Went to change the oil last week in my Triumph, all going well, put the sump nut in tighten up as usual, then pour the new oil in.
All seems well until I notice that it is dripping, maybe I didnt tighten it enough, seems a bit loose, better tighten it a bit more.
*CRACK* the sump pan splits. Oh shit I forgot to install the crushable washer. Bollocks.
30 quids worth of oil dumped into the road and 210 quid for a new sump pan and gasket...expensive mistake! I have changed the oil dozens of times in the past, mind on other things.....!?
