Yes.. This is how IAFM technology work.. Long-short intake manifold. But in term of pick up, saga blm really leak abit of power due of campro.

Proton Saga BLM = Problem with the intake manifold. But it can be claimed. The intake manifold will cause some noise and the idling is not good. Not all saga BLM have such problem. But the common problem, the power window switch.

So far what I see my customer claimed is intake manifold, steering rack (The steering rack will leak power steering fluid), rear wheel bearing (First batch of saga blm. the wheel bearing is not fit while I don't know why proton still using it and cause burn out) and last, power window switch. This is the thing normally I help customer to claimed at my workshop. And, got 1 batch of saga blm auto which have overheat problem. Only happen on Auto cause of a cooling host problem.

Proton Persona = High risk of overheat problem. While I have two customers having overheat problem with their car before 10k. We claimed the cylinder head for them, but the temperature still not normal. Temperature will increase and drop not stable. Another problem is, front and back wheel bearing will spoiled due to water store inside. Last, for the drum brake behind. Having sound when during braking. Not forget, some batch of persona front having 'tak tak' sound when at uneven road but this problem can be solve.

And the most common for Proton Saga BLM and Proton persona is 'rat' sound at the back. Because of the rear seat..
