oic, hmmm, next time if my car got tappet noise I sure double check on this also.

Many foreman told me if wanna play 4G9X DOHC engine, dun stingy on engine oil maintenance, when time come, just change it, no need use expensive engine oil but must change ON TIME (advisable every 4000km), many of them comment alot of their customer got a lot budget modify here and there but never bother service their car, end up when tappet noise come ask for service, they have the tools to service the hydrolic tappets but mostly customer have to change one set of 16 tappets, cause the carbon built up from engine oil already cause wear and tear for this sensitive tappets, which cause over RM1000 because it is very hard to determine which tappet koyak, end up most of the customer try their luck get another head for transplant.

yah i agree 100%.... last time when i newly transplant my engine.. the tappet sound was to the max... fucking irritating n embarassing... 1 shop quote me change all 16 of them.. 80/90per piece of not mistaken.... luckily i found a 4G91 textbook ...ALVIN SIFU dat is... after his advise my problem solved immediately... save my $$$$...

If tappet noise come, not only irritating, but also lose of power.

skyline_maniac, you better fast fast change engine oil and see, if cannot solved then no choice you have to replace tappets, just pending your other mod project first lor

solving tappet problems IMPORTANT notice:
1. DON'T use additive... trust me, it'll make things WORSE!
2. DON'T use Shell engine oil... of all my years experience, Shell oil makes tappet noises louder
3. ALWAYS service on time!
4. ALWAYS check to see if got enuff black oil... top up if necessary


Solutions that nobody listens to:
1.DON'T alwiz high rev engine... obviously nobody listens to this


Recommended oils known to help reduce tappet sounds:
1. Magnatec semi synthetic
2. Penzoil normal oil (the yellow bottle wan)


I'm using Endless engine oil... doesn't reduce tappet noises as much as Magnatec does for my 4G91... but heck la... i find Endless oil to be smoother.


Other alternatives:
1. Service tappets... i know somewhere that does it for 100+ (forgot exact price)
2. Change all 16 tappets (or those loose ones only... depending on condition)
3. U can always 'try' to flush your engine before ur next oil change... it didn't work for me though... but it did work for some of my friends with minor tappet sounds (mine was pretty major back then... but i did a full tappet service and replaced the loose ones).
**Brand new tappets costs around 90 per piece


Advice for tappet noise prevention:
1. ALWAYS CHECK ENGINE OIL!! (very important... once the noise starts, it won't stop)
2. Don't always rev here rev there lar... or stay at high revs long long

**Reason why checking engine oil is very important is because if there isn't enuff engine oil, the tappet sounds will arrise... and by then, if u fast fast tambah oil also already too late, coz' once the sound starts, it won't stop.



Hope this info helps everyone with tappet problems. =)

SIFU'S advise... save it yo...

Agree, my first tappet noise come after I rev to test top speed on the way go KLIA, so, to all 4G91 member, we should put alvin advice in mind, dun high rev our engine.

Party, my birthday last time u neve wish me pon.. hahahaha.. pilih kasih la u..

actually there is a way to test the lash adjuster, but for sure our local mechanic does not have the actual machine to test / calibrate it la.. so the other way is submerging it in diesel over nite then press2 inside the lash adjuster hole to relieve any sticky areas or any residue that is blocking its function.. if it is too loose then have to chage la.. last time when my timing belt putus i did the servicing 1 time.. now still ok.. hehehe..

hi there bro... ISC is the IDLE SWITCH CONTROL... which located at the throttle body...
i face this problem also b4... now using FICD to solve it... abt the manifold, i read in PMC dat it better to use GSR manifold cos the route is shorter... but donno abt he effect, cos im using stock manifold rebored to 60mm...abt the hotbit extractor 1.6 .... our 4g91 taiko alvin was using it b4 but dunno wheather 1.6 or 1.8 punya... mine is 93 cap ayam 1...

In general modding, the shorter intake manifold will shift power band to lower RPM, extremely useful for turbo car to assist turbin spool up.. longer intake manifold will shift ur powerband to higher RPM thus giving extra "breath".. its like on the Mivec for higher RPM utilization.. so u choose what u like.. only thing is the GSR ones are bigger port so matching throtle body and ported head will be more appropriate..

you wrong, longer intake manifold for better low end, shorther intake manifold for better response on high end, MIVEC have longer intake manifold to compesate it low end torque
