    V6 Off Topic Lounge
    I'm looking for a good first car and I came across a red 2003 mustang coupe. It has 151k miles on it, a cracked windshield, and an oil leak. Other than that no major issues.

  6. 2002 Mustang V6 Valve Cover Gasket Write Up

    V6 Tech
    The reason I replaced my valve cover gaskets was because my oil was leaking into my spark plug well and it caused my car to have a really hard idle and misfire. After switching the gaskets, sparkplugs, and wires the leak stopped and my car has been driving better than ever. I'm not responsible...

    5.0L Talk
    I've recently purchased an 87 5.0 GT and while driving it around I noticed the stock oil pressure gauge fluctuates from the bare minimum line of normal to about the 2nd and 3rd lines.

    My mechanic is going overseas for a while and my 05 4.6L has an oil leak. Looks to be around the oil filter area, I can see oil accumulation on the oil filter and it's primarily on the left side. Can someone point me to a thread that will point to a fix? Thanks for all replies and help.

    Changed my plugs today on my 99 cobra. 134,xxx miles. 5 of 8 had oil on the hex and the threads (probably from unscrewing it). It was a good amount too, enough to drip. The three cylinders closest to the firewall on the passenger side however did not have any oil on them. Any ideas? could it...
  12. Need help identifying oil cooler adapter mystery port

    SVT Cobra Tech
    My 1999 Cobra has started leaking oil and a preliminary trace has led me to the area of the oil cooler adapter. If I were to hazard a guess, it looks like the oil pressure sending unit might be the culprit; however, it's also possible it's coming from the "port" located directly below the...
