I've noticed a few mentions of stock head pipes being titanium, I thought for sure they would be steel or something cheap. I have a 2000 426F, is my stock header titanium? One other question, I noticed after doing my valve adjustment that my water pump weep hole has a slight bit of coolant in it. If I touch a clean white towel to the weep hole it will get a bit of blue coolant on it but it's not dripping on the skid plate or anything, does that mean that my water pump seals are shot? I also noticed that my radiators are completely full, so it doesn't appear that it is losing coolant.
