I'm just cleaning up the cylinder head on a 1989 9000 turbo 16valve 2 litre B202 engine.
Everything looks reasonably within tolerances except the valve head diameters. Mine look fairly clean, not badly eroded (for 89000 miles) but the inlet diameter is 29.5mm and the exhaust is 26.5mm - Haynes quotes 33mm and 29 respectively.
Does anyone know if Haynes is correct? These valves certainly don't look to have eroded by that much.
Any help appreciated, thanks in advance.
