tick-tick-tick
my 92 22re makes a ticking noise strikingly similar to the noise it made when the timing chain was making before it was replaced. the noise is most prevalent at cold starts, on hills, and when i'm heavy on the accelerator. i removed the valve cover and the guides are perfectly in tact. before i changed the timing chain, i could rev up to 2250 in neutral and hear the ticking noise constantly whereas now, the noise cannot be heard in neutral at all. ideas?

I'm new to Toyotas so I don't know if this applies, but with other vehicles I'm more familiar with that sound could be caused by your lifters. My friend's older truck does the same thing when climbing hills or putting strain on the engine.

the reason i think that's an exhaust leak is that it only occurs when the engine is cold(manifold/head aren't expanded and compressing the gasket fully, which helps seal the leak), and under load(more exhaust pressure seeping out). mine's got a nasty exhaust leak from having one of the manifold studs being cracked off, as well as both air injection tube bolts broken off inside the manifold. it's a mess.
