I have a 99 jeep tj 2.5L and a cracked exhust manifold.Is this common?and did chrysler use this motor in any other auto thanks jack

 

Very common headache with TJ's.
Not sure why you're asking if DC used the 2.5 in other vehicles though.
Suggest you do a search in the TJ Forums at jeepsunlimited.com or jeepforum.com and you'll get a huge amount of information, including the best solutions/replacement manifolds.
Good luck.

 

I'm not sure if anyone can help me with this but any info would be greatly appreciated. After driving @ high speeds on the highway oil will leak out somewhere and drip onto the starter area. This does not happen every time that the vehicle is driven... only one in a while. just as quickly as it starts leaking it stops. The oil filter housing has been changed and it is not coming from there. If anyone has sen this before or has any ideas let me know.
