[問題] NISSAN SR20 Engine 超大 "閣閣" 聲..

kaihoc

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

kaihoc

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...

carwing

似上面還是下面？
有無放偈油睇下有無碎片/銅粉？
返工先

kaihoc

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

kaihoc

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.

carwing

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.
