Hi John,
I don't have my car. Covid-19 & all that.
It was a very strong spring. A quality spring best used elsewhere.
When I used it a while ago, it did compress the valve springs so I could not rely on that function & just closed the gap and then counted the clicks. Should be OK now.
I tried to measure the torque required now but my torque wrench does not go that low.
Cheers,
Iain.
