So I recently bought a 1998 Honda Accord a few months ago. It only has about 130,000 miles and I have recently found an oil leak. I pulled it up on some ramps and once I got under it I found what appears to be some sort of vacuum hose that was loose and I assumed that the leak was originating from there. I put the hose back and the car is still leaking. It doesn't do it while its idling I don't think. The hose has not come undone again either. I can't really tell where the oil is coming from. I attached an image of the hose that was loose.

My oil pressure sending unit was leaking; replaced and those drips declined a lot.
It's located immediately above the oil filter on my '97 4 cyl engine.

Don't know if this is helpful to your V-6.

 

Thank you for your quick response. Unfortunately the leak is not coming from the side of the engine where my oil filter is located. The leak is coming from a little higher on the engine towards the firewall on the driver side. It appears to be coming from somewhere directly below the distributor cap. I am attaching a new image from around the area. I removed a bolt that is hollow and has a few holes in it from right around where the leak is originating. There was what I believe what was left of a gasket or O-ring from around the area as well. Also an important note. I now believe it is transmission fluid or coolant that is leaking. I think the previous loose cable was unrelated.

Does anyone know what this bolt is? Sorry... I forgot to ask

 

Okay so the bolt appears to be a "line bolt" for my transmission. The bolt connects to a radiator hose for cooling purposes. I don't know what caused the leak as of yet, however the washers are a special type that are made by Honda that when tightened, crush down and spread out to make a seal. Anyone have any other ideas. Does that sound correct?
