Hi there,
Repeatedly breaking intake studs in the same cylinder is indicative of an underlying problem or issue. Here are the possible causes:
1. The stud quality. Most likely, you have encountered a batch of faulty manufactured studs. Ensure you have picked and selected a high-quality brand of studs.
2. Torque issues. Make sure it is not over-tightened. Follow the manufacturer's torque specifications
3. Misalignment. A possible rare problem is the intake manifold, or the heads might be slightly misaligned, causing stress on the stud.
4. Incorrect pushrod length. If the pushrods are too long or too short, it could result in improper geometry, leading to excessive stress on the valvetrain components, including the stud.
I hope those details gave you an idea of the possible causes of the problem you encountered. It should help you find the possible solutions. Still, consult a certified mechanic for thorough quality troubleshooting and repair if you have the budget.
