Well after getting fed up relying on pumping oil into the spring loaded stock tensioners for setting the timing - I drilled
out a set of old tensioners, tapped in some threads, and made some lockable ones.
The springs are still in, so all you do is install the tensioner, hand tighten the little bolt using fingers and then backoff
1/2 turn... voila...
The bolts were free and so were the tensioners :-)
Just wanted to share as it beats buying the expensive Porsche ones
