난이도 & 준비물
증상
2005 혼다 시빅 EX, 냉각수에서 배기 냄새가 남. 지난 한 달간 냉각수가 서서히 누수되고 과열 발생. 마지막 냉각수 보충 후 3주 동안 지속. 마지막 과열 시 냉각수 저장소가 가득 차 있었으나 갈색 빛깔의 냉각수 발견. 배기 냄새 후 헤드 개스킷 교체 완료. 교체 후 P2646 코드 발생 - 오일 부족 또는 누락 의심.
처리 내용
배기관에서 냉각수 냄새가 나면 냉각수가 연소실로 누수되어 연소되고 배기로 배출되는 것. 냉각수가 연소실로 유입되는 유일한 원인은 헤드 개스킷 또는 흡기 매니폴드 개스킷 손상. 개스킷 손상 위치와 심각도에 따라 증상이 다름. 냉각수가 엔진으로 누수되지만 오일로는 누수되지 않는 경우, 오일 수분 혼합이나 수분 오염이 없을 수 있음. 소량의 누수로 인해 흰 연기가 적고 냄새만 나는 상황으로 보임. 헤드 개스킷 교체 후 P2646 코드는 엔진 오일 부족 또는 오일 레벨 센서 문제를 의미. 교체 후 엔진 오일 레벨을 확인하고 필요시 규정량까지 오일 보충 필요. 오일 누수 여부도 확인하고, 필요시 센서 교체 또는 진단 필요.

With the untimely death of my daily Ford Focus Estate Titanium X recently it was time to find a new daily. The Focus was struck by a DHL lorry who straight-lined a two lane roundabout with me on the inside lane. Minor damage sustained but with the car on 127,000 miles the repair cost outweighed the value. Insurance pay-out was £2000. I thought about arguing for a bit more but it was a fair valuation.The Focus was both brilliant and terrible all in one. Nicknamed the Silver Bullet, it did every single family duty you can imagine from family holidays 4 up + 2 dogs, to tip runs, Ikea errands and

For those who have followed my previous MX-5 thread, you may remember that I was considering purchasing a new car for some time. The arrival of my son hadn't forced my hand per-se (we have another family car), but with the MX-5 being a two-seater, it's become such a lonely car. My wife can't come with me on any trips as there's now three of us.It's time to sell, and while I'll be sad to see it go, I'm excited to start another chapter. Farewell Pip.I had considered an ND, but the above requirements quickly ruled it out. My wife's been wonderfully accommodating with the car, allowing lots of fre

There is a specialist on Boxsters in Sunbury that has consistently good review and has set-up his own Facebook group where he gives advice and support to help people work on the Boxster - Paul Torque Boxster. I booked in for a minor service, to have the water pump, thermostat and coolant changed and the oil pressure relief valve changed to a later spec one. Paul suggested that I get a new oil filter canister as they need changing every few changes and I didnt know when it was last changed. I can help thinking Porsche parts might be a bit cheaper if they didnt give wrap them!
