Why no lock-washers?
This is not just an weird question like I sometimes ask. It is a very important question that deserves a really good answer.
Every time I’ve checked the nuts on the intake-exhaust manifold on my A, they could be tightened more. If I remember correctly, the head bolt nuts on a model A have to be tightened on a regular basis. It seems that everything that does not have a lock-washer has to be tightened periodically.
Why weren’t lock-washers used in all these places? I don’t care if they were split-washers, star-washers, or even bell-compression washers. Why wasn’t something used to keep those nuts from working loose as that engine heated and cooled.
If there is a good reason why they weren’t used, I’d really like to know.
