Default 1999 Mustang Cobra with tick/knock in pass. side head

Hello all, I'm new to the group here and I'm hoping to get some experienced advice here. I've got a 1999 Cobra that has slowly developed a tick in the front of the passengers side head. I've scoured the net and found reports ranging from a rod knock to worn valve guides. This seems to be a known issue from 1999-2005 from what I've gathered on several google searches and you tube videos. It is as quiet as a church mouse when the motor is cold but once it comes to temp. it's quite annoying (and embarrassing). It has become progressively louder over the last 3-5 months. I can feel it in the valve cover by touching it. I'm planning to pull the cover off and have a look later this week. Can anyone shed any light on this?

On another note, I can't find a recall sticker under the hood and according to the dealer, my car has never been in for the intake manifold mod to unleash 30 horses out of a design flaw. Without pulling it apart, is there a way to verify this? I've driven other Cobras that seem a bit peppier than mine.

The head tick is more a symptom of the 03-04 cobras...the 99 recall addressed the lack of power and used a revised intake to gain the advertised hp from the 98 (305-315)...
Brutal what's your take? The 99 is your "world"

I have a tick/knock on the drivers side head of my 01 with 44,xxx miles on it. After doing alot of research and some diagnostics I am getting the sick feeling that it is rod knock. My tick comes on as soon as the car hits NOT. From what I've read everyone who has finally gotten down to finding the problem with this engine have had bad rod bearings. I've got about 3,000 miles left on my warranty. Fingers crossed.

call 1-800-FORD-SVT, though they're FPG now and you can ask them about the fix. Should be able to give them your vin and they can tell you if it was or not. The fix was intake, exhaust and revised tune.

Yeah that was the "recall" a "tick" in the drivetrain is not a "recall" item...it's a worn valveguide Brutal where you at man?

Your correct some 99 heads experienced issues, it was more common with the exhaust valves, no recalls were done like the 03's though, I'd like to actually hear it..
It could be something minor like running the wrong oil viscosity, if you currently use 5W20 I'd switch to 6.75 quarts of 5W30 and add an 8oz bottle of Militec-1
And like 2oo5GT said if you call SVT with your Vin# they'll tell you if your car has been in for the Fix. Also Ford put a paint mark in the middle top of the alternator and on the drivers side front bottom of the lower intake, if your computer was reflashed they'll be a sticker placed on the drivers side of the hood underneath near the headlight!
