Hmm, the land rover is 4.0 V8 I think and maybe yeah cracked manifold but havent chance to go underbody and check the exhaust system.
btw I didnt smell any exhaust fumes while stand near engine bay tho.
Doh! I forget about that. :doh: thanks to let me know also I don't know if cat plugged up, I didnt have time to look underbody on exhaust system
