Since very end of last trip to Redwoods National Park/Oregon Coast, I felt some metal is clicking when vehicle’s speed is increased, but immediately disappear after the speed is up and more painfully irregularly.

So much of our freak-o-meter went up, the unlimited search on youtube was on. Metal Noise (when speed is up), Metal scratching when speed is increasted etc.. , then every different ones were suggesting break pad problem, transmission problem etc,.

Data science kicked in with extremely mental hypothesis testing ‘Does it make noise when it is uphill or downhill’, ‘Does it make noise when road surface is not bumpy or not’, then one great clue I landed was ‘It always sounds at 20MPH -40MPH. However, that theory was broken when I was testing on freeway it made a noise again around 60 MPH as well. Ah…

At the end of lengthy period of hypothesis testing, came to conclusion this mostly happens when RPM is passing thru 2,000-2,500 and less in the morning; especially when engine works one more step. Then I searched the web and youtube to learn this is more likely the problem of heat reflection metals around the exhaust system getting aging and loose and the vibration from the engine is making it “rattle” – glad it was not a break nor transmission problem 🙂

Went to auto repair shop, and the mechanic simply screwed in one screw piece in the gap at the surrounding cover parts near the engine (Catalyst) and it was fine. His suggestion was using this as molding is the ultimate solution but it will be costly and time consuming 🙂

However, that patch didn’t last long, and about a week later started to hear the rattling again. So decided to go more permanent solution.

So crazy DIY kicked in –

Ordered a ‘ramp’ as I don’t have the jack (and I have been in the need of something to put my car up for other reasons)

Looked at the area where the screw-patch was on – clearly gone 😦

So followed one of the videos suggesting using the metal clamp to hold the covering tight – some suggested zips but clearly got to know that won’t last at here as it was extremely hot with simple driving.

At the end, when the ramp and metal round clamp arrived, put the car on the ramp, dig thru under the car (first time using the back to move around after highschool’s military training class) put two clamps with painful arms with the hope at least one will resolve.

At the end – perfect solution. The rattle is gone now, (although hurt my eyes as particle dust from the car hit my right eye; continuously pumping tears for few hours. (+ countless attempt to wash out with tons of water :))

오디세이가 지난 여행 말미에 시애틀 다와서 좀 밟아주면 뜨르르르 드르링거리기 시작하다가 바로 잠잠해지는 소음을 내기 시작해주셨다.. 아 쒸…이거 브레이크패드 소리는 아닌데 트랜스 미션이 나간건가 걱정 한가득하던 중.. 이성을 되찾고 수많은 유투브 비디오들을 찾아보고 가설을 기반으로 테스트를 이래저래 한 결과.. 속도가 20 MPH를 지나가면 나는구나 싶어서 더 테스트를 해본 결과 고속도로에서 60MPH를 지날때도 그럼을 발견하면서 OTL..

다시 정신 채리고 곰곰히 테스트해본결과 이건 속도가 아니라 엔진 RPM이 2000-2500구간에서 발생한다는걸 다시 확인 (그래서 60MPH 즈음에도 발생하는 거였음) 동네 카센타에 가져가서 물어본 결과 방열판이 오래되고 느슨+유격이 생기면 엔진의 떨림이 방열판/커버에 전달되면서 소음이 발생하는걸로 결론을 내리고… 용접을 하면 시간과 돈이 많이 드니 그냥 고정시켜주는 나사 하나 끼워주는걸로 해결하고 왔다..:)

허나 일주일후 다시 소음 발생.. 아마도 그 고정나사가 빠졌겠다 싶어서 더 안정적인 솔루션을 탐색하기 시작한 결과… 느슨해진 방열판 주위를 쇠로 만든 clamp로 감아주면 된다는 비디오를 믿어보기로 하고…차 밑에 기어들어갈 수 있는 ramp도 주문해서 clamp와 도착하길 기다리길 몇일… 결국 ramp와 clamp가 같이 와서 밑으로 등포복(군대도 안간 난 고등학교 교련시간 이후론 처음..ㅎㅎ) 을 하면서 기어들어가 그때 박은 나사가 빠져있음을 확인하고 clamp를 낑낑거리며 감았다.. (등대고 누워서 손들고 벌서는 구조로30분..ㅎㅎㅎ)

하필 자꾸 먼지덩어리들이 떨어져 오른쪽 눈에 들어가 개고생을 했지만 결국 clamp2개 달아주고 테스트 결과…조용…. 눈물이 주르륵 흐른다.. (특히, 먼지 들어간 오른쪽 눈…ㅠ.ㅜ)

결국 해냈다…ㅎㅎ 이 중고차 비싼 시국에 4개에 5불짜리 clamp하나로 해결…ㅎㅎㅎ
