Hi all,

I snapped one of three studs holding the thermostat housing onto the cylinder head. I drilled out the stud and helicoiled. I used a new stud and nut but now I have a leak through the stud. It looks like it is leaking up the threads so I’m planning to use a thread sealant. Does anyone have any recommendations for something easily available? (Uk based)
