    I strongly second this one!

Simon

唔駛急喇.
有排整呀.
因為 J 左.

Simon

上次換cam帶2008年8月10950miles
而家走左齒, 2010年4月只係一撻就出事, 掃左. 120691miles.
只係20000miles.
真係唔好停.唔好停.只係唔好停止行佢車, 就唔會咁不正常時間走牙.

Simon

好在有個盤頭用, 只係要換valve guide, 生氣valve, 阿良話cam有都可以照用.
不過梗係唔好啦.果套黑仔野唔要啦. 全換.
timing belt 7774591
tensioner bearing 5997325
balancer belt 7614999
bearing 5499795
bearing 7541712

不過要埋盤頭掙口.
Cylinder head gasket 7709257

Simon

因而既然拆晒, 就port埋盤頭.
打滑生死氣, 但生氣port會加噴沙整花佢, 令電油可以有效霧化.
即係...race tune part I

Simon

快意16v turbo 副引擎條cam帶個壓轆, 因為唔係用彈弓拉住, 所以無自動壓緊功能. 其實同年有好多日本車已有彈弓, 德國車用緊油壓頂, 所以好易忽略左tensioner嘅保養.
維修manual也有建議收緊cam帶壓轆.
如果我地係50000km或3年換cambelt, 每20000km或一年便要收緊tensioner. 時間只係0.7hr左右. 比換cam帶時間少好多.

    Same applies to 20VT?

Simon

20v turbo 引擎應該唔駛定期校緊, 因為係用彈弓自動adjust tension.

    Thanks!

You may also consider to use 薄淨口，it has the similar effect as skimming the head and increase the static compression ratio, it would improve the initial pick up response of the engine, but you can not use big big big boost any more!  Might be something that you could discuss with 良師傅！

Simon

磨呀磨呀磨呀.....
打到滑一滑, 令一令.

Simon

已經裝晒嘩佬上盤頭, 今個星期應該會裝上去車.

古惑強

如果有埋flow bench去度正flow balance 就一流喇！

Simon

阿良已經裝晒嘩佬準備放上去.

Simon

安裝中.
話說阿良安裝時, 用支細風炮左左右右都拆唔到粒曲軸螺絲, 於是借左支軍用級迫擊砲咁大支嘅風炮黎拆.
不過如果方向唔啱, 一鬆即斷. 所以今日打鑼咁四維打搞你地, 麻煩晒.麻煩晒.
後來阿ray問左康仔, 一有經驗人士內幕, 即時安心晒.
阿良....發炮啦......
不過, 我都係成個鐘頭後先夠膽打去問佢.

Simon

佢精神嗎?
