📋 Discussing: Rod Knock (87% confidence)
🤖
I see you've got a potential rod knock issue. This is a serious problem. How can I help you understand it better?
Is it safe to drive 10 more miles to the mechanic?
🤖
I'd recommend being very cautious. Drive slowly, avoid high RPMs, and monitor your oil pressure. If the knocking gets worse or you see warning lights, stop immediately.
How much will this cost to fix?
