Removal of manifold bolt - Drilled in too far

[Toolbox1]

Hi Folks. 

I purchased a stomski SR067 jig recently to remove the sheared exhaust bolts on my Porsche 996. 

I find the kit very good and have most of the 12 sheared bolts removed at this stage. 

However, due to no fault of the jig, I managed to drill in too far on one bolt. 

I had the drill bit marked but changed to another unmarked one and went in too far. 

This has now resulted in the oil leaking from the engine into the stud location. I have it taped and threaded for an 8 mm bolt or stud. 

 

So my question- I am asking here as I am sure someone has seen this before.

What can I do to stop this oil leak - options. 

1.  Put in a stud with loads of loctite on it. 
2. Put in a 10mm long grub screw with loctite on it to tho and block and seal the hole.

Don’t know if these will work but I would appreciate you thoughts or products etc etc you may have that will sort this issue for me. .

 

The stud location from the back of the car is on the left and nearest to the back - end stud 

 

I would really  appreciate your help on this matter

 

Regards & thanks

I think you are going to have to experiment with sealants.  Has to both be oil resistant and handle the exhaust temperatures.  I think the idea of a stud is a good one to try.  Maybe a stud and some sealant on the threads like this would work:
