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

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.

IT must be the misalignment of the conrod and conrod cap...

It's always an issue of QUANTITY vs. QUALITY. When will these people understand! :frown:
BTW, aren't the piston oil-lines for lubrication? I mean, the lubricant serves a cooling purpose too, right?
But then again, with assembly quality like that... :frown:
