After realising my rocker cover was from TMD a company owned by , from what I've read , I good fella called dave burwash I thought that his stamp should be on it and a little respect shown by myself. I will admit I never knew who the company was or who he was until I went searching but still I think a little respect should be shown. I also looked down the spark plug holes because someone said I may be able to see part numbers for a forged engine !! And I can't , unfortunately , but still need to take the sump off on Sunday to find out for sure . The mystery continues
