Intake Manifold Bolt Removal??
I have a '72 C-10 350 with 250k + miles on it. The engine is all stock/original...never been rebuilt or even apart to my knowledge.
When I replace my water pump in the next couple weeks, I would also like to remove the smog pump and the bracket to which it is mounted. This bracket is mounted to the block in 3 places: water pump bolt, and two bolts on the intake manifold. Here's my question: Is it reasonable for me to think that if I loosen ALL intake manifold bolts in the reverse order from torque pattern (each a little at a time), remove the smog pump bracket, then retorque all bolts in sequence, that no harm would be done? I want the smog bracket gone, but not at the expence of having to actually pull the intake manifold to clean and reseal etc, etc... And how about those two manifold bolts, do you think they are longer than the others and would bottom out before tightening with the bracket removed? Thanks for your thoughts/suggestions...would you or would you not? |

Re: Intake Manifold Bolt Removal??
Don't worry about the order of the intake bolts. The order really only applies to when first installing the intake. Just worry about having the correct torque AND using more sealant on the bolts to avoid leaks. If you take the bolts and and compare the depth of the bolt hole to the length of the bolt, it should be apparent if the bolt will be too long.

Re: Intake Manifold Bolt Removal??
OK guys, thanks for the input.
On that sealer, could I just use the same rtv I'm planning for the water pump replacement? or is there a different one I should consider? And I imagine the sealer is more important at the head and top of the bolt not at the threads right? |

Re: Intake Manifold Bolt Removal??
Be careful taking them out though, one of mine snapped. Hit em first with some kind of penetrator and then let sit then shock the top lightly with a hammer. I just went for the removal without doing any of that, snapped one off and then instant full intake manifold job.
