the valves have "encrusted", what a pig work
!The deposits are so solid and thick that they are neatly secured with only one scraper and in a drilling machine.
Who thinks to get them clean again with gasoline additives, he is tremendously mistaken.
It's just mechanical.
Yes, I was careful,
No, I didn't damage it,
Yes,with leopard lines,
In the appendix a photo, unfortunately not very good (left a cleaned valve, middle an oiled valve, right a normal rusted valve).
Tomorrow I'll get the heads with new outlets, I'll be waiting for the bill.
