Engine oil leak

That would be the $50,000 dollar question. It all depends on what life it had before the swap and what the car it came from had for damage. If it was me and this car was really something I wanted I would likely go through it and change out any gaskets as needed, drop the oil pan and clean it out and do the timing belt, water pump and oil pump. Change out all fluids and start with a clean slate on maintenance, but that is also because I have the tools and materials to do that with no labor costs. For you I would likely inspect the belt and see if it may have been changed it prior to the swap. Then just do the fluids and whatever else needs to be done.

I have an oil leak on our 2003 accord in the bottom of the engine.I identified the leak to be near the transmission under a small metal cover. Any ideas?

Hi ugotwelderdave,

The description points to a bad flywheel oil seal if it is between the trans and engine. Rectification would require removal of the transmission.

My 2003 Honda Accord EX 4cylinder has 69,000 miles and has had no problems since I bought it four years ago with 23,000 miles. Just recently the engine has been leaving small drops of oil on my garage floor near the passenger-side front wheel. And there is a burnt-oil smell from the engine when I turn it off at night. Is it a defective seal and/or gasket? If so, is the repair expensive?

The burned oil smel you experience is probably coming off the exhaust. To estimate cost of repairs we would need to know which seal or gasket is leaking. If you can have someone look at the leak and determine where it is, we can go from there. Please advise.

My Honda V6 had a D Type service and on return I noticed a oil leak. The car was taken back to the dealer and they resealed the sump gasket. On return again the same leak. They now tell me that the main seal is faulty and has to be replaced. What would cause the main seal to give just after a major service?I did notice that the oil level was above the maximum mark. Has anyone else experienced this problem?This vehicle is just out of warranty and the major service was done when it was under warranty. It has 100000 kilometers on it. Any advice would be appreaciated.

The oil level was about one third of the distance between the max and minimum mark again. The work was done at the dealers so I dont know the Quantity. Since my last message the Honda dealer found the source of the leak to be the rear main seal which they replaced and now all seems well. They where able to have a warranty claim for the repair and I wasent charged a cent though the milage is 200 kilometers over the warranty period. Please let me know if there is any thing I should watch out for as this was a major repair and after my experience I feel a bit warry. Thanks.

I've narrowed out it being a pin hole in the pipe, and the bolts are tight. It appears to be leaking around the bolt as pictured attaching the oil pipe to the radiator on the bottom. I just don't understand what could be causing this.

That picture isn't very clear but if you have coolant leaking from that big nut, you likely need a new radiator. If you have trans fluid leaking, there may be an issue with that hose or clamp.

If there's no actual oil leakage then its being burned in the combustion chamber could be valves/rings/guides/seals.

Oil leaks and I guess crankshaft oil seal needs to be replaced. I am hitting 105k miles on my accord and I need to change the timing belt too as per Honda's recommendations. Can this be done as a single job, meaning is it the same effort to get this done together so tht it could save some money for me on labor?

If you are talking about the seal located on the same end of the block the answer should be yes. You are at the time for a water pump, timing belt tensioner and the seal would be a simple thing to do while they are in working on the other items.

I have a 2000 honda accord with 124K. I loose approximately 1 quart per week with high speed highway usage. I don't have an oil leak in the oil pan. The car does not burn oil because it passes all inspection tests. I believe the oil loss is from the valve cover because it is soaked with black oil around the right side between the belts and the engine. It also has a lot of oil in the back of the motor just above the transmission. How can I determine if that is the problem and how do I fix it.

Hi there,

have the engine cleaned down and re check for fresh leaks around the rocked cover in a few days time, if leaking advise here for instructions on replacing gasket.

I have a major oil leak on the lt front up by the wheel. I can see oil on the ground. Put in 2qt and it ran right out on the ground. Can was parked and saw a huge puddle on the ground. It ran out in like under 2 hrs. Pulled dipstick was dry. Checked all I know to find it and still no luck. This is the 4 cyc. And has 270k on it. Could a busted seal cause that big a leak? Or maybe the oil pump? Did not see any leaks on the pan or drain hole.

Brian if the car was not running, check the oil pan for a hole! This is the only place that will cause a leak like you descibe!

Did you check the oil filter and the connection of the filter adapter to the engine?
