Why campro engines fail on crank!!! Campro 1.6 vs 4g92p

[mark_15]

yup...mMmMm.....but 4 wut...campro piston also not that high comp...huhu....better is use campro 1.3 piston..higher dome compare 2 sudu 1.6 campro piston..

 

[artworkz]

no lah, i jz waste my time to do match campro piston to 4g18 conrod. c can or not oni. i do wen 4 years ago .

The first version pistons are Bullet type. Quite flat though, but i think got CR10:1. No valve pocket.

good write up bro... :top:

 

[artworkz]

ohh, gt two version ah...long time no do silly thing ord.den last time i use is highcompression tat 1 lol. but tat waja not diffrent after high compresion.

any proton employees here..pls dont shoot anybody if ur mad reading this

normal use is ok...if gasak, then sorry...

agreed..i hv a piece at home waja campro 1.6..been using it for 3 years alrdy..so far it did it's job fine..but this engine is not for heavy duty..if u gasak then it won't last long..to me the most important thing is the service time punctuality..

speed2horizon,
thanks for the info bro..with ur kind of writing is enough to convince people not to buy Waja Campro

Sorry if I am offending. But I really don;t mean it. Just wanna share what I see.

y must not buy waja campro.....its a good car wut...hehe

Acttually nothing wrong with WAJA Campro. Engine not to say problem la... Just that the design of the engine seems less durable.

But 1 thing I cannot tahan is the rear lights design.... Macam taaaahhhiii

 

[mark_15]

haha..that i got 2 agree wit u...huhuh....the old 1 is so much better...haha...but thank God la..my car 4 2 3 years edi in the drag scence but got no prob at all....real lasting my campro...

 

[Enslaved]

The campro is not slow once up to speed on the high end..

haha understood bro..no hard feelings taken..in fact posted all the findings here had made most of us aware of this..even most of the Campro owners didn't know this

The hole in the conrod bearing is not for oil entry. Almost all (if not all) crank bearings and conrod bearings oil supply is from the crank shaft it self. The hole is mainly for piston cooling.

Most aftermarket conrod do not have the oil hole. They can work without it..

The holes under the piston are for oil drainage from the piston oil scraper rings. It is never intended for oil supply to the rings..

I suspect what cause premature failure of the conrod bearing is the conrod and the conrod cap are not aligned properly.. proton bad machine work...

Thanks for the information.. Appreciated the input.

Urm... If u realize, some aftermarket conrod also have oil lines fromt the crank all the way to the piston pin align right at the center of the conrod shaft. Cooling also.

And for every where the oils went through in a conrod and pistons, they are used as cooling and also lubrication.

And the improper conrod cap and conrod alignment leads to the crank failure where the protuded part of the conrod scraps along the conrod mount on the crank.

Being in the diecasting and molding industry for over 3 years, I know that die casting is loosing money due to the cost of die, aluminum melting machine, maintenance, fuels and remelting of the returns. But machining work are gaining. Machining work cost alot of money.

So, by saving the cost of machining, it simply means they save alot. Imagine 10,000 unit car/year. You'll have 40,000 unit of conrod and 30% spare parts in the market.

52,000 units of conrod produced for 10,000 car. To save RM2 in every conrod, they saved RM104,000/10,000 cars produced. But mana pergi..? Oppss... Sorry... Spoken too much.
