Lifter tapping noise !

I know these engines do not have lifters but that is what it sounds like.
I have read a lot of the searches on the dreaded Tick and they don't compare with what mine is doing.
It is quiet at start up and idle but when I take off in first through fifth at around 2 k and climbing under load I hear it.In all gears if I stop climbing and stay at a particular rpm its gone but if I get back on it to go, there it is. Kinda like the old lifter tap when the timing was off. I took it to the muffler shop hoping it was just an exhaust leak and they found none, Any suggestions would be much appreciated.

Does it make the noise if you rev it up in neutral? If so break out a stethoscope (aka long screw driver) and see if you can pin point it. I had main tensioners go bad that would make noise at random times.

No, no noise at neural. It has to be under a load , idling or coasting at constant speed wont make it happen but thanks for the suggestion.

Re: Lifter tapping noise !

Just throwing this out there, is the A/C (defrost) on? I was thinking the tensioner was going bad on mine, but when I shut off the A/C the noise went away. Sounds like my compressor is going bad. Just a thought. Curious what the solution is for you....
