Скачать или смотреть 1977 Porsche 911 turbo: Valve and rocker shaft seals [4K] Ep84

Today I will work on the valves. I will find a way to compress the valves, get the locks out and pull the valve spring out. I will then remove the valve seals and replace with new ones. I will also pull out the rocker shafts and put seals on those. No time for adjustment today but I am confident this did good things for oil leaks under the valve covers.
