Repair Manual Question - Engine Torque Values

I work from a 1977 Chevrolet Light Duty Repair Manual. Every section shows a page for Specifications. These pages give torque values.

I cannot find torque values for the engine section. A page for Specifications are not shown in any of the 3 indexes (main, 6cyl, 8cyl). The last page of the engine section is Specifications for engine measurements, but no torque values are shown.

I am certain that it is reader error on my part, but can anyone guide me to where the torque values for engines are shown?

Thanks!

Sorry about it being sideways.

Re: Repair Manual Question - Engine Torque Values

Thank you for your help. I find it hard to read, and I am not at first able to print it in a form that I can read, but I will work on that.

Again, thanks!

Re: Repair Manual Question - Engine Torque Values

Thank you! That copy is readable, and the print screen is also. I added the page to my book.

I am tightening valve cover and oil pan bolts. I found somewhere on this forum 80 inch lbs for the 1/4 inch bolts and 165 inch lbs for the 5/16 inch bolts. I wanted to see what the book showed, but I cannot find those values in my book. I could not make myself get them that tight, so I chose 50 and 75. Those values are far tighter than I have ever gotten them.

So far, the puddling seems to have stopped.

Re: Repair Manual Question - Engine Torque Values

I’ve always gone by feel. Never got lucky trying to torque them.
What type of gasket?
Cork, cork/rubber, rubber etc are different kinds.

Cork. I always used to do the same. I never wanted to take a chance of mashing the gaskets or de-forming the sheet metal flanges, so I believe I was too easy on the tightening. I always had leaks. Now they are a lot tighter than I ever put them. I used the torque wrench to make sure that I tightened each one the same.
