Ticking after PM (1 Viewer)

[rolliges]

Happy Monday,

Did quick search first; still have questions.

PM done this weekend:
3 new OEM belts.
Replaced valve cover gasket; new spark plug seals (both VCG and seals hard and brittle); cleaned throttle body; new TB gasket; new ventilation hoses, new PCV and grommet;
Flushed radiator, checked thermostat opening temp, new coolant.

Ticking noise is heard in drivers foot well. Only while accelerating and under normal load (driving).

Sounds more like a vacuum hose than anything metallic. Pretty sure all hoses reinstalled correctly, and nothing torn or cracked.

What did I miss or do?

p.s. LC has 163K miles

just spit-balling here.. but maybe air in the coolant lines or heater core? Also, there are several vacuum hoses in and around the throttle body as you know - you may have disconnected one at the non-TB end down near the back of the manifold. worth checking, but I would expect it not to run well.

Let us know what you find!

I'm well acquainted with the hoses after yesterday. I'll check them in a few minutes.

LC runs smooth otherwise.

Possible blow from exhaust manifold? Did you put a spanner on them during your PM....you know...just to check? Sometimes if you have a failing exhaust manifold gasket and you start to tighten things up the gasket fails, the resulting 'blow' actually sounds like a ticking, even stranger is you can rarely hear it when under the bonnet but it is quite prominent when under load i.e. driving. Flexible exhaust joint can 'tick' when it gets a few miles on it. Try making the noise lessen by coasting and then accelerating hard to see if the noise is louder the harder you work the engine. Spark leads when not quite on the plug might not produce a misfire but will tick if any spark is jumping to earth, grasping at straws but heh every little helps.

Found the hose! Little one that connect to bottom of EGR modulator (green spaceship). Easy to miss; easy to find.

Need to remove this pesky EGR system!

Thanks all....

As you sounded so confident that you had put back all the pipes I was thinking too deep, glad you have it sorted

regards
