well, had my cx5 pcm software updated for the 'fix' today........ took about 20 minutes.....
the mechanic that did the flash said version he is using now is 13.06........
he said increase oil pressure to keep rocker arm in place plus the timing was off and this
new pcm fixed that also....... I asked by how much oil pressure was increased ? could it cause oil
leaks in future ? he said mazda headquarters don't tell him stuff like that ......
I asked if this new pcm just masks the problem ? he said no, and if the rocker arm falls off that
you'll know it because the timing will be off and you could hear it ........
So, sorry , not that mechanical , and best I could do............ Oh also , no to removing the valve cover
to check it it's already fallen off......... guess he could hear it if it did...
