Shaftsbury, Vermont (SW VT) | I never found it necessary to do anything to the hole in the head when replacing injectors. Just plug and play.
I have an expandable spring wire tool for cleaning valve guides that I could use, but never have felt a need to use it. If you feel the need to make sure there is no carbon to mess up your new carbon dam seal, you could take the seals off your old injector, and work it up and down in the hole with a little penetrating oil, and follow up with a rolled up wipe rag on a screwdriver, or use a rifle bore bore brush and then a patch pulled through one of the tips with a slot in it. |
