Balance Shaft Problem

Engine Model : 1AZ engine 2.4cc

Car Model : Estima, Alphard, Vellfire, Harrier, Camry all 2.4cc

Signal : Early morning engine start got “kolo, kolo” sound, but after a few minutes then no sound already. Afternoon and evening then ok

Checking : Remove fan belt then start the engine in the morning, if got sound then confirm is balance shaft problem

Solution : Remove the oil pan, change the balance shaft, flushing the engine to remove fiber powder.

Reason : This engine balance shaft gear is made by fiber “green color” to protect crankshaft worn out. And this fiber has its a life spent.

Effect Of No Change : If you don’t change and let it go. The fiber powder might block the oil pump net, causing the oil cannot pump up to the cylinder head. Then change the engine eventually.

Toyota Vellfire/ Estima /Alphard Engine Mounting Vibration

Engine mounts are made with a rubber material so that there is no direct metal-to-metal contact between the engine and the car body.

To further dampen the vibration, some engine mounts are filled with liquid. A liquid-filled engine mount works like a shock absorber.

How long can an engine mount last? In some cars, engine mounts can last the life of the vehicle. We see the most of the problems with engine mounts starting to show in 5-7 year-old vehicles.

Engine Mounting Problem

The most common problem with the engine mount is when the rubber part breaks or separates or when liquid starts leaking out of the liquid-filled mount.

Common symptoms of a failed engine mount is the increase in engine noise and vibration felt inside the car.
