I just brought home a 2011 Sport 4x4 with a blown head gasket. I bought this truck with the intentions of hacking it up for my diesel conversion project, but this truck is too nice, so it's getting put back together as Ford built it. This was my first time going through a 4 liter. I had both heads reworked and checked at the machine shop. During the rework, I replaced the timing chains and all of the gaskets. It would be silly to not do it while I'm in there.
I purchased a Cloyes timing set, with the balance shaft set. I was surprised when I removed the timing cover. There was no counterbalance shaft on the motor.

Something I was very surprised about during the build was the fact that the Cloyes kit did not come with new jackshaft bolts. They are one time use only, torque to yield bolts. I assumed they came in the kit. I didn't realize they weren't there until I went to time the engine. Napa, AutoZone, rock auto, no one but Ford has these bolts. So here is my question? Are people actually replacing these bolts, or are the old ones being reused? I'm betting no one is spending the $28 for one bolt from Ford. I'm not going to chance it myself.

While I haven't done work to this level on a 4.0 SOHC, I have worked on other engines. I have never reused torque-to-yield in any engine intended to run again. I agree with your inclination to do so. Especially with the amount of work required to get to where those bolts are. If one fails, it's not like you can just fix it where it sits and move on.

I personally would not reuse most bolts that are torque to yield. When I did the tensioners and guides on my Grand Marquis, I got a new bolt for the crankshaft pulley. It was not worth the risk. When I did brakes on my mother's Jeep Cherokee KL (new one, not the classic XJ), the caliper bolts were torque to yield. I purchased new ones from the dealer, and had to wait a couple days because they did not have them in stock. The parts guy said to me, "Well, you really don't have to replace them, we don't when we do brake jobs."

The only time I did reuse bolts was when I removed the bed of my pickup. I believe they were designed to be replaced. However, with the price they got for the bolts at that time, times 10, since ford decided the Ranger needed 10 bolts for the bed, I held off. The bed is different than the engine, brakes, drivetrain, etc.
