try whack urs and see lo...if broken adi time for b18c...

Camshaft breaking? Hahaha...I dare say that its not the mechs fault. It's Proton's fault...maybe the cam came from a bad batch. I've seen more expensive cams from Tomei, Today and JUN breaking as well. Factory error one....youre just unlucky

if break when over revving, yes manufacturer's fault...

but if broken during engine overhaul (engine dismantle process), its mechanic's fault...

gehgeh.. we'll see

some bloody mechanic purposely spoil it or cause new problem to earn a quick buck. thats my personal experience lar.... i quickly scold the fella why you break my etc etc then look for the boss straight away.
settle on the spot.

CPS is on went 3.8k RPM so no need ram high2 to get other performance "save fuel"

hey guys,

i still don't understand why Gen2 CPS/Waja CPS engages on 3800rpm,
while Neo CPS engages on 4400rpm ??

i thought all are same engine?
how come CPS engages is difference ?

this one u ask proton lo...

wanna ask whats the exhaust pipe size for campro 1.3 and 1.6?
is the size same across iafm,cps and camtakpro?

My friends Waja Campro stock pipe size is 2" if I'm not mistaken. I think the 1.3 model should be around 1.5"

How to get rid of burning smell when every-time doing high revv?

Car model : 08' Gen2 CPS Manual.

i think normal kua...my plain campro also sometimes do have burning smell when rev....but recently i switch to fully-syn dont have wor...

inner diameter or outer diameter??

my fren advice me do frequent high revv to get rid of the smell

i would try Motul Fully-Syn engine oil on my next service...

one possibility is that since the Gen2/Waja is heavier than the Neo, it needs power to come in sooner, hence 3800rpm, so proton set it that way

haha....frequent high rev...manual boleh..la...auto abit takut... .....how much is the motul fully-syn???....wad grade??

Auto car one week doing few round high revv i guess still acceptable de..

you can refer : HERE

Btw, my 4500KM mileage Persona automatic now having this "tak tak tak" sound (not very loud though) during idle after start up. But it disappears after a while. Is that the sign of a failing IAFM module? I can't really tell because i am used to a noisy timing chain based MyVi 1.3 engine driven for almost 4 years.


Another question:

I am sure many heard and read that the horror stories of crankshaft breaking on earlier Campro engines for those loving high revs all the time. What about the current Campro engines? Have Proton rectified this matter? Any happenings still?


Review:

After few months of driving my new Persona automatic with IAFM Campro 1.6 DOHC engine... i find that the power delivery at speeds excess of 90kmh and above are quite decent. Reaching 160, 180kmh was quite easy during cruising on highway. Initial stand still pickup wise is a tad heavy and slow (can this be improved by means of changing to aftermarket headers?).

But since its just a regular old tech DOHC engine (Campro name that means nothing at all...other than just another name for an engine) without variable valve timing etc.... i find that going uphill is slightly a struggle whereby i need to press on the accelerator much more compared to a car with vvt / variable valves timing etc. I am used to driving MyVi with dvvt / vvt engine so i can really tell the difference between a non vvt and vvt engine...

Good Day,
The basic Campro engine coded as S4PH is a basic DOHC 16-valve 1.6 L engine that produces 110 bhp (82 kW) @ 6,000 rpm of power and 148 N·m (109 ft·lbf) of torque. This is the engine that powers the Proton Gen-2. The S4PH engine can be fitted with Cam Profile Switching (CPS) and Variable Inlet Manifold (VIM) technology. Besides this 1.6 Litre engine, Proton has produced the 1.3 Litre version of the Campro engine.

Even though the S4PH engine seems to be quite powerful at higher revs, its performance is reportedly sluggish at lower revs and this is proven by driving the Gen-2 uphill where drivers who drive the manual transmission version have to shift a lot between 2nd gear and 3rd gear. This is due to its torque dip in the crucial 2,000 ~ 3,000 rpm operating range, where the torque actually decreases before picking up back to the maximum torque at 4,000 rpm. This torque characteristic can be clearly seen in manufacturer published engine performance curves.[1]

Another engine option for the basic DOHC engine is a 1.3L engine coded as S4PE. The S4PE engine produces 94 bhp (70 kW) @ 6,000 rpm and the torque of 120 N·m (89 ft·lbf) @ 4,000 rpm, which is more powerful than the other 1.3L rivals, even with variable valve timing technology, it also (like its bigger brother) displays a torque dip at typical engine speeds of 2,000 to 3,000 rpm.

The bore x stroke dimensions for both engines are as follows:-

S4PH (1.6L): 76 x 88 mm, resulting the displacement of 1598 cc.
S4PE (1.3L): 76 x 73.4 mm, resulting the displacement of 1332 cc.

Replacing after market is not necessary improving your torque and pick up. The engine is design differently. Just accelarate smoothly in the begining and once reaching is optimum speed , then you really feeling the engine power and roaring.

I been driving Proton Waja Campro 1.6E, year 2007. Firstly, i do had the same impression but later i felt once it reach 60 km/h or 3rd gear you can notice the engine power.

I think my 4650KM mileage old Persona automatic is having this "tak tak tak" engine sound already... what the happen?!
