Timing belt tensioner bolt question

Hi there, the big timing belt tensioner bolts on my 328 had some white goo on the threads upon removal. Do you folks put anything on the tensioner bearing bolt like antiseize, or alternatively loctite?

Thanks!

 

Thank you Thorn, I think I'll clean off the white oily residue and use a small amount of torquing compound on the threads. Mostly I was looking to see if anyone uses threadlock on these.
