I was wondering if anyone else has this problem? I run 91 min fuel have ran cleaner, and still loud ticking. Lifter at 66k ??? it's too soon for that surely.
I drive this car hard lots of WOTS so that's not it. We have replaced Timing gear all three gears and chains. A new Torque converter as well all at fairly
low k and all covered with our warranty plus 100 deduct. I am hoping this
car will stay together, love driving it but man that's a ton of stuff don't you
think??? Should I stay or should I go now???
Thank you all in advance. MJ

Re: 2004 srx v6 awd Ticking engine
Are you the first owner? Mileage when the work was done? How long (miles and months) after the replacement of the timing gears and chains did this start up?
My first stop AFTER you get some feedback here and have some clues would your private mechanic, if you have a knowledgeable and experienced one you trust. I would pay for that opinion. Then off to the folks who did the engine work to see what they say.
If you are still under warranty and can get this ironed out, this may not be a game breaker.
My experience is that "Ticking" is most often caused by lifters...
On your particular year SRX... Most often, the Roller Finger Followers fail. Google "PIP3381" for more information on that. The cause is faulty materials, or faulty installation, so mileage is irrelevant.
Also, even though our SRX's are Overhead Cams... however, there are hydraulic adjusters riding under the followers, and when they go bad, or get clogged, they will allow for some slack to be created and then "Tick" when being hammered by the Cam because of the slack space.
Also - - you can have a bad Cam - - Cracks can develop if faulty metal was used, creating ticks as the cracked cam passes over the roller fingers. Same thing for the Rollers.
Any of these parts can fail because of poor oil flow, or an excessive temperature event.
You can pin the offending valve down by taking a long rod, placing one end to your ear, and the other end against various locations of the valve covers - - the noise will be louder as you get closer to the source.
