Slant 6 Exhaust Manifold Washers
I am replacing a cracked exhaust manifold on my 1965 slant 6. I found I was confused as to how the washers are oriented, and where the three different types of washers go. So, I read a ton of posts, read my '65 Plymouth Service Manual, and spoke to an old MOPAR mechanic. Here is what I learned.
The middle-top stud gets the domed stainless washer and regular nut. Dome side faces up.
Each of the two outside-top studs get a thick brass washer and special slotted locking nut. Slots on the nut face down towards the brass washer. The inside diameter of the brass washer squeezes the nut onto the stud and keeps the nut in place.
All the rest of the studs get the domed stainless triangle washers and regular nuts. These washers also go dome side up. All nuts are tightened to 10 ft lbs. Hope this helps anyone who might be replacing an exhaust or intake manifold.
