Tried to googled the problem, and it seems it maybe due to the Timing Chain Guide. Common issue for 4.4i V8 engine since the guide is made of plastic.Sent to first workshop (which in the recommended workshop list on one of the thread here), they said engine problem, need to overhaul (cost RM26K) or change engine (cost RM30K). Too expensive..Then went to 2nd workshop (recommended by so many ppl in this forum), the mechanic said noise coming from engine (confirmed from engine since they have remove all the belting, and start the car wif only the engine running). They said overhaul is one option but labour cost could be high since they need remove the engine first then open up the engine the check the problem (but the cost will not be as high as RM26K). The second option is change to half cut engine. They haven't came back to me on the 2nd option cost. But probably not more than 15K.So would like to have your opinion on whether I should just change to half cut engine or go wif the overhaul option.Based from what i read, most of the ppl who experiencing this problem, they usually change the rail guide and on also something related to vanos, the noise is no longer there..Hope to have some advise.. I'm a newbie and this is my first experience owning a bmw..Thanks!</p></blockquote><p></p>
