As far as the rockers being loose, the rocker bolts have to be torqued to 21 ft. lbs. when the respective cylinder is at TDC compression.
Does he have a Factory Service Manual for his Heep? If not, getting one is way overdue.

Tell him the rocker arm bridges have been butchered from improperly removing and reinstalling the rocker arms. That's why they are crooked. He needs to buy new ones and install the rockers per the FSM.

He could try "staking" the valves (an old radial aircraft engine trick) by placing the respective cylinder at TDC compression, applying 100 psi to the cylinder (like a compression loss check), then hitting the rocker arms directly over the valve stems with a rubber mallet several times and see (hear) if the valves seat. If there's still pressure loss in that cylinder the valve is cracked or burnt, or the valve seat is shot. Of course, this won't help with bad piston rings. This is generally used to dislodge any crud between the valve and valve seat. If the valve is being held open by a bad valve stem/valve guide the problem will persist.

I'd just like to point out that I prophesied way back on page 10 that this guy would get banned long before this thread got to 30 pages.
