I just recently bought this jeep, and I have started cleaning, degreasing and replacing things. I replaced the valve cover gasket and the pcv tube and now there is blue smoke coming from the exhaust and from under the hood somewhere. I did double check the valve cover bolts and tightened a couple of bolts and still the same. Before replacing the pcv tube I did notice some smoke coming out of this tube. Should I sell it or fix it.

Hi there,

Blue smoke is oil burning, i would determine if its rings or valve stem seals first, a leak down test will help here, valve stem seals will be a lot cheaper to fix than a ring problem.
