03 Bora 1 8 valve chamber pads leakage

The car time is quite long.

Tell you the cause of the oil leak in the car:

More than 90% of the car oil leakage is caused by the corrosion and aging of the oil seal, over time the rubber seal will lose the plasticizer, the consequence is that the oil seal begins to shrink and harden and lose elasticity, serious and even broken, oil leakage problem is inevitable. Car problems can be used without dismantling and repair, there is no damage to the car, the use of Marty DS can be, Marty DS contains a highly efficient plasticizer, which can penetrate into the seal or be absorbed by the seal, and then the seal will re-expand to restore elasticity, and it is acting on all rubber seals are not a single oil seal, fundamentally solve the problem of oil leakage, and can also inhibit the recurrence of oil leakage problems.

Hello! Replace the valve cover pads, as well as the chain tensioner gaskets!

Hope it helps! Have a nice ride! [Car questions, ask the car master.] 4S shop professional technician, 10 minutes to solve. 】

The exhaust pipe is blocked, and the pressure in the engine compartment is not released; Uneven screw pressure during assembly; The screw pressure is too high, which deforms the valve chamber cover. Get it repaired as soon as possible. Hope.

Hello, it should be caused by the aging of the gasket, replace the gasket. Have a great trip. If I can help you, please set it to, thank you.

Replace the valve chamber cover pads.

Summary. That is, there will be oil leakage in the valve chamber cover gasket on the engine, and there will be this after the replacement, and this need to check the waste valve to see if there is a problem, if the waste valve is blocked by it, the exhaust gas pressure in the engine is relatively large, and it will also lead to oil leakage in this position. If there is no problem with this wastevalve inspection, it is necessary to continue to replace the valve chamber cover gasket.

It is also possible that the quality of this replacement is not good, or that this valve is in this position, and this is not very smooth.

Hello, happy to answer your questions.

Hello, I am helping you sort out the answer to the question, please wait a while Oh is that the valve chamber cover gasket on the engine will leak oil, and there will be this need to check the waste valve after replacement to see if there is a problem, if the exhaust valve has a problem blocking it, the exhaust gas pressure in the engine is relatively large, and it will also lead to the phenomenon of oil leakage in this position. If there is no problem with this wastevalve inspection, it is necessary to continue to change the valve chamber cover pad. It is also possible that the quality of this replacement is not good, or the valve is in this position, and this is not very smooth.

I have changed it 5-6 times, is there a problem with the cover?

Deformation. Check this wastevalve, there is a collapse and there may be a problem with the wastegas valve blocked. If there is no problem, it is possible that the valve cover may be deformed.

Good. Good.

First, check the exterior for oil leaks.

Pay special attention to whether there is oil leakage at the oil seals at the front and rear ends of the crankshaft. Oil leakage at the front end of the crankshaft can be caused by broken or damaged oil seals at the front end of the crankshaft, aging or worn contact surfaces between the crankshaft pulley and the oil seal. The oil seal at the rear end of the crankshaft is broken and damaged, or the oil return hole of the rear main bearing cover is too small, and the oil return is blocked, which will cause oil leakage at the rear end of the crankshaft.

In addition, attention should be paid to whether the rear end of the camshaft oil seal is leaking. The oil seal should be replaced in time if it is aging, broken and leaking. In addition, it is necessary to check whether there is leakage in each part of the engine lubrication system.

If there is oil leakage at the front and rear oil seals.

Even the front and rear cylinder head covers, front and rear valve lifter chambers, oil filters, oil pan gaskets and other organic oil seepage, but can not find obvious oil leakage, should check the crankcase ventilation device, clean the crankcase ventilation duct, especially check whether the PCV valve due to carbon deposition and gelation stagnation caused by poor work. Poor ventilation of the crankcase is likely to lead to an increase in pressure in the crankcase, resulting in multiple oil leaks.

If the joints of the oil filter and some oil lines are still leaking after being tightened, attention should be paid to check whether the oil pressure is too high and whether the oil pressure limiting valve is not working well.

Hello, oil leakage will consume oil abnormally, resulting in a rapid reduction of oil, it is recommended to replace the valve chamber cover gasket, this thing is not expensive.
