Broke intake manifold bolt - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

IndeedSS1 · 03-10-2012, 04:15 PM

I was doing the fuel line relocation mod today. All was going well until torqueing the intake manifold bolts. For some reason my torque wrench stopped clicking on the second bolt from the back on the drivers side

. And about the time I realized something was wrong the bolt snapped.

The car is idling fine but haven't taken it out for a drive yet. What are the chances I can run without that bolt and not have problems?

Personally I wouldn't risk it. But it depends on which bolt it is. If it is an end bolt chances are worse than if a center bolt which has bolts on either side supplying some torque holding value.

Just go get another bolt. And chances are you over torqued some of the other bolts.

Thanks guys.

I'm not sure why it was that one bolt but the rest torqued fine. A local builder said since it wasn't an end bolt it would likely be fine. The car idlles and drive fine and the fuel trims look good. I am going to spray some carb cleaner around that area while the engine is running to check for any leaks. Fingers crossed. Even if it's good, eventually the bolt will be replaced.

Take the time to fix it, the intake manifold is plastic, in time it will leak, do it next week and get all new bolts you dont know that there torqued right.

What is connected to the back of the intake manifold? I wanted to remove it too, just out of curiousity, but something was connected that i couldn't see.

True, unless the bolt was defective to begin with.

Wow old thread. I put 50k on my car since the discussion and sold it.

black79ta · 05-19-2013, 10:24 AM

Just curious, did you ever fix the bolt, or did it run fine for another 50 k miles?

My SS was a daily driver that sometimes made multi-state trips so I was too paranoid to run without an end bolt. Chad Barton (CBI) was able to extract the recessed end of the bolt. He basically was able to weld enough tiny beads on top of each other until it was high enough to weld the top on and then back out the entire thing and install a new one. It was pretty impressive to me because it was recessed in the head enough that I wouldn't have thought it possible.
