threaded studs - what makes the engine side stay in? how tight?

[Andrew Vanis]

Just cleaned up and reinserted the oil filter cover studs using blue thread-lock per BassCliff's page. (ever wonder why blue thread-lock comes in a red bottle?)

Made me wonder though,

1 - is thread-lock the only thing that makes the engine side stay in?

2 - how tight should the engine side be? I'm guessing we don't want it too tight or too far in as then the beginning of the female threads would get damaged by the non-threaded part of the stud. (I put mine just barely snug)

Youngotta give them a little more than "barely snug"..tighten nthem with the same amount you would do say a regular bolt..around 10 inch pounds,or so. The thightness coupled with the thread locker ism what is the combination that will hold them in.

Thread locker simply is a tool that keeps a tightened bolt from coming out...once it is actually tightened of course!!!

Just the studs (install the studs and let them dry) or the studs with the oil cover plate installed and nuts tightened?

If it's just the studs then I am wondering what keeps the beginning of the female threads from getting damaged by the non-threaded part of the stud.

Put 2 regular nuts on then stud and jam them together....thread the stud in and tighten it down. next unjam the 2 nuts and remove them leaving then stud inn the engine..done. Repeatb on the other 2 studs.

The shoulder isnt gonna hit the female threads and scour them up.....the shoulder is how far the stud ism supposed to go in...just put them in for god sakes.

Are the engine case threads stripped? The stud should thread into the cases and not pull out. You don't need thread locker, but it's nice to keep the stud from spinning if the nut binds.
