Torquing intake bolts on 3.1 out of 95 cutlass Ciara cruiser
I have a husky digital torque wrench. I am trying to torque down some intake bolts on my car but the number seems to go up and down between 27-28 ft pounds while I’m trying to tighten the bolts. Can some explain this to me please?
also the book is saying to torque the intake bolts to 115 ft pounds, is that number really correct?

115 is not the correct number for the intake.

since the wrench is digital so it can be something like 27.23. Do you have any idea what can make a digital unit register 1 number than start to go down slighty instead of going higher since I’m still tightening the bolts?

My guess is the bolt it tightening up against friction and then unbinding a little. Not worth worrying about unless it didn't thread in nicely. This would never be noticed on a normal non-digital torque wrench.

You need to take the intake off and chase all the threads and make sure they are nice and clean and then install at 115 inch pounds. Mitchell shows.
