4.0 SOHC timing chain - how troublesome?

[swampyankee]

I've been looking high and low for a replace for my '01 Ranger. I'm just now reading about the 4.0 SOHC, and the timing chain tensioner issues. I've owned my 01 with 4.0 SOHC for about 8 years, but only 50,000 miles and the only reason to replace is that it's badly rotted out.
Should I approach the early SOHC's with caution, avoid certain years, or stick with older pushrod motors?

I think the chain issues were resolved around 05.

So basically 05+ or stick with a pushrod if you want to avoid trouble.

Im sure someone more familiar will chime in

Find a decent 01 and put your engine/transmission in it.

Mostly a non issue at this point. Most of the trucks with tensioner issues have either failed or had the tensioners changed.

The tensioners should be changed every 70Kmiles. Just a maintenance point. Takes about an hour, maybe less if you've done it before. You do it when you change the oil.


If you buy a truck with a SOHC, just change the tensioners. When you buy a used vehicle you should follow up on maintenance things anyway. Change the oil, filters, plugs, ect.
