just a little piece in a big "engine piece puzzle". but if someone thinks that those shiny homedepot quality washer are fine .... you´re 100% wrong and even more annoying: it might cause some after-effect.
in this case over here a broken cylinder head
check out the difference: left ~5year old homedepot washer and on the right a 49year old washer taken from an engine. my mum would spot the difference ...
sometime it is really expensice to use cheap parts
