Well, my1998 F150 XLT 4.6 4x4 finally broke my heart. It had the the exhaust leak sound around mid December and has continued to get louder. The weather is beautiful today so I decided to investigate. Turns out the manifold is completely cracked. It has 153,000 miles on it and this is the only major problem I have ever had with it, so I will attempt to fix it on my next weekend off. I have done just about everything with vehicles at one time or another but this will be my first manifold. Should I change the passengers side also? I am open to all suggestions other than to get rid of it. I love that truck! Thanks in advance.

Are you replacing it with another stock manifold? If so where did you get it? I have the same issue and just might go with a set of JBA shorty headers. If I can get a stock DS manifold for a good price I'll just do that.
