    Solid. Adjustment is via shims between the valve stem and the bucket. There is gap of approx. 0.010" between the cam lobe and bucket when the valve is closed.

    Solid lifters maintain their clearance under all RPM conditions, but are harder to setup initially. Hydraulic lifters are quieter in operation and easier to setup, but will eventually "breakdown" under extreme high RPM conditions, causing the valves to bounce. Hydrualic lifters are setup with zero gap (or lash).

    Hi Peter,

    Thanks for the response..

    How hard to adjust?
    any special tools required?
    how would I know that they need adjusting?
    Any else I would need? i.e new rocket cover gasket

    They're easy to measure but hard to adjust. Why do they need adjusting? If they're excessivley noisey, and outside the range below, the clearance has increased, meaning something is wearing. You should be able to re-use your gasket. You need a set of bent feeler guages.

    exhaust 0.014 - 0.018"
    inlet 0.006 - 0.010"

    Well.. do I?? that was part of my question... do I need to have them adjusted? How do I tell that I need them adjusted?

    The NRMA guy said it was an outside chance that a 'lifter' was too tight and sticking and that could cause the rough idle...

    Could be. If a valve has receeded into the head through seat wear, the clearance would decrease. It might be OK cold, but as the valve grows with heat, the clearance may decrease to zero or negative.

    Only way to tell is to measure them when cold.

    Sorry to hijack the thread a little but just wanted to clarify.

    Peter am I am correct in saying that the Mi16 motor actually has hydraulic and not solid lifters - or are they solid as with the 205?

    Correct. Mi16 are hydraulic. Just like a 6 cylinder Holden!
