Silver ghost, how many miles are on your TB? One suggestion that I have is to as a can of Seafoam to the crankcase. This will clean most all issues with gummed up lifters. Goggle it & read up on it. You can get it at WM. I use this on all my cars just to keep the engines clean; valves, rings, etc. Keep us posted

If it goes away after a few minutes or seconds it could be the fan unit. Mine has been doing it for 2-3 years now. I know I will need to replace the fan unit someday.

I will try the seafoam in the oil, and get back to you. My TB has 117,000s on it

follow up

I used the seafoam in my oil and the fuel. This stuff is awesome and will keep on using it before every oil change. Solved the problem.

Ticking Sound

So I too have a ticking sound but it only seems to happen when slowing down and after it downshifts when coming to a stop the ticking stops. I can't seem to find the problem since it only ticks when moving and I cannot reproduce the issue when parked. I can only hear it at low rpm. I have a co-worker with the same 5.3 motor only his is a 2006 and his does the same thing.

So, I am a little late to respond...

I have a 2006 5.3L Saab 9-7X, and the ticking sound proceeded the loss of a DOD lifter for me. Very annoying. Have replaced 3 of the 4 cylinder's lifters that use the DOD.

That said, do you get intermittent check engine lights or does it have a bit of a rough idle on occasion? Mine is doing that currently, and I am pretty sure it's the last set of lifters wanting to die but not actually doing it....

Same Ticking Sound

I've also experienced the ticking sound. Performance doesn't appear to be lacking, but the motor ticks at low rpm and after it downshifts. It stops ticking when it downshifts to 1st (1st having a higher rpm directly after shifting from 2nd) and the ticking stops completely when stopped or when accelerating. I'm preparing to clean the throttle body, but beyond doing that I have no other course of action to explore to help resolve the issue.

05 TB, 5.3L, 115K, 4WD.

No other issues to complain of, except for crappy fuel economy, but I've done what I can to increase/mitigate the poor fuel economy.

If anyone has ideas, answers, or theories, I'd love to hear them.

Thanks

I haven't experienced the check engine light or rough idling relative to the ticking sound I'm experiencing. The ticking has occurred for some time, but never appeared to be a serious issue other than an annoying sound. Never had an issue with any of the lifters and I've owned the TB since it was a newborn.

I've always stayed on top of the maintenance and have taken good care of my TB. Maybe I'm being nit-picky and this comes with age of engine components.

@ Cycloplathic......The ticking MAY be coming from a sticky lifter. What I have suggested several posts back, is to try adding a can of Seafoam (goggle it) about 200 miles before your next oil change. It will clean some of the old sludge out of the lifters, rings, etc....
