If there is no sign of coolant in the sump, then it's possible that you don't have a BHG...
Well my valve cover gaskets are brand new and so are the bolts on the VC's. People say you should notice discoloration on the dipstick and on the oil cap, and I haven't noticed either, so maybe it's just those coolant plugs. No idea where the oil would have come from though... maybe from before I replaced the VC gaskets. How do I go about replacing the plugs? If you don't feel like explaining, is it in the TSRM?
