My 4x4 has been sat in my gargae for about 5 days whilst I strip out interior to look at interior body condition, replace clutch cable etc. I haven't started it in that time, partly because battery is knackered. I have only jacked up nearside front to remove wheel and look at condition of front wheel arch, putting wheel back on after and returning car to level. Now, there has appeared an oil patch, about a coffee cupful, just under the near side front cv joint ish. Any idea why, all of a sudden this has appeared, and what might have caused it? cheers John
