noticed a "ticking" noise

[jsp70]

Last night, a noticeable ticking noise was detected coming from under the hood. It wasn't the typical sound you hear from the fan running, but more like a lifter/tappet or a small exhaust leak. The dealership said the noise was a common problem on the turbo motors and I was wondering if this was true. Has anyone who owns an '03 GT Turbo experienced this?

Thanks for any responses that may help...

Welcome to the forum, jsp70.

I experienced this problem with my 2003 Inferno Red GT. [:0] Read about the SAGA of the "mysterious" turbo engine noise here: http://www.ptcruiserlinks.com/forum/...?TOPIC_ID=3426

No ticking noise here @ 13,000 miles. That sounds like the dealership's "I'm to freakin' stupid and don't care about you go screw yourself unless you can bring your car in here for something I can charge you full retail for" standard answer. Hope there are other dealers in your area. Although they all seem to be trained with this response.

mine does it. Has since new. I notice no ill effects from it so far. And I did say, So far[8D]

I've had that sound since new also, some are of the opinion that it comes from poorly adjusted lash adjusters.

So far I can't see any problems from it, to be honest i am afraid to let them wrench on the motor at the dealer.

It is a distressing problem for sure, on one hand I'm not sure if letting it go will cause problems down the road, on the other hand I feel more trouble will come of the repair.

I don't really have the time to fight back and forth with a dealer on this kind of thing, I need this car every day.

My 03 Turbo did this too. Dealer replaced the cam bearing caps. That fixed it.

wsd0836,

Did they replace the bearing caps or "hand file" them as described in your post?

[wsd0836]

Well...I was told that they were replaced. But who really knows. It was a warranty repair so the details of how it was fixed were not on the paperwork I received.
