Just bought a '97. Runs great except for an intermittent oil leak. Only seems to leak when engine cold, once warmed up there is little to no leakage. Leak is on passenger side but I cannot pinpoint exactly where it is coming from. A bit maddening given the intermittent nature. Thoughts, suggestions?

 

could be valve covers... rear main... you kinda have to have a general idea.. honestly tho on a 97 i'd let it roll unless you want to start doing some mechanic work
