It seems to be surrounding that square rusty cover right below the hose circled in green (is this the timing cover)?Īfter 1 weeks of in town driving, I clearly see oil seeping out to the bolt pointed by the arrow. I was hoping it was the power steering fluid spilling over, so I cleaned area. But all the read circled areas are covered with black oil (completely black):Īlso, when I was working on the transmission cooler lines and fluid change, the areas below these areas are also covered in black oil. Now, I realized that I may have the dreaded timing cover leak: I should haven taken a picture before I cleaned the area with 4 cans of carb cleaner - because I wanted to make sure there is oil leak. While a front cover oil leak repair can seem costly, an engine replacement cost is far higher and may be required if the oil leak is ignored.I think I really got a bad deal with this truck (bought it in Jan): first the power steering fluid is mysteriously over filled and spilling all over the place then I found a big transmission fluid leak, turns out to be the transmission cooler outlet line has rusted through, so I had to replace both cooler lines and change the fluid (only about 1 qrt old fluid came out so my transmission could have blown up if I hadn't noticed the leak for another two months). If you have noticed an oil leak under your vehicle you should have it rectified as soon as possible to keep your engine running as smoothly. If the engine oil level inside your engine is low, oil overheating and premature failure of internal components can result. How important is repairing a front cover oil leak? If there is an oil leak from behind this cover, the timing belt will need to be replaced and the camshaft and crankshaft seals inspected for leaks The front cover of a vehicle fitted with a timing belt is usually made of plastic so does not require replacing unless damage has occurred.If this is the case, there will be many components that need to be replaced during the repair, such as bolts and fluids Depending on the type of vehicle you drive, the engine may need to be removed to allow access to the front cover of the engine.The vehicle will be test driven to ensure repair has been carried out successfully.The engine will be started and brought up to operating temperature to check for any leaks.The engine will be reassembled and filled with fresh coolant and engine oil.A new gasket will be applied to the front cover and the cover refitted with new seals as needed.The old gasket will be removed from the engine mating surface and the front cover inspected for any damage.The engine will be disassembled to allow front cover removal.The engine oil and coolant will be drained from the engine.How is a front cover oil leak repair performed? Oil smell or smoke coming from under the bonnet.It is highly unusual for the cover itself to leak but if this is the cause, a complete cover replacement will be needed. If an oil leak is present, replacement of the gasket material is the only way to rectify this problem. The gasket that seals the front cover to the engine is made up either of metal with rubber seals, or a silicone-based sealant known as RTV. Repairs can start from $400 and increase to $1500 and above, depending on the vehicle and engine fitted. Unfortunately, having a front cover oil leak repaired can be costly as the front of the engine must be disassembled to remove the cover. When this happens, it's time to have the gasket replaced. Over time, these gaskets can fail and oil can leak out from where the front cover mounts to the engine. The front cover is usually made of metal and is sealed to the engine using either liquid gasket or a pressed metal gasket with rubber seals to prevent oil and coolant leaks. It also allows the engine oil to lubricate and cool the timing chain components. The front engine cover, also known as the timing cover or timing case, is designed to protect the timing chain/s and tensioners on the front of the engine. How much does a front cover oil leak repair cost?
