如果你有油泄漏到冷却水,然后盖垫圈已经坏
您可以通过在发动机冷却后沿着道路行驶来确认这一点,将热量调低并听着刺耳的声音,就像某处水中有空气。这清楚地表明空气正在从腔室泄漏到冷却液中,并通过加热器芯。这可能就是为什么您的热空气不再那么热的原因
它可能太小而无法通过压缩测试注意到,或者它可能是一个自满的机械师,看到1-3个圆柱体很好,一个只掉了一根头发就掉了,但是没关系,它可能只会在您当车辆不在怠速转弯处时,沿着道路行驶
更换汽缸垫很简单,但这需要大约10个小时的工作,有时甚至可能需要从发动机上拆下电动机。这是一个粗略的展望,可能并不适合您的汽车类型。但这给你一个总体思路
1. Disconnect the negative battery cable
2. Drain the cooling system (coolant)
3. Remove the Intake manifold
4. Remove the throttle body
5. Remove the PCV valve
6. Remove the air filter
7. Remove the alternator
8. Remove the spark plug wires
9. Remove the spark Plugs
10. Remove the Distributor cap ( or coil pack )
11. Remove the radiator fan
12. Remove the coolant pump
13. Relieve the fuel pressure ( pull the relay in the junction box and start the car 3 times )
14. Remove the fuel line
15. Remove the fuel injectors
16. Remove the exhaust manifolds
17. Remove the head cover
18. Remove the timing chain ( Mark chain to sprocket with a ink pen )
19. Remove the timing chain Tensioner
20. Remove the head bolts In a random order when the engine Is cold ( Failure to do so when the engine is cold may result in a warped head )
21. Remove each head bolt by 1/4 of a turn before removing ( New head bolts required on Installation )
22. Use a pry bar at the corners of the Cylinder head-to-engine block ( Do not pry between the cylinder head and the engine )
23. When Installing place the engine at Top Dead center, by aligning the notch in the crankshaft pulley with the TDC Indicator
24. When Installing - Inspect all hoses and replace all gaskets
25. When Installing - tighten head bolts in s specific sequence such as this
吹头垫片的其他症状
我并不是要吓you您,但是由于天冷了,密封件已经缩了一点,为通入冷却液的通道打开了一个通道,(只有在踩油门时才有可能发生)如果伸出来直到夏天,密封件可能会膨胀并填满间隙……诸如此类的泄漏会导致发动机缸体破裂,因为水(冷却剂)进入燃烧,Is使用机油消散热量并润滑零件,水和冷却剂引起腐蚀。
但是在您花1000美元购买机械师或50-300美元购买一堆新垫片之前,请记住,它们还会为小头垫片泄漏的油制定停止泄漏公式
这是一个头部垫圈,但请确保在更换时清除所有碳的头部,没有理由取消。它消除了任何爆震声,并使您的发动机总体上令人满意
