I'm feeling a little defeated right now. I have a lifted 2006 XLT w/ 4.0L that I bought 10 years ago. Love this truck. A couple years ago my front brake caliper ate a grenade and I parked it in my shop for a rainy day project.
Well that rainy day came and I bought a bunch of parts to fix the brakes and several other things I've been wanting to do. One of those parts was a new oil pan & gasket. This is the first time I've had this pan off on this truck.
Well low and behold there was a piece of plastic in the bottom of the pan. I have not yet fingered around the upper oil pan to see if there is any more plastic parts. But it is pretty obvious to me that it is a chunk of timing chain tensioner.
I circled the part of tensioner I think this piece is. I do not remember a rattling noise when I parked this truck. I currently have half the motor apart in the truck to replace a bunch of broken parts.
I need to drive 2400 miles soon and was planning to take my truck, and now I am afraid to. Last thing I need tis to have my engine grenade half way through the trip. I don't have time to pull the engine and replace tensioners.
My question is: if this is the only piece of tensioner broken, how much of a risk is it to take it on a long trip? If I pulled my valve covers, would I be able to see the rest of the tensioners to assess over all condition?
well to start, That is not the tensioner. That a piece of the plastic guide/cassette. The 4.0L has three timing chains, two in the front of the block and one at the rear. There are also two timing tensioners hydraulic bolts as well.
Those tensioner bolts are oil feed and keep tension on the plastic guides to keep the chain tight. Those should be replace around 80k miles.

so is it not a problem to have that broken plastic guide in the engine? I’ll check out that link, I know the tensioner bolts have not been replaced yet. The truck has 130k miles. Engine ran fine as I remember when I parked it. I’m trying to assess if I can drive it another 5000 miles with that broken plastic guide. Or if that is a big no
