will snug be enough?

 

thank you for your help!

 

Don't know. If not then you'll need to use a heli-coil.

 

thank you. I REALLY appreciate the help.

 

here are some pics of the bolt location. I'm not sure of the function of this part and if it would contribute to oil leakage.

 

 

Worst case, you have to helicoil the thread hole, which you should have done by a professional mechanic (requires drilling out the hole to a larger size, threading the hole and installing a helicoil insert). Is the upper camshaft assembly bolted to the head in your car and the above pics are taken from the internet? If so, access for a mechanic to do the helicoil repair might require him/her to remove the upper camshaft assembly to get access to the bolt hole. Yes, the bolt needs to be torqued to factory specs - the bolt is there for a reason. The threads won't magically fix themselves and adding something like JB Weld will only cause a future problem.
