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........
i also have this problem and when i talked to my mechanic about it he said to try and replace 1 qt of oil with a bottle of lucas oil. it did wonders. i would say took over 50% of the ticking away. he said over time there is dirt that builds up on the rockers and rods and the lucas oil cleans it out. it took about 5 min of the engine running to make the difference.
