That knocking may be permanent internal damage due to low oil or a bearing. If u still have the knocking w oil full, get ready for some serious engine work. Think about how much u want to invest. Fixing the seal is 1 issue but u may have 2 very expensive issues. Rebuilt motor would be my suggestion. Good luck

Big job....
You have to drop the motor and tranny out as one unit. It comes out the bottom.
Once you have it out, it's pretty straight forward, seperate the two, change the seal, reassenble, put the power unit (motor and tranny) back into the car.

That's the simplified version of it, but that the overall idea of how you have to do it.
If you need additional information, please let me know.

Well those are hard to do it by yourself so I suggest you go to your auto repair shop and have them do it. Of course you can go to different shops so you can see the difference in pricing if any.

SOURCE: 94' toyota 4runner rear differential seal

1st, check to see ifthe vent is plugged on the Differental????? This will make the oil to come out when the oil heats up amd makes gases & pressure. The gases & pressure has to go somewhere!!!! Did the person put a new Crush sleeve, to take the slack out of the pinion, which will makes to pinion move from side to side. Replacing it is no problem. Just time! Gear oil, Seal, Gasket, & Crush sleeve. Place everything on the ground in the order that you take it off. Also check upper & lower bearing & races to see if they need to be replaced. This will also make slack, which will mess up your seal, and star leaking again. Good luck,and take your time.

SOURCE: oil leaking from rear main seal, how hard is this

Replacing the rear main seal is kind of a long one. It involves seperating the motor and trans. Depending if it is manual or auto,would weather you have to remove the flex plate (auto trans) or fly wheel (manual trans). Then of course there is removing the old seal, making sure it is free of burrs and putting the new one in, and reassembly.

I have a 2002 Pontiac Grand Am only 70,000 km on it. A gift from my Mom. I drive it pretty hard now. I have just been told there is a possible leak in the rear main seal, but to leave for now and wai


Yes...check your oil level @ EVERY FUEL UP. If you're using/leaking more than 1 Qt every 1K miles, then it'll need changed eventually. Which means pulling the engine and an $$ repair bill.

I've a 99 protege replaced the rear main seal in, and leaks again , I was told that the crank was worn and that's what caused it to leak again could this be true or am I getting scamed


unlikley as its only the rubber that touches the crank shaft on any car but it could be warped moving the seal and letting oil out more likeley if its still leaking did the garage do it it may be that the seal was rubbish they put in and are trying to get more money out of you for the sake of another seal was it genuin parts of aftermarket parts as some times that makes a masive difference hope this helps

Possible oil Leak at Knock Sensor


if I'm not mistaken, the knock sensor is mounted on the transmission bell close to the motor and detects the flywheel position. It is possible that the valve cover gaskets might be leaking from the bottom side and dripping onto the knock sensor, but it is also possible that the leak might be from the rear main seal of the motor. If that is the case, you will have to drop the ****** to replace the seal. If the knock sensor was bad your vehicle would not start at all, just crank. Try to wipe all the old oil with rags and look very closely where it gets oily again

Engine oil leeks between gearbox & engine


Sounds like a rear main seal, the crankshaft's rear main engine seal. On newer vehicles, it is a one-piece design, and easy to install. The problem is the engine and transaxle have to be separated to get to it. You would either have to pull the engine and transaxle out of the car together for separation, or drop the transaxle and replace the seal with the engine still in the car.
Of course you'd want to know for sure it was a rear main before you started. Check the oil pan carefully around the rear of engine for leaking there. If you clean the area around the leak, you may spot where the new oil comes out. Parts stores have kits for sale to detect leaks. You put a dye in the oil, and use the flourescent light to spot the oil leaking with the flourescent-sensitive dye in it. I hope you find it, good luck.

I have a huge oil leak in my 98 Toyota Camry It leaks roughly 1 qt of oil for each hour of driving. What would be the cost of repair?


Need to find out where leak is from. Kinda sounds like a crankshaft main seal, front or rear of engine. Front one is pretty easy to change, but rear main seal leak means you have to drop transmission to get to it. But it could be another seal or gasket. Can you tell about where leak is, from oil spills on ground where parked? Look at engine. Is oil seeming to leak from bottom end or upper engine. May need to wipe or clean it off to see where fresh oil leak develops. A mechanic may need to put it on a car lift to pinpoint the leak. Good luck.

How do you get a rear main seal off. A friend siad you can use a scew driver to pop it off this is a toyota celica gt 2002 oh and what do you look for on the seal to determine it is bad will it only be...


Changing a rear main seal is a major repair. The transmission must be separated from the motor to get to it. The way you know a rear main seal is bad is that it will be leaking oil between the back of the engine and the front of the transmission. If it is not leaking oil, then leave it alone. If it is leaking then you have two options. Have some replace it by doing what I have just told you (call around, its probably pretty expensive). Or you can do what I would do, Just check your oil ALL the time and add oil when you need to. Put some cardboard under your car where the oil drips and leave it alone until you want to spend the money.

My Chevy 2002 Tahoe is leaking oil. They told me


this truck is equipped with an aluminum oil pan you could have 1 or several things going on... a stripped drain plug which is causing it to leak or it may be a leaking front seal or a rear main seal. If it is a front seal it is not to labor intensive. But if it is a rear main seal leaking it will require the transmission to be removed since the seal is a 1 piece rear main
