作者: kaihoc 時間: 2009-8-1 01:34 PM 標題: NISSAN SR20 Engine 超大 "閣閣" 聲..

呢個問題好常發生喺 16 萬以上既 SR20 egnine..
唔知有無人知係壞乜? 係大聲都唔可以接受.

但力量無事的...

乜聲？聽唔到，好難答你
幾時有？怠速有無？加油才有？
蛙佬腳、火位錯、車頭鍊、爆傘、大細杯士................等等都會

任何時間都有. 一著就有, 高轉d就密d咁..
炱速加油都有.
係好大聲, 好似鐵鎚打咁既聲..

我見好幾架pulsar (同engine) 都係咁的...

似上面還是下面？
有無放偈油睇下有無碎片/銅粉？
返工先

作者: kaihoc 時間: 2009-8-1 09:28 PM

就咁聽似上面中間..
未放機油睇...
前車主話之前嗰個都係咁, 所以換左engine, 換左二個月又再係咁...

上網搵到, 個聲完全一樣.

搵支幾尺長嘅螺絲批督著個timing chain cover，另一頭就用隻耳仔聽下D聲是否從裡面發出黎
好似係個timing chain tensioner響咁

見唔架車好難估，響聲從來都要聽到先跟到，除非之前跟過

我試過用手指頭掂住.

嗰一下下knock, 係喺哇佬cover最大力. 中間汽缸細d.

咁就有機會會係生死氣蛙佬油壓頂瓜左
要拆蛙佬冚測
好似攝蛙佬咁轉個偈
每隻rocker arm都搖下佢，睇下有無一/兩隻特別鬆，特別多虛位
搵到就恭喜你

is sounds like a rod-knock man, if is coming from the block. and if is from the head then might be a lifter issue. but after watching the video thats a engine knocking noise for sure. timing chain tensioner only makes rattling noise when is bad. aight let me know what find.

sounds like a spun bearing in your engine block, time for a new engine, it happened to my old one and you basically have 2 options. buy a new motor and hoping it's in good condition or 2nd build it back w/ all new parts (piston, rod, etc)

Time for a rebuild mate! Not much you can do except to get a new engine or take the motor apart and replace the internals.
