According to my workshop manual 18RG bucket clearance should be 2mm approx, both inlet and exhaust. Intake valve clearance 0.24-0.34mm. Exhaust valve clearance should be 0.29-0.39mm.
Calculate thickness of new pad so valve clearance comes within specs
T1 **Thickness of pad used
A **Valve clearance measured
Did you mean 0.2mm or are we talking about same clearance?
Holes for the buckets were from 38.05mm to 38.16mm from memory. Shouldn't the bucket diameters be something like 37.90mm.
I managed to obtain a RG head but it's blank. I'm going to get OS SS-valves for it. Saabs have 38.00mm buckets so I'm going to machine these to fit.
