I bought a 2000 Tundra Limited a few months ago. The people I bought it from replaced the drivers side w/ a new manifold. After getting the vehicle it was obvious there was still an exhaust leak.... to make a long story short... I had the passenger manifold fix (welded) and the new drivers side taken apart, inspected and reinstalled. The manifold was not bolted tight and two bolts missing from the heat shield.
I still hear a tick tick sound especially on the highway. Is this a piston slap sound or should I continue to look for more manifold leaks? I expected to hear a nice smooth V8 sound from my Toyota. I could turn the radio up but that sounds like a tin can. Everytime I have work done to it the sounds is reduced but it is still there.
Any suggestions other than headers?
