Demosta Posted September 15, 2019 Report Share Posted September 15, 2019 (edited) Hello everyone! I just start to clean 4age bigport head, and find out that 4th exhaust cam bearing looks different than others.. Is it too Bad, or can i still reassembly head with these caps? Camshaft looks good only bearing cap had that little groove, just where camshaft had "lubricant hole" (or what IT is correct name ) so, do it carry oil all over that 4th bearing cap, and everything is okay, or is cap (and head) only a trash? Cams roll still smooth, when i turn them by hand. That groove on cap had smooth edges, not sharp. Other caps looks good yhen only had minimal Marks wich is normal. Engine runs good before disassembly head, only idle was quite high Edited September 15, 2019 by Demosta Quote Link to comment Share on other sites More sharing options...
altezzaclub Posted September 15, 2019 Report Share Posted September 15, 2019 I wouldn't worry, these are old engines and all the ones I've seen show some dirt scours like that. Quote Link to comment Share on other sites More sharing options...
