Well, 200,000, it's about damn time. Noticed a lot of oil on the block today when I was disabling that damn air pump (mmm, no more clickity clack on startup). Planning on completely cleaning of the engine, and then checking it every few days so I can pinpoint the spot of the leak to verify that it is the head gasket because I go through with this. Maybe I'll be lucky and find out that I spilled some oil down there at the last change. While I'm in there, I think I'll change the manifold gasket. I can smell exhaust in the engine compartment when it's running, but a light breeze could've brought it from the tailpipe into my nose. Hm. Comments?
