Are they gaskets or like donuts. 50-60 ft lbs sounds like alot to me but I will try to find a spec on that.
Flange gasket with 2 bolts -- like this one.
1966 Chrysler Newport 8 Cylinders 6.3L 2BL
tighten exhaust pipe bolts to 40 ft. lbs
I see it is a gasket type. I would remove the gasket and check it, if there are studs and nuts, run a die up each stud and clean up the treads and use new nuts, then make sure you tighten them up evenly.
Sorry -- what's the tap through the bolt hole for? Just to clean it out?
Then are these holes normally threaded? The bolts that were on there -- and the replacement bolts that I have -- just slip through the holes on the flange -- they're not threaded in. (I didn't notice any threads in the hole but wasn't looking for them either, since the bolt just slipped out.)
Ok - will do.
Because there were no threads, it took two people to get these bolts on/off. I thought it was kind of strange to have no threads in this application, but the car is 45 years old after all.
