  • Q:

    I wrote in a day ago but didn't give right info. as it (plug) isn't 1-1/8 to 11/4 inch as said but upon checking back at store and talked to different employee there IS a smaller size for my 95 Riviera 3/4 to 7/8 th's and fits right in and expands to what seems to be the tightness needed,But upon trying out fit in the one right of alt. a little soft plastic/ ring fell into engine,One wasn't in other hole under alt. it must have ether shot out already or fell in to engine already,I have been told by a few people that since it is a soft rubber/plastic small ring it would not matter and grind down and to change oil soon after. But this is a BIG matter for me as it is my car and to turn into a costly problem and/or a LOT of work.

      Hi Dylan from Chicago! We’re here to help! Yes, some people might say it is okay to leave the plastic piece and it will eventually melt down in the engine heat, however I would not risk the engine that way. My recommendation is that you drive to your local repair shop. Explain to them that you want to retrieve the plastic seal which is probably located in the engine. They should have a boroscope that might also work in locating the plastic piece.
