Information
Exhaust valve guide set. Outlet, 1st Oversize
This is a set of four OE Match exhaust valve guides engineered to replace the worn or original guides in the Porsche 914 air-cooled engine. This is a first-oversize exhaust guide intended to fit cylinder heads that may have experienced wear or require an oversize fit during an engine rebuild. Supplied as a complete set of 4, this kit is ideal for a full cylinder head rebuild or valve job.
SET OF 4
Fits:
Porsche 914-1,7/1,8V
Porsche 914-1,8
Diagram ref no 15
Exhaust valve guides serve several key functions in the overhead valve train:
• Support and align the exhaust valve stems, ensuring they travel straight within the head.
• Maintain correct clearances between the valve stem and guide for proper sealing and combustion efficiency.
• Help transfer heat away from the hot exhaust valve stem into the cylinder head casting.
• Protect valve stems and seats from wear due to excessive lateral movement.
This set of four valve guides ensures that all exhaust valves on the 914’s four-cylinder engine have correct, matched guidance for dependable operation.
This OE Match set matches Porsche factory dimensions and is ideal for full head rebuilds, valve seat replacements or anytime guides show wear.
Function
• Valve Alignment: Keeps the exhaust valve traveling straight for proper valve seat engagement and sealing.
• Wear Control: Reduces lateral valve stem movement that would otherwise accelerate wear on the valve and seat.
• Heat Dissipation: Helps carry heat from the hot exhaust valve stem into the cylinder head.
• Rebuild Support: Oversize fit for cylinder heads that have been reamed or show wear.
Valve guides wear over time due to high heat, friction, and repeated motion. Worn guides can result in:
• Excessive oil entering the combustion chamber
• Poor compression, rough idle or power loss
• Increased valve stem wear Higher oil consumption and visible exhaust smoke
Installing a correct OE Match valve guide restores proper valve stem alignment, improves sealing and performance, and supports a longer engine life especially crucial during a rebuild or head service.
Replace the exhaust valve guide if you notice:
• Blue smoke indicating oil burning
• Low compression in exhaust valve tests
• Rough running or poor idle quality
• Worn valve stems or seats seen during teardown
• During head rebuild or valve seat work

发动机缸盖排气阀。Varioram发动机之前的车型
OE Match排气阀是一款精密发动机部件，专为配备早期3.6升发动机的保时捷911（993）Carrera车型设计。它安装在气缸盖内，是气门机构的一部分，负责控制废气从燃烧室到排气系统的流动。
单独出售，每辆车需要6个。
适用：
保时捷 993 C2 / C4 3.6L 1993 - 1995
* 发动机型号：M64.05 / M64.06 / M64.07 / M64.08
图示编号 10
零件编号为 99310541901 的 OE Match 版本专为早期 Carrera 车型上使用的 Varioram 之前的保时捷 993 发动机而设计。它采用正确的阀杆直径、阀头尺寸和材料规格，能够承受高性能风冷发动机中遇到的极端温度和应力。
排气阀控制燃烧室内的废气排放。当凸轮轴在正确的时间打开排气阀时，废气便会排出气缸并进入排气系统，为下一个进气循环做好准备。
保持阀门正常运转对于高效燃烧、发动机动力和可靠运行至关重要。
排气阀在极高的温度和持续的机械应力下工作。随着时间的推移，它们可能会磨损、变形或积碳，从而导致压缩损失、发动机性能下降或气门机构噪音。在发动机保养或大修期间更换磨损的排气阀，可确保良好的燃烧密封和可靠的发动机运行。
如果发现以下情况，请考虑更换排气阀：
•压缩损失或发动机动力不足
•气门机构噪音过大
•烧蚀或磨损的阀门表面
•在气缸盖大修或发动机大修期间
