Well I did all of those things and still ended up with a new valve job which failed and then had a heart transplant by the graces of my donor and Mayo Phoenix 15 months ago. Sticking with the analogy of care care, I now have a new engine which works great. Still I have the old exhaust system and catalytic converter which are not up to par, my upholstery is worn out, My struts and shock absorbers are shot, The frame is bent. All of that considered I am alive to complain about the little things.
Best always,
s!
