Auto Parts Valve guide 4749397 For Iveco Daily Fiat Ducato 2.8 A
The Valve Guide supports the intake/exhaust valve stem, stabilizes the valve attitude and allows heat to escape to the cylinder head side, hence, it needs to be durable and made with great precision.If the clearance is too large or the valve guides are worn out-oftrue, conical or flared, they must be replaced. For valves with a skirt diameter of less than 8 mm in particular, knocked out valve guides have a big impact.
