Great video, it's a shame the gopro crashed while doing the change on the valves. Did you have to move the pistons to TDC for each cylinder to prevent the valves dropping too far as I assume you had to remove the circlip from the valve to remove the spring?

[@NENTECHM57]

Yes that was the way to do it, 2 cylinders at the time then spin the crank and same again. To be honest it was easier to do than on the bench with head moving about. Just a job to take everything apart and back together

looks like an intimidating job

Nice video. I got question about spring. I got e90 m57d30 with hybrid turbo and other stuff mod but can valve spring use from other cars example?

1.4 tsi vw is one option. There are blue and red versions, blue is bit softer, red is stiffer

Any sound difference driving on load after spring upgrade?

[@NENTECHM57]

I can’t tell, but people say when they are installed it runs bit sharper

[@beautyheart5681]

How many bars springs can hold ? 4 5?

[@NENTECHM57]

These are 30% stiffer than stock, worked fine on 3bar of boost.
