Engine ticking under acceleration, S60 2002

With that mileage a contributing factor may also be that the manifold/head mating surfaces may not be perfectly flat any more. As can also be the case when removing the head from the block, once you take it apart you may have trouble getting the gasket to seal back up properly without machining the surfaces.

Hijacking a bit here.

I just diagnosed my 2004 2.5T with a leaking exhaust manifold gasket. There's an obvious sound, I can feel warm air on my hand just above the gasket for the cylinder furthest from the cam gears and there's soot on the block just above the manifold.

Is it likely to be just the gasket or should I assume something else has broken causing the gasket to break and if so what.

An update on my issue. One of the bolts were missing and after replacing it everything seems to be fine. Let's see if it'll still be so after the 1000 km weekend drive I'm about to do.
