I have a 2024 Honda Ridgeline Trailsport, with around 78,000 miles on it. Last weekend, I was driving with cruise control set at 88 mph (no check engine lights, no decrease in performance, no noticeable problems). Once I started slowing down at on off ramp I started to hear what I would describe as an engine knocking noise.
I stopped at the gas station and shut down, in fear of causing damage to the engine. I checked the oil, and while it was dark it looked typical to me for a vehicle that is about due for an oil change. The oil was on the low side of the dips tick, but it was showing on the dispstick. When I would start it up, I would notice a muffled, squeaking noise that lasted about a second or two, and then just the consistent knock knock.The changed with engine RPMs when in idle or drive.
I had the vehicle towed to a Honda Dealer and they said the oil was dirty and on the low side, and that I needed to get the engine replaced. They didn't really provide any additional information.
I don't feel like the dealer made an honest effort to investigate the issue, and want to bring it somewhere else.
Do you have any input on the cause of the knock? I'm thinking hydraulic tensioner for the timing belt.
Thanks for you to time!
If it's a bottom end knock the damage is done and you would need an engine. However that is the worst case scenario and has yet not been established.
If the oil was just barely showing on the dipstick that is too low. Your dipstick will have a safe range on it and if the oil is not in that range you risk engine damage.
First do an oil and filter change so you have clean oil up to the proper level. Cut open the old oil filter and check for any metal particles or shards due to excessive wear. Use a mechanic's stethoscope to try locating the source of any noises.
The dealer is usually the worst possible place for diagnosis and service unless you're dealing with a warranty issue or a recall. You need a good independent mechanic who is willing to take the time to do a proper diagnosis. (Expect to pay for diagnostic time.)
Thank you for your input.
I agree, if the damage is done, its done and I need a new engine. I just don't feel confident in their diagnosis.
The oil level IS showing a the bottom of the safe zone, not the bottom of the dipstick.
The knock is definitely noticable, and doesn't sound like it's at the top of the engine. It doesn't sound like metal on metal, necessarily, and is quiet enough I couldn't hear it with road noise at speed.
I've been trying to get a hold of some shops in the Billings, MT area but nobody ever answers the phones unfortunately. That's life.
@shopf If unable to diagnose the problem yourself you definitely need some expert eyes on it. Unfortunately we can't help much as far as finding a good shop in your area. We do have a small section of referrals in the FAQ but none for your area. You'll want to avoid chain shops as well as dealers. Pep Boys, Midas, Goodyear, etc. are to be avoided especially for a potentially serious problem.
