How to Fix a Motorcycle Engine Oil Leak

It is not necessary for you to be an expert in motorcycle maintenance to know how to fix a leak of motorcycle engine oil. Knowing how to locate and rectify the problem will not only help to prevent larger engine problems due to an insufficient level of lubrication, but also accidents from others skidding on oil deposits.

Step 1 - Prepare

There is some preparation work required before you will be able locate and fix a motorcycle engine oil leak. You should make sure that the engine is cold when the work is undertaken to avoid injury from burns. Position the motorcycle so that the engine is over a drop cloth or newspapers laid out on the floor. Check the manual for the motorcycle to determine whether a particular method of repair is recommended.

Step 2 - Inspection

You will need to undertake a thorough inspection of the vehicle to locate the precise source of the leak. For some motorcycles, this will be easier to achieve with the help of a jack stand. Finding the point from which the motorcycle engine oil is leaking will help you to determine what method to use to repair it as well as the severity of the problem. Be aware that there may be leaks from several locations at the same time. If this method proves unsuccessful in finding the leak, it can be found with the use of an ultraviolet dye, flashlight, and the corresponding glasses. Pouring the liquid into the tank will enable it to flow through the leaks and you will be able to shine the UV flashlight to highlight their location.

Step 3 - Repair

There are several methods that can be used to rectify the engine when it is leaking motorcycle engine oil, with some being more effective than others. There are products on the market which work by stopping the leak from the inside by coating the tank. There are occasions when the substance thicken too much and cause a clog. Alternatively, you can use a sealant that can be sprayed onto the outer surface of the tank to create a seal that will stop any leakage.

Step 4 - Replace

There may be some motorcycle engine oil leaks that are so severe that it requires the replacement of defective parts. This should be relatively easy to undertake when it comes to hoses and connectors. Prior to replacing any connectors that appear to be the cause of the leak, try tightening them in case they are actually leaking because they have come loose. After tightening them, wait a few moments to check whether it continues to leak. If the fasteners or hoses are defective, replace them rather than attempting a repair. Where the problem of leaking oil persists, it may be necessary to remove the engine in order to repair it properly. This is best undertaken by a qualified mechanic.

camry 1993 oil pump

No reason to toss the engine then. The oil pump drive sprocket is located behind the timing cover and he would have had to remove a lot of things to have definitively told you it was the pump leaking. Even then, you shouldn't have to replace it. It's far more likely to be a crank or cam seal that's leaking. Just the fact that he told you 1200 bucks would make me run, it's a 6.5 hour job to change the pump. I would suggest taking it somewhere else. Without knowing the service history, this is what I would do if it were my car: Since you have to remove the timing cover to get at the oil leak, I would take to a Toyota dealer and have them attack it as a timing belt job, tell them; "while you're in there, fix the oil leaks and replace the water pump". The labor for all of this is about 4.5 hours (~$450.) + parts (timing belt, water pump, seals (~$250). This gets you a whole bunch of maintenance for about 800 bucks. Now if you have had the waterpump and timing belt done already, you would be looking at 4 hrs labor and a handful of seals (~$30) to just fix the oil leaks.
Just out of curiosity, what part of the world are you in? My dollars relate to the Vancouver, Canada market.
