so im installing my new cam, and i was told to be very careful to torque down the cam retainer plate, and while doing so it stripped the threads in the block on the very top bolt. the other three are in solid. what can i do to fix this? i dont want an oil pressure problem. thanks

 

small bolt = low torque value!

 

Helicoil time!
The kit will run you near $100.

 

If the hole is blind, use a helicoil kit. Autozone has them for around $20.
