hydraulic or solid tappets?

its difficult to tell without taking one out (and you cant do that unless you have a collapsible pushrod tube)

its fine to have a fraction of a gap on a hyd..
Its should have hydraulics in but its had a rebiuld? so who knows...

It may be possible to remove the pushrod and see down the tube, if you can make out a clip holding the cntre piece in the outer of the lifter, then they should be hydraulic.. I doubt the solids are 2 piece so could be a way of checking...

or incompetant prev owner/garage etc....

Oh.. there is a secondary problem (or potential) as solid lifters shouldnt be run on an hydraulic cam... the ramp rates are quite different and this can easily wipe out the camshaft/lifters... all to do with direct/indirect/preload....
