Please advise**Civic 1.5 EX-T hatchback knocking sound

[Shankmeyster]

If you have the v2 then you can see the K Control and the Knock Count on the display or in a datalog if you don't have the v2.

I have the 1.2 how do I go about data loging? Do I need to run the car hard or just normal drive?

I thought the 1.2 had datalogging capability? There should be a how to on the website.

Well, the sound returned on Friday and took it to Honda, they had me return Saturday and drop it off this morning. According to the tech, it may need a new cylinder head. Not sure yet as he is speaking to corporate on how to proceed. Will let you guys know what they find. Car has 34k miles.

Here is an update. The oil was very dark, 70% oil life on honda minder. The valves were loose, they were adjusted and noise is still present once car warmed up. They are ordering a new head, since there was some cam scoring and also on cam bearings. I was always easy on the car, thoughts on the cause?

cam scoring is the oil dilution showing its ugly head. I bet if the cam is scored you are having main and rod bearing damage as well. If the knocking doesn’t go away with a new head you should be getting a new engine.

Here is where its at. I purchased the car 4 weeks ago. Have had the ktuner with tsp tune for 3 weeks, the intake for 2 weeks and exhaust for 4 days. Im in NC and its been around 90 temp wise. I just drive to and from work on camp lejeune and havent driven it hard. Should I reflash to stock and take it to the dealer? Will I have to remove the prl cobra intake?

So, if I'm reading this correctly, you purchased this used with 30,000 miles on it? It's very possible the car was abused by the previous owner and not simply oil dilution as the previous post suggests.

There have been few documented cases of 10th gen Civics with oil dilution based failures.

Oh. Update. They ordered the whole top and bottom because noise was coming from bottom main bearings, and there was tiny metal in the oil. Oil looked like it was 15k miles old. 7200 worth of parts. Oh, car was not abused before hand I beleive. It was a lease driven by an older lady.

You can get a whole engine for that price.

Wow. You basically get a new engine. Congratz! I think....

 

[CavCat]

I agree. Thats what honda is paying for the parts. They said the 2.0 is around 10k for the accord and the 2.4 is around 13k. Dem2757 was on point about the main bearings. What could have caused all this?

 

[CavCat]

I just wanted to keep us all posted. These engines have issues and makes me worry for longevity

 

[zspeed]

You can get an engine from a salvage yard like TAE used autoparts, Giant autosalvage, etc.

 

[CavCat]

Well, im under warranty luckily. Im going to ask Honda to extend my 3/36 since it needs a whole new motor basically. Things can and will go wrong when they are putting a motor together. It comes in sections, top and bottom etc

Hoping for the best for you.
