Nickel and diming

If it makes you feel any better my engine has maybe 500 miles on it since the rebuild and it's been nothing but problems. I was fighting a random missfire for 2 months, turned out to be the either the PCV valve or fuel filter. Both were new but I replaced them on a whim since I had 2 new ones on the shelf. Replaced them both at the same time and problem disappeared after.

Car was running great for less than 2 weeks and now an exhaust leak on the passenger side manifold at the head. I don't have room to work on it right now so back to the mechanic on Monday...
