Length spring valve body pressure ?

Forums

Hello,

What is the length of origin spring who is in the valve body pressure on the crankcase of distribution for 850 MK3 ?

Thank you,regards Francis

The relacement springs are 1.171" or 29.743mm. The earlier pre-mark 3 engines used shims to help get the correct pressue valve release value. I believe that the mark 3 just relied on the spring length being correct.

Thank you very much Phill for your quickly answer.

For my MK3 the relacement spring are 30 mm and there is a shim like the part-listwink.
