External timing tensioners on the 4.0

[Fix4Dirt]

Yep that wiring is almost as bad as the Mercedes with biodegradable harnesses

gm had soy based ones iirc. those got eaten up by mice!

 

[Fix4Dirt]

I was thinking if I still had the issues with shifting after I get the harness all patched up I would rebuild the valve body and install a shift kit.

usually a shift kit can help the 2-3 flare

Thanks for your help guys, I’ve done a lot of repair but not so much with engines. So this is my first rodeo with pulling one of these suckers apart. So all of your advice is welcome and much appreciated!

Hey fellas
I made a video a while back
A little more info I feel like I specialize in stopping start up rattle
Here's how it works old oil clogs the timing chain tensioners
Which causes the chain to slap timing guides
then They break and you have problems depending on how much they break. Ford Timing Chain Tensioner Cutaway

^^^yep donald is another good resource on sohc same with 410fortune as well. have you noticed any difference in the sohc tensioners too?

 

[donalds]

have you noticed any difference in the sohc tensioners too

I installed 2 Manual tensioners on the 2004 explorer
Haven't really messed with it since
You really need to understanding on how the Timing system works in order to use the manual tensioners I tried to leave good instructions but there's nothing like experience

2010 mountaineer 4.0. 86,000 miles. Change oil every 3,000 miles. Looking down the oil fill cap head is spotless. Still has the original tensioners. Mountaineer can sit 3 months in winter and when started there is no noise. That brings up the question should I change them or wait until I hear the noise.

Wait until you hear the noise that is what I did

Agree thank you

 

[Lee's Automotive]

Agree thank you

Your Welcome

 

[Flashflood]

agreed. do keep in mind the HV pump will not help the tensioners in that iirc oil will not reach the top faster, as it reaches quite quickly. its a myth that it will run the pan dry in nearly every circumstance, but it will increase pressure too, so that could have effects as well. all depends on what you are doing with it.

I got quick question for you guys @Fix4Dirt and @Lee's Automotive when you guys did your timing chains did you keep the engine in the vehicle or no. I've been trying to install the tensioner on mine and that's been a pain in the butt

if its the front primary chain it can be done in the rig. any pics of the situation? dont recall changing the tensioner itself a pain

 

[Fix4Dirt]

is this the part you are looking at?

If you have to do the rear chain the engine has to come out

 

[Fix4Dirt]

yep depends on which chain

 

[Flashflood]

yep depends on which chain

Well I honestly think it's the front one making noise on Start up even if I prelub it's still a grump on cold days
