Car has about 115k miles. Noticed recently that it makes a weird raspy rattle at startup. Mechanic (heard voice note i made) said it sounds like timing chain loose. Paid them to adjust tension (couple hundred no biggie). when I picked it up, I noticed it made the same sound and I went back into the shop and told him I was assured that it could stay that way for a couple weeks while it adjusts or whatever. months later I called them and told them it was still happening and the tech who answered the phone told me that it is not uncommon for these Hondas because the oil drains all the way out of the engine and when you called start it it has that dryer at all and there’s nothing we can do about it. Any insights or experiences with this?
