loose timing chain 2007 4liter SOHC Ranger
Got this bad news the other day. One technician said I have a bad tensioner, and got another opinion, and said that the timing chain guides were broken, and I need to replace engine. Motor has 187,000 miles on it. Not sure what to do. Anyone had this happen? I hate this, as I just re-did my suspension, lift and 31" tires, about 1 week before this happened.

Welcome to the forum
"Replace engine"?
2007 4.0l SOHC shouldn't have timing chain issues, 2004 and earlier did
But in any case you don't replace the engine.
If it is the rear timing cassette then yes you do need to pull out the engine.
But if it is one of the front cassettes/chains then it can be done with engine in the truck.
Cassette = timing chain and guides.
4X4 4.0l SOHC rangers also use a balancer shaft chain which 2WD's don't have, doesn't add much to cost to replace it as well.
Engines are usually good for 350-400k miles so worth fixing, and if you replace engine you still need to pull the old one out and reinstall the new one, so............
In and out cost is the same, to fix or replace engine.
And to fix the engine's timing chains will be less than used or new engine.
Used engine is a gamble, new engine maybe, but fix the old one when it is out and sell it to off-set new engine price.

Yeah, the problem was definitely fixed in 2007. I have a 2007 4.0 SOHC that has around 391,000 miles and is still running strong. A lot of it has to do with keeping the oil changed in these engines.
Now on the other hand I have a early 2004 4.0 SOHC and the RH rear tensioner failed on it and I'm now in the process replacing that after watching many YouTube videos.
You can get the Cloyes timing chain repair kit on Amazon for like $330 and it comes with everything you need except the 2 torque-to-yield bolts. A good used 2007 4.0 SOHC engine will cost you at least $1100 because they're pretty hard to find (and you really don't know how good the original tensioners are)
