From what I'm looking at, your car does not have an external fuel regulator at the fuel rail, it's an FLX. It is IAFM+, not IAFM. According to some senior member, IAFM+ were made stronger compare to old IAFM module that always picah

IAFM rosak render the sound "tub tub tub tub tub" from the right side of the intake manifold, where the PURGE VALVE located.


The same car as above, after repaired the rosaked IAFM, only rendered the similar tepet sound like minor "tak tak tak tak tak" sound on the rocker cover.


A more effective way you can identify is:


1) If can hear loud tak tak tak tak tak sound, at this point means the exhaust valve lifter bising, go claim warranty
2) If can hear loud tak tak tak tak tak sound, at this point means the intake valve lifter bising, go claim warranty
3) If can hear loud tub tub tub tub tub sound, at this point means the purge valve sudah koyak, go claim warranty

However, for 1 & 2 is insignificant. Replace or not replace does not really helps to eliminate the noise, its just the way how hydraulic valve lifter works. When enough lubricants, no noise. When not enough lubricant, especially cold start, aircon compressor kicks in, these are the time most car will have loud valve lifter noise. If you think your car is loud, try those Honda B16/B18 series engine, also not forget Plotong Pugra & Wigra 1.8 with 4G93 engine, their valve lifter is much louder than most yellow black diesel taxi.

If you're long hair, make sure you tie it up properly. The method itself is safe to use, but those extra accessories become life threatening if screwed up. Besides, you probably don't wanto dirty yourself with those things hanging around touches your engine bay. be safe

Avoid X1R.

where you found this? i wanna see full thread...
member search feature seems not working.

How about octane booster? seen quite a few shopping complex sell those tablets (dynatab if i m not mistaken) or liquid booster that add in to fuel tank... Any comment?

Engine oil talk

Fubar20 TitanRev

I know you guys have your idea on how motor oil benefit the car. Here's my piece to chip in despite I'm not particular and have very little knowledge on engine oil. I've been driving several years, changing engine oil almost every 3 month, sometimes twice when I hit 3000 miles too soon. Due to cost of motor oil start increasing, I found I'm paying more and more on the vehicle maintenance, so I start to dig more info from magician. Helping to overhaul engine benefit the most in terms of technical knowledge and understand how motor oil affect engine performance.

Rule of thumb, buy engine oil with API stamp. Here's a link, please download and print a copy put inside your car. The next time when you wanna purchase motor oil, make sure you read the ratings whether its SN/SJ/SM/SL.

http://www.api.org/certifications/engineoi...2010_120210.pdf

With API ratings, you'll get an idea how these engine oil comply to your power unit. Your motor vehicle rely on the chemical inside the motor oil to survive friction. The viscosity only meant very little, but the API rating worth the most. Hence, when you use cap ayam motor oil, despite they put down 10w60, that does not mean the molecule can stand your car's 10.1:1 compressrion ratio with 400'c extreme heat during the ignition. Be it 10w100, it doesn't make any difference when the oil being channeled into the combustion chamber.

However, don't take my word as a whole. The viscosity does yield it's importance. For instance 10w40 multi-visco simply means 10 comes suffixed with W, meaning WINTER(not weight/watt as claim by others) for cold start viscosity. The 40 after W is hot viscosity. The front winter denote has lower figure, meaning the liquid has lower "beku" point. Sorry ran out of vocabulary. The hot visco higher denote a higher boiling point. You don't want oil to boil, just like your mommy cooking in the kitchen.

I've seen many horrible incident's while helping customer to do engine overhauling. Unsurprisingly, most of them having problem with their motor, they tend to miss their oil change quite often, sometimes up to few years did not change oil at all. Before dismantle an engine for overhaul, as I loosen the oil sum nut, I'll be extremely careful to not let oil spill on my hand. These burnt oil can irritate my skin and cause allergy. However, most of the time after the sum nut being pull off, there aren't any oil drip out. Even if there is, very little and very thick. Got once we unable to drain anything out from the sum, because those oil already turned grease. Can imagine how not to jammed the pistons?





Thinner hot viscosity oil does not mean you have less chance building up sludge, infact it's the opposite. Otften I ask magician why not fully synthetic as those expansive oil usually added cleaning agent, can last up to 6000 miles. The answer is simple, recycle the same oil in the engine can only make those oil turn into sludge. Debris and dirt to have more opportunity to form a bigger object between molecule, hence sludge start to build.



I used to worship 76 racing motor oil 10w40 for NASCAR, until my car start to emit white smoke and finally ended up with a full overhaul. Again, I did the overhaul by myself with assistance of magician to find that not much sludge built up, but the piston ring has been fully grounded off. Lesson learned as magician explain, usually racing motor oil does meant for racing. Those oil wouldn't last more than few thousand miles as it degrade faster than normal oil from the market. The dangerous part is, motor oil should form a film of coating on engine parts, but the degraded oil does not. It will be fully drained to the sump. Believe it or not, your engine life were shorten each time you crank start it, not when you taking it to the redline(provided the redline figure is properly balanced on your crankcase).

From the above little knowledge I gained from magician, I've been practicing frequent oil change. For your information, VTEC oil is rated SAE10w30 have no problem running at 8krpm.

See, reason why X1R has to be avoided.

In undocumented cases, cars running on NGV (BLM taxi primarily) also suffers from heavy sludge build up after using X1R.

Terrible sludge edi build up in turbocharged engine, i wonder how it works in the "NASA rocket" as their advertisement claimed.

for NA engine it is still OK. But better just avoid it all together.

for CFE engine, since it is turbocharged, the temperature inside gets hotter than usual NA engine, hence the heat accelerated the breakdown of X1R and that turns into massive pile of sludge.

Still using. Managed to exchange it. It still judders (but way less) when the screen is not very wet but dirty or when the screen is wet but clean. Otherwise it doesn't judder at all if it's respectably wet and dirty. I haven't washed my car for quite some time.

anyone already add atf cooler? any positive feedback..e.g smooth gear change..engine temp others? plan to install.

u ingat ATF cooler byk murah ar.. btw its not necessary to use ATF cooler if u not always racing...
insulfelx less thn 100... 

atf cooler the smaller size already cost ard 350-450 depend brand... larger capacity is 600++ onwards if not mistaken...maybe unker daivd know the price..

my fish pasang atf cooler smaller size + labour + top-up ATF = nearly 500 bucks...

my fish pasang the atf cooler while my fish is already 7 years old as i push my fish damn hard... sumtimes rev till max and takut gb will overheated as the gb sumtimes will delay shifting... after pasang, smooth ride but later this year gb TC gone wrg liao...

dun la lidat..those ppl baru beli SV c all this..no good..morale down..

Go back to ur thread lah, you hamsup fella. 

knowledge is power. ksian to that girl ma. she just ok ok at the SC and then go bising at others too mahal... wtf. x1r oso take everytime go service soo rich yet so bising... i give her what shit u wrote as a guide.

You want gear change feeling, just switch on SAT, shift shock til you hngghh. New Honda City CVT pun tade this feature

You see, Proton memang jaga all their customers.

but then SAT got , so what point of CVT? haha...why all whistling... me unwanted here a?
