I don't know the specifics, but my car started to tick at 50k and went 65k more miles with no problems. The piston ring was the cause of my 4v failure. It's annoying, but if everything is good I wouldn't worry about it.

well i found this regarding TSB tick noise
TSB 03-11-04 Engine - Mustang Cobra - Tick Noise From Engine - Cobra Vehicles Equippe - ModularFords.com kind of bummed out b/c mine appears to show this "tick" symptom drivers head. I am needing some feedback from LSS regarding this head tick noise. What's the fix? A neighbor suggested i do a compression test before i continue putting miles on her but said this valve guide tick shouldn't be catastrophic.... IDK what you think? huge thanks Last edited by seco; 10-11-2008 at 10:07 PM. |

If ya get a chance, find this book: "Iron Fist, Lead Foot", you can learn alot about the car. It's about the creation and story of the 03/04 Cobra. And BTW, no where in the book is the cobra referred to as termie

Found this. It only mentions the Cobra but I'm sure this applies to all C head Mustangs. I'm sure this was similar to my 4V tick. LH as well.
ENGINE - MUSTANG COBRA - TICK NOISE FROM ENGINE - COBRA VEHICLES EQUIPPED WITH ENGINES BUILT BEFORE 11/1/2002 ONLY FORD: 2003 MUSTANG ISSUE: Some 2003 Mustang Cobra vehicles with engines built before 11/1/2002 may exhibit an unusual engine tick noise that is present at all temperatures during idle. This noise may be due to valve guide wear in the left bank cylinder head. Guide wear manifests itself as a tick noise which can be heard at the rear of LH head, through LH catalyst, at the LH front wheel well and may not be heard with the hood open. ACTION: Use the diagnostic procedures listed in this article to evaluate the vehicle condition and replace the cylinder head if applicable. Refer to the following Service Procedure for details. SERVICE PROCEDURE NOTE: THIS REPLACEMENT CYLINDER HEAD WILL NOT IMPROVE OR REDUCE PERFORMANCE. In order to diagnose noise, the following items must be checked. Verify noise by placing a stethoscope on the back of the left head near the exhaust ports. Verify that the noise is heard in the left side exhaust system (left side wheel well or catalytic converter, from underneath the vehicle). Try to isolate the noise by canceling the cylinders, by unplugging the injectors one at a time (start with #8 cylinder). Verify that there are no exhaust manifold leaks. Check to make sure that the camshaft spacers are in place. If not, install cam spacers and retest vehicle. Check for proper cam sprocket bolt torque, retorque to spec Check for spongy lash adjusters Verify that the timing chain tensioner pin has been removed. If the above diagnostics does not eliminate the noise while the cylinders are cancelled, and the engine was built prior to 11/1/2002, replace the left side cylinder head and cam assembly with Part Number 3R2Z-6049-GA.

WHERE'S MY CHECK AT FOOL?????!!!!!!!!
|
My 04 has 45k on it and I have no tick
Quick ck is park it running with the D/S close to a wall. If it ticks you will hear it. Also dont confuse the injector ticking noise for the other "tick"

The tick that Ford refers to in the TSB's posted here is very obvious and sounds like you have serious engine damage.
In an open area with the car running and the hood closed, kneel next to the driver's side wheel well. If it sounds like metal on metal and the motor is going to fall out of the car, you could have the tick. Otherwise, it's injector noise, exhaust leak or normal engine noise. If you have longtubes, I almost guarantee it an exhaust leak. 99.99% of these cars with LT's have/develop a small exhaust leak. Speaking of spark plugs. Check them. A plug that's working it's way loose will rattle and tick and cost you a motor. Also, check/change the blower oil if you haven't recently. The Heaton's are very rattly when the oil gets low or old. Have you done any high speed pulls in the car recently? Have you done a leak down test? No. Very few Terminators actually have a tick due to valve guide wear. My car was built in May 02 and never had a tick. Of all the 03/04's I've heard personally in the last 6 years (several hundreds), only ONE had the head tick and it was very, very obvious. Quote:

The revised heads weren't released until after production ceased and have more spark plug threads. Quote:
Driving next to a wall in 03/04 Cobra will just make everyone paranoid about having the tick! There's a reason these cars don't have knock sensors...it's because the motors are so damn noisy!

thanks 2k4mk1 and RaceRat and all....
i have a garage and I park on left side so the tick is indeed obvious with hood closed. I confirmed the tick is not the injectors, but the tick isn't loud like the "motor gonna fall out of car" as RaceRat put it. I know what exhaust leaks sound like.... and it doesn't seem be that. I'll see about the spark plugs, compression check, leakdown test... What's done during a "leakdown test"? I've heard of some type of T fitting kit one can buy to better distribute coolant flow to drivers head. How true is this? What's all involved with installing this T fitting? What does TSB stand for? I drive a 2003 Mach 1. Sorry for all the questions ![]() .... LSS has always been an excellentsource of tech advice for me |

my tick was minimal. didn't sound like a major issues. We have had a couple 4v cars on the lot over the years with the tick. I've heard of the 4v tick ALOT, but no one ever describes their noise as massive. Maybe this is why the TSB only covered some cars. They knew that the ones with minimal tick were not a major issue.
