Greetings everyone. New to the forum. My 2000 Tundra has exhaust leak-sound when cold that comes from the engine compartment. I first thought it was the exhaust manifold but after further investigation it is not. It seems to be coming from the back of the engine compartment, possibly underneath the intake manifold. I'm curious to hear if this is something common or if anyone has any advice. Thanks in advance!

I don't know but I'll give you a bump back to the top to get some more views.

Check for a leak where the Y-pipe connects to the manifold.

All I know is the exhaust manifolds on many of the first ones were notorious for cracking, check them good.

Does the sound seem like it might be a slight knock inside the block? The 03 and older (i think) engines are notorious for piston slap on cold mornings. Mine has done it since it was new, and now at 90k, i have had no problems as a result. Just a thought...
