What could this leak be?
My 91 LS has just reached 276,000km with no probs until this morning! I noticed an oil leak (not sure if motor oil, however very thin in viscosity) in the vicinity of the oil filter/front left wheel arch/suspension areas. I inspected the plumbing around the oil pan etc with no evidence of leak. However, I did notice power steering rack slightly "wet" with traces of oil around alloy wheel and near rack dust boot. Any ideas?
