i also feel wanna change to semi-syn engine oil next, but i worried the engine will "makan minyak hitam" even more because semi-syn is thinner (easier to leak away into wrong places).

when u wanna fix it?
easy to open the bumper la. 2 nuts under the fender,1-3 under the grill & 1 under the headlamp for each side.
do like this

Plan to change my lubricant for my wira 1.5GLI clocked at 110k soon.

I was used 15W50 before, if i change to use 15W40 or 10W40. Do i need a engine flush?

oh speaking of this, on sunday, i "sealed" back my drilled airbox, just for comparison's sake.
just butt-feeling, but on hot afternoons (eg lunch hour) the car feels smoother compared to drilled.
but at night or early morning (going work), drilled is definately better feeling.
i think due to hot air/cold air?    will keep it this way maybe for 1-2 weeks more.
btw mike, if u wanna seal it back, just stick those heat-resistant tape lor.
but make sure is stick on outside of the airbox, not the inside! inside got risk...

add: guys, what is actual name for doing "mudgard" ah? u know wat i mean rite? patching of car body, sanding it smooth, etc.
one more question, where can buy this substance? coz i wanna DIY patch my skirting and lips, some parts chipped, not nice.
thought to patch before i respray (DIY also hehe) thanks

In order to get power output, you need to dyno~~

Anyway, in a chart, you just see the power, torque and the AF ratio whether lean or rich, the AF ratio determines your overall performance throughout the rev range

u better check that ur brake system is not leaking...later no brake pressure...u ?????...dont wanna say here...takut...

Didn't get to dyno.....1 pink SG EVO X was there tuning MOTEC and dyno runs and something bad happened to it
Probably something burned....so end up the whole day screwed because of it

alvinz...grind valve too...and skim ur head...then a new gasket...top overhaul...

remember do port n polish also
