Full disclosure, I know nothing about engines. I feel embarrassed to ask, but it seems like something should be in this hole. Short backstory, purchased it used, everything the seller told me about it has been all lies. I’ve been having issue after issue and my husband is not willing to help me with anything. I’m having to learn things as I go. I do plan on changing my oil today and switching to synthetic. I’m sure they will notice and I’ll feel stupid. My first time posting with a photo, so forgive me if I have to put it in comments, I’m still new to this page.
