325i camshaft for used cylhead should I buy new or used?

[markus_74]

hello

need advice again, I have used 325i cyl head, but the camshaft, valve, rocker arms and rocker shaft is badly worn.

but my question is do i should replace the camshaft with the new one? or used one is OK?

my opinion is used cyl head is may be has slightly worn in the bearing and my number 3 bearing look the worst and the other is OK and the used camshaft is slightly worn so it will be too much loose tolerance?

thank you

The bearings on the m20 cams are massive compared to the load they take, unless the cam is flopping around in the hole then I would not worry too much.

If you are really worried about the surface finish then you may be able to find someone willing to spread some lead onto the journal and size it with a hone, not an ideal fix and tricky to get to bond with the alu but a perfectly viable solution.
