Torque Specification Confusion
I'm in the process of reinstalling the valve cover and push rod inspection cover on my 81 F100 with a 4.9 six so I was searching for the torque specs. I'm pretty sure the information on the valve cover is correct which says 4 to 7 ft lbs (48-84 inch-lbs). But I found 2 different opinions on the site for the inspection cover. One says 2.8 to 3.9 ft lbs (25-35 inch lbs). The other says 1.5 to 2.2 ft lbs (18 to 27 in-lbs) Can someone chime in with the correct specs for both covers? Thanks.

Who uses a TQ wrench for valve, side cover and pan bolts?
Stubby 1/4 drive ratch is all you need as you cant over tighten with that but get it tight enough.
I dont own a inch pound and my TQ wrench think starts at 50 lb way to much for them little bolts.

Does the gasket supplier recommend a torque? Often different gasket types need different torques. And maybe a tightening pattern as well? You can estimate torque for example 5 ft-lbs is 5 pounds force on a 1 foot long wrench or ratchet. Or 10 pounds force on a 6" tool.

Just remember you’re tightening a small fastener. Not trying to break it off. There are very few things I torque.
I’ve been working on things for over 60 years.

Agree, I know the difference between inch lbs and foot lbs, so I don’t want to over tighten or under tighten either cover, that's why I'm trying to find out the proper torque specs.
