My new 97 jeep wrangler

[jeephound]

I just purchased a 1997 jeep wrangler sport 2 weeks ago and I love it. Of course I did my reasearch on the common problems and expected to have a few when I bought one and I was not disappointed! I already have replaced the exhaust manifold with an Omix (Is this a good one? Has any one had any experience with this one?) and of course new seal on the manifold and the intake. Let me clarify something here...I wanted to get out and play asap so I let the dealer do the labor for me! And of course I have a rear main seal leak and a rear crank leak. Are these really a six hour job? Is it worth trying to tackle myself or should I just take it back in in about a month or 2 and let the professionals handle it again. Any input is appreciated! No I am not disappointed at all... I only paid 5400 for it and expected to have some repairs. After all it is a Jeep!
