Hi Scott, Tom, Mark,
Thanks for the additional insights.
When I wrote "square" I really did mean the "flat" seal, just didn't know
the terminology. Also, asked because the new plugs came with the washers,
and now I know that these are crush washers.
So, I am going to go for it.
- Anti-seize on the plug threads,
- screw the timesert onto the plug
- then put the thread locker on the outside threads of the insert. I'll use
the material that came with it, the package says it is for spark plug uses,
so I'll have to trust that it is valid for higher temperatures.
Then screw that combination in there, torque to the 22 ft. lbs that the
Bentley says. Let it sit overnight.
Only other alternative I thought of is to use one of the old spark plugs and
torque it to a higher value to maybe get a better seat on the insert. Then
wait a day, remove the old plug, and install the new one. Any views on this
idea? How much higher could I set the torque wrench if I used and old plug
first?
Sorry to be such a ninny on this one, just seems like a really dangerous
area where I could mess something up quite bad.
Thanks!
Roland
