Metal Shavings in Oil: Honda Grace Engine Crisis Alert

Hey there! I've got some experience working on cars and had a similar issue with my 2019 Honda City, pretty close to your Grace model. The symptoms you described really ring a bell! Last year, my car started showing the same warning lights, and I found metal bits in the oil too. Turned out the cable harness on the oil pressure control valve was soaked in oil and damaged. Took it to my regular mechanic, and they had to replace the entire harness assembly. Cost me around 350 Euro, but it fixed the problem completely. Before I can share more specific advice, How many miles/kilometers are on your car? Have you noticed any unusual engine noises? When was your last oil change? Looking forward to helping you figure this out!

Thanks for sharing your experience! My Grace has 218103 KM on it, and I just had the oil changed during my latest service two weeks ago. Actually, I've started noticing a slight knocking sound when accelerating, especially when the engine is cold. It's not super loud, but definitely wasn't there before. The metal shavings really got me worried since the car isn't that old. Your tip about the cable harness is really helpful, I'll definitely have my mechanic check that out. Did you notice any performance issues before you got yours fixed?

Hey again! Thanks for those details about your Grace. Yeah, that knocking sound combined with metal shavings isn't something we want to ignore. Actually, before I got my City fixed, I did notice some performance issues, mainly hesitation during acceleration and occasional power loss, especially when the engine was warming up. Sounds pretty similar to what you're experiencing. The knocking noise you mentioned is particularly interesting because that's exactly what tipped me off that something wasn't right with mine. I've actually learned a lot since my issue last year. The combination of metal shavings and that knocking sound could also indicate bearing wear, which is potentially more serious than just the harness issue I had. Don't mean to worry you, but better to catch these things early! My suggestion would be to get it checked ASAP, and specifically ask them to check both the oil pressure control system AND the main bearings. When I had mine fixed, I wish I'd asked for a full inspection right away instead of just focusing on the harness. Let me know what your mechanic says, really curious to hear if it's similar to what I dealt with. These Honda engines are usually super reliable, so it's worth getting to the bottom of this!

Thank you so much for all this detailed information! I really appreciate you taking the time to share your experience and advice. The similarities between our situations are quite striking, and I'm definitely more concerned now about the bearing wear you mentioned. I've already called my mechanic and scheduled an appointment for tomorrow morning. I made sure to mention both the oil pressure control system and the main bearings, just as you suggested. You're right, better to be thorough and catch everything early rather than face bigger problems down the road. The performance issues you described during acceleration really match what I'm experiencing. It's actually a relief to know someone else has dealt with something similar. I'll definitely update this thread once I get the diagnosis from my mechanic. Thanks again for your help, it's given me a much clearer direction on what to look out for!
