So over a year ago, replaced front and rear timing chains and tensioners in my 98' Explorer. Learned a lot during the process, including how lucky I am to still have fingers. (If anyone is curious, I can go into detail later). She's been running great for about 15,000 miles and then, after leaving work one day, the engine stalled on service road. Through tons of troubleshooting and trying to deny the horrible pit in my stomach, it turns out one of the cams jumped time. How exactly? Not sure until I get the heads pulled off, but I took a scope to cylinder #6 and saw this:
That's on the driver's side of the engine.
Here's the passenger side cylinder #2 :
I've got my fingers crossed that only the driver's-side cam slipped and that the the rear cam and jackshaft have stayed with crank. If that's the case, I can do the valve replacement without removing the entire engine.
