I may have screwed up ....more than once

I primed a 318 and the open oil pressure port shot oil right up my nose. Couldn't (wouldnt) do that again if I tried. That is uncomfortable!!! I replace the backlights in a 55" lcd TV and fired it up...nothing. Forgot to plug the 10 led strips into the harness! Had to take the whole LCD panel off again and those are about as fragile as a snowflake at that size. Many shops won't attempt it, not worth the liability of breaking that 1mm thick glass sheet. Work slow and methodical, enjoy the experience. That's what this hobby is about
