nikolaos Posted February 3, 2018 Share Posted February 3, 2018 Hi to All, I am in the process of rebuilding a 200tdi defender engine I recently purchased. After inspecting the cylinder head I noticed some marks next to the valves as shown in the pictures. Does anyone know what is this and what caused it? Do I ignore it or more attention is needed? Thanks in advance!! Quote Link to comment Share on other sites More sharing options...
western Posted February 3, 2018 Share Posted February 3, 2018 if there are no hairline cracks in the black areas its probably just remains from the combustion process, the valve seats are inside the black areas, you could get the head pressure tested/skimmed/cleaned prior to fitting.

Snagger Posted February 3, 2018 Share Posted February 3, 2018 Those look like scorch marks from bad injectors. Were they very dirty when removed? Quote Link to comment Share on other sites More sharing options...
