I have a ticking sound for awhile, I thiught it was a bad exhaust manifold gasket,,,but nooo, anyone ever try to take off the exhaust manifold on one of these 4.7's ?????? it's a job and a half just to get the heat shield off, the top two bolts come out, the two bottom ones broke off, then try to get the manifold bolts off, if you can reach them,,,,, oh sorry for rambling on, this job is a pain int the azz,,,,,,, I hace a cracked exhaust manifold, it looks to be cracked all the way around between the first and second cylinders on the left side of the engine,,,,,,,,,,,,fun fun fun but I think that toyota gets $1200.00 to replace the manifold, I will be welding it, if I can get it off........
