Haha, I will never be accused of that ,Tribute. The inside of my 94's filler cap looks just like new and not a bit of build up. We went looking for a used car for our parents a few years ago and first thing I done was take a look at the filler cap inside... It was caked up with burnt motor oil /creosote looking.... bleck. I said no way and good bye to the salesman- FYI- they did get a great car a bit later..
Now ... on my then new Kioti dk45 tractor, First oil change was ok but the transmission filter... whew!! As a last resort ,I even took off the water filled super heavy rear tire to get a better grip on the filter, but it wouldn't budge.. tried my twist- a -chain invention- nope the filter started caving , Got the screwdriver and put it through, turned and it started tearing in the filter, Called the dealer even.... he said that it was sometimes a horror story on the first on factory filters because of paint !!and offered little hope .. ahhh , that got me thinking.... paint... cut the paint seal!!
... Finally I got a sharp knife blade.. slowly and carefully rocked it back and forth till I got through the seal and worked it all the way around... .. I also said a prayer to the Good Lord , tried again to twist it and off it came. .. Then I had to put that heavy tire back on and was sure glad I leaned it against the barn wall and not flat. - I am sure He helped with that too because that thing was HEAVY .collie
