May I ask you what year your Contour is? And how many miles do you have on it? Because '95 Contours have the chain tensioners that bleed off oil when they sit overnight. Did yours fail on first cold start of the day? Another forum member with a '95 had his chain cover off to update his chain tensioners to the newer style (as per Ford TSB) at around maybe 115,000 mi and he said all his chain guides were worn out as well.
