Timing System Failure Will Result If Original Sprockets Are Re-used" I havent run across this information any where else. Some of the kits dont include all the sprockets. Guessing that since mine is the first year I should use a kit with all the sprockets?

I used the cloyes kit. It seemed like a solid set up. I like them more than Ford for older products simply due to the number of timing kits they make IMO compared to Ford who shelves them for longer.... I would assume. All this is speculation. With that said. I would go with no other set then NEW FORD/CLOYES as this IS the most important part of this motor. I’d reuse head bolts before I cheaper anywhere with the timing. Cloyes does just fine anything I’ve put them in. High horses to long running jeeps. This is also the only motor I see ALWAYS snap a chain before a no start situation from timing components. Many vehicles just stop one day. These motors go boom. My motor was a 97 built sohc and yes the sprockets were changed when I redid my motor. But I believe it’s only one of the balance shaft sprockets that gets changed. Maybe my memory is off. If you have changed oil regularly these lower ends especially were designed 400k plus reliability and the top end normally just needs to be disassembled with timing components as needed and it holds that 400k mark too. The only part that WILL fail before that mark inside the motor is the timing assembly. That’s what gets such nice power from such a small box. Always a give and take. So if it’s half the price. Expect less than half the quality. Which will relate to far less than half the lifespan of the part. Again in this case.... the one thing NOT to cheap out on. Many people blast me using cloyes and not Ford and that may be true, however the quality argument is quite different with any other “economical” option I’ve seen.
