Keep your oil changed. Those pushrod engine chains are a lot shorter and stouter than these newer chains on the OHC engines. Nowhere near as much stretch to be had as long as you’ve got oil lubing and cooling them off. Ford wasn’t prescribing water (5w-20) back then.
I've heard of folks running oil from 5w-20 to 10w-40 on this engine... any insight?

With CLAssic Oldsmobiles/Ponitacs it around 80,000.
Is you father-in-law's 94 F-150 a 300 six? Or a 5.0/5.8 job?
About 10 years ago I was hearing with the 9th generation trucks it was aobut 90,000 miles for a timing gear change.
My suggestion is to replace the unit with a steel !

Epic first post. Calling out an 11 year old post as though they were wrong……

Replace motor or timing chain
I have a 2005 f150 5.4 with 375,000 miles on it. No troubles. The timing chain is tapping bad and needs to replaced according to my trusted mechanic. He says I need to run it until it quits and just replace the motor because of the mileage and cost. I’m keeping the truck. A new motor ford motor is 4500 plus labor to install. A new timing chain is around 1000 plus labor to install. Any suggestions

Calculate how many more miles you want out of the repair. You might get another 50,000 for the $1000 repair. Another 350,000 for the $4500 repair. Those are just guesses. One way to think about it.
Seems like your mechanic would have been suggesting the timing chain. Maybe he's expecting that the job will be end up bigger than the initial estimate.

if i were in your situation, I’d do everything I could to prolong life if existing motor, then either sell truck as is and move on, OR get s reman from reputable source. Good luck.
