The rear differential controls the rear pair of wheels so they can rotate at different speeds, which allows your vehicle to travel smoothly and keep traction on the road. If you have...
Oil is one of the most important parts of any engine due to the lubrication that it can provide. The internal parts of the engine need a lot of lubrication in...
Keeping a car running at peak condition is a lot harder that most people think. The engine of a car is a very complicated piece of machinery that has just the...
There are a number of gaskets on an engine and each of them performs a specific purpose. For most car owners, their gaskets are not something that they think about...
Maintaining a car is a bit easier said than done to all of the parts that are contained within your engine. One of the things that helps to keep the parts...
Your exhaust manifold requires a seal between the cylinder head and the exhaust manifold. This seal is called the exhaust manifold gasket, and is an incredibly hard-working part. The exhaust manifold...
On your model, it probably takes around 4 hours to replace both the upper and lower intake manifold gaskets but if you have rear A/C it is somewhat longer. A gasket kit is necessary because other gasketed parts are removed...
You can get an exact quote by entering your year, make and model at YourMechanic's oil pan gasket replacement service page. To give you an approximation though, the required hours are probably in the range of 8 to 12 hours,...
Hello, thank you for writing in. The oil pan gasket can be tricky to replace. Quoting an exact price for this service can also be tricky. Removing the oil pan to access the gasket is the hardest part, and can...
If you have a valve cover leaking oil onto the spark plugs then it can cause a misfire. This does not mean the leaks are the cause but a possible cause. I would recommend having a mechanic like one from...
Hello, thank you for writing in. An oil leak like this can be tricky. First know that the oil pan, by design, is the lowest component in the oil system, so that gravity will collect the oil in the pan...
If you have a small vacuum leak at the intake manifold then it may be okay to drive it until you get it fixed, but may have running issues or check engine light on. If the intake is leaking coolant...
As long as the valve cover is not distorted or cracked, it is re-used. Valve covers can be verified for "flatness" to determine if the sealing surface is distorted. You are asking a good question because IF the sealing surface...
The cover (or "housing") is not removed. You merely disconnect the timing chain housing at the camshaft housing, but do not remove it from the vehicle. There are specific torque values required on all the fasteners so be sure to...
Hello, thank you for writing in. Simply pulling the mass airflow sensor is not a good enough test. You will want to test it with a multimeter to get an accurate reading on how it is working. The symptoms you...
Hello - normally, no. The valve cover gasket can be replaced without getting into the timing belt components. Having said that, replacing the valve cover gasket is a great opportunity to make sure the cam seal isn't leaking oil onto...
Hello. The piece you are referring to is called a valve cover gasket. It sits between the top of the engine as if a piece of cheese would between a bun and a patty to keep the oil from leaking....
Hi there - a leaking valve cover gasket can cause misfires if spark plugs, plug wires/boots or coils get wet with oil, and there is a risk of fire if oil leaks onto the exhaust manifold. So it makes good...
Using gasket maker in place of an oil pan gasket works sometimes. However, what I recommend is using a the actual cork/rubber gasket with a thin coat of The Right Stuff brand gasket sealant applied to both the engine block...
Oil pan and/or pan gasket replacement on this vehicle has to be performed with the Factory Service Manual in hand. There are just simply too many steps, and too much detail to re-count it all here, not to mention the...
Anytime you have an oil you should have the repairs needed as soon as possible. An oil leak getting on the hot exhaust can cause an increase risk of fire and also leaking oil can damage components and wiring harnesses....
Hi there - the QR25DE engine was introduced by Nissan in 2000, and was used in the following models: Vehicle applications: 1999-2003 Nissan Bassara- 165 hp (123 kW) 2001–2005 Nissan Serena C24- 158 hp (118 kW) 2001-2007 Nissan X-Trail T30...
Hello, thank you for writing in. While there are several pathways for oil to get to the spark plugs, the most common is the valve cover gasket, and the o-rings located in the spark plug wells. One or both of...
The felt seal would be used inside the front timing cover in front of the seal as an addition to reduce the amount of seal leakage when the engine is not running and to help keep out excess dirt for...
The re-designed gasket (Fel-Pro, for example, in the aftermarket) for the lower intake manifold on this engine, and the revised installation procedure, provide a 100% effective resolution to the notorious leak issue that you are referring to. With regard to...
The gasket itself is less than $50 and it looks like if you have the N52 engine, it could take in the neighborhood of 8 hours (roughly) to remove and replace. There is quite a bit of disassembly; for example,...
