Help with ticking from my 90 4runner
i have been trying to figure out what is ticking from my 90 4Runner. I thought it was the lifters so I tore the thing apart and reshimmed all the valves, None of them were to far out of spec, after I put it back together it still ticks. The ticking noise if much louder when accelerating. Now I am thinking it might be an exhaust leak. I removed the exhaust manifolds and used some high temp sealant on the gaskets but that didn't help. I can hear the ticking coming from the engine compartment, and also from the exhaust pipe itself. If I get under the truck it sounds like there is a ticking coming from the cat. I have felt around as much as possible with my hand but can't feel any leaks. I would really appreciate any help you guys can offer, I'm stummped.
Thanks

worst case is a spun bearing allowing enough free play in the connecting rod allowing the piston to make contact with the cylinder head... yeah i had to deal with that. pull the oil pan and check your crank. its possible to fix with a crank kit if your heads arent too damaged as mine were. good luck, hopefully this isnt the problem, i ended up putting a whole new motor in my 4runner.
