Question about 1999 Mercury Cougar

1999 Cougar V6 2.5L High Pressure Oil Line Leak?

I have an oil leak on the top left side of the engine. I'm pretty sure it's a high pressure line. It's leaking right where it connects into a golden nut. That's about 1 inch wide by 2 inches long. Is this a high-pressure oil line? Oil is leaking out of it. Does the whole line need to be replaced? Diagrams would be best with your answer please!! I just bought this car for 500 bucks, I have no choice to get it running. I've been doing everything myself. So telling me to take it to a shop, isn't really helpful. THANKS!

    At would be the high pressure power steering hose. The part should be available at any good parts store like NAPA.

I believe it will be the line to feed your oil pressure indicator in your dash, you can cut the line ( if you have enough length in it) and remove the olive, which is a small brass fitting that goes over the pipe, if you can't remove it then take the small piece of pipe with the olive on it and buy a new olive and refit it to your engine and you Gould be good to go

    What? Maybe in 1945! Pipes and olives? What a you talking about?

  • Craig Wilson Jul 14, 2013

    You have to be more specific when asking a question, you didn't mention what the pipe fed or what it was for, anyway good luck, with your attitude to someone helping you mite need to refrase your questions, you should be still able quite easy to repair it, the picture would have been handy straight up

if that is the case the fitting is probably cracked and unless you replace that fitting it will continue to leak.

We performed exactly the same repair on December 28, 2010 withexactly the same outcome. Finding no other references to this oil pressureproblem anywhere on the internet and the fact that they both happened the samemonth, I can only wonder if there are some incorrectly made gaskets hitting theshelves.

SOURCE: I have a 2000 cougar and its leaking oil when its

the best way to locate the oil leak, if you can't see where it is coming from is to park the car overnight , and put a large piece of cardboard under the engine, so where the oil leak is, it will drop onto the cardboard, then the next day, look under the car, and see where the oil is on the cardborad, the leak should be in the area of where it is on the cardboard. also, the leaks could be anything from the oil pan gasket, oil sending unit, valve covers, intake manifold gasket. or the rear main seal. hope that this information was very helpful to you.

Oil change but oil continues to blink


Simple check first. Check your oil and make sure it is reading correctly on the dipstick. If it is low then add oil and watch everyday to see if the oil drops. If it is dropping quick enough to notice in a day or two then you have a leak somewhere an need to find that. A pressure test may need to be done as well to make sure oil pressure is high enough.

You have an oil leak, have the engine pressure washed top and bottom and drive it, then inspect the engine top and bottom for an oil leak.

1999 mercury cougar power steering leak


it depends if it is your high pressure or low pressure line if it is the high pressure line you can purchase at an auto parts store for about $60-$70. If it is your low pressure line good luck finding a replacement. But what I did that cost me about $5 was buy a gas line that fit and a couple clamps and I cut out the section with the leak and installed the gas lin in its place. But remember you can only do that simple fix with the low pressure line.

I have a 2002 Ford F-250 Diesel 7.3 litre Super Duty truck. It is leaking oil from an area beneath the fuel filter. What part would I need to repair this leak?


there are 2 high pressure lines that attach to the high pressure pump near the front of the engine left side. the o rings leak. I would get them from the dealer, or a shop that does a lot of Diesel work. Its not a easy job.

Gauges say no pressure in engine 1995 vw golf


Get someone to check oil pressure with a mechanical gauge, to verify whether you have oil pressure or not. These engine/vehicles, have 2 warning sensors & a control module in the instrument panel. Once you know you have pressure for sure, then you can proceed from there.
