Missing one head stud for my TIV. Can i use the Type 1 head studs? I have several used Type 1 cases lying around.
I'm guessing its not a good idea to just replace the one head stud since the Type 1 head studs are much thicker and could have a different expansion rate? What if i replaced them all? |

The head stud designs are critical. Randomly swapping out studs that kinda look alike but are different diameter, different length and possibly different material is a no-no. Kinda like trying different size bullets in a gun to see if they will work. The studs are carefully designed to apply a certain force on the head for the torque on the nut. The idea is to hold the head in place with enough torque so the head doesn't move away from the cylinder when the engine fires. Stud stretch is carefully designed in, and the expansion and contraction due to temperature plays a part in the design of the stud and the torque. Different diameter, different length or different material will make the odd stud behave unlike the others. |
