Removal/Replacement of valve seats

Valve seats wear & eventually valve seat recession causes difficulties with tappet/ valve clearance setting with the result of lost performance – Where possible, fitting of new valve seats rectifies this problem, also this process can be used for the conversion of engines from “Leaded” fuel to “Unleaded” fuel, along with valves & valve guides.

Note:- due to age, proximity of valves to each other & original materials used, not all engines can have this work carried out.
