    I have an 07 GT 5 spd manual and it just hit 85k. Completely stock besides coilovers. I want to make sure it doesn't blow up so I'm going to do some maintenance. I have royal purple 5-30w for my oil change, i plan on getting spark plugs but not sure what brand. I already put an air filter in it. Should I do coils too? I've also heard of guys cleaning the throttle body. Should i do that too? Should I seafoam it? What am I missing? Also, the car is now making a ticking sound. Thought it was lifters although from further research it may be the cam phaser. Any input on this? Kinda sounds like it is in this video:

    Thanks

    You'll need to use a mechanic's stethoscope to localize the ticking sound but if you don't have access to one, a length of rubber hose could perform the same function.

    That sound could just be an injector going bad. Pull them and clean or replace.
    At 12 years and 85K, change plugs and coils. Make sure you have 1 or 2 piece spark plugs. If 2 piece, be very careful and do some homework on their removal.
    The throttle body should be cleaned every year at minimum, 6 months preferably. Do not use Seafoam. Ever! Oil of snake.
    If you plan on keeping it for awhile, it’s time for fluid changes in the trans and differential. When was the coolant last changed? Power steering? BTW, nice car. Almost as clean as my 05.

    I originally got ford racing plugs when I changed them on my 07 gt but the porcelain wasn’t affixed to anything and would rattle when I moved them. I quickly sent them back and got brisk racing 1 piece plugs and am happy with them.

    I don’t see how an injector would make that loud of a sound. They do click but not that loud. Its more likely cam phasers.

    Not to hijack but I disagree of what you say about seafoam. It might not be a miracle in a bottle but it does work.

    What’s in Seafoam that makes it do good?

    I’m not a chemist and won’t pretend to be one for the sake of arguing. Do some research and you’ll see whats so good about it.

    I’m not a chemist either, but I can use the internet.
    25% Cleaner>Naphtha
    60% Stabilizer>Kerosene
    15% Oxygenate> Isopropyl Alcohol (common Rubbing Alcohol)
    So, you have a blend of hydrocarbons and alcohol. Basically pump gas with a very low octane.
    This stuff is 100 year old technology which sells for over $50 a gallon. There are much better alternatives out there.

    Is this a consensus or a personal opinion? I’ve not seen it suggested on the 3V as a common procedure. I have never cleaned mine, almost 70k miles and 12 years it’s probably due but every year?

    Yes, if you want a smooth idle and instant acceleration. You haven’t noticed it because it happened so slowly, but both of those have declined over time because of a dirty TB and MAF.

    Just because its old doesn’t mean it doesn’t work. Thats like saying the gas engine is old so it doesn’t work anymore. And price is a non issue since 1 can treats up to 20 gallons, no need to buy it by the gallon.

    Great point, I guess it just never crossed my mind. Feel a little foolish for not even thinking about it! I had some pre-inspection maintenance planned for the next few weeks so I’ll just add it to my to-do list. Thanks for the info!

    You should also change the fuel filter.

    thanks for all the info guys. I’ve determined the ticking is the cam phases from all the videos I’d been watching and I already have a phaser kit in my amazon cart I’m gonna replace both of them for good measures. Was interested in a lockout but I don’t have a tuner yet.
    Pretty much from all my research TLDR; cam phasers were bad design from factory, most fail at low mileage.

    Aye right on. Black stangs are always clean. Except someone side swiped me the other day and I just got my new side view mirror in the mail yesterday. Now I got clear coat chipped on my rear quarter and a small crease in my door :(

    Can’t seem to find any websites that sell that additive except for random dudes off eBay

    Our '07 GT/CS convertible with 113K miles had the same tick. Was more noticeable at start-up. Louder between 1,500-2,000 RPM. Quieter under moderate load but louder when let off throttle. Eventually, it was loud all the time. Watched/listened to all the YouTube videos to try to match the sound and get a better indication of the cause. Doing a piston "bump-down" test indicated a loose #6 rod bearing. Pulled the engine and #6 rod bearing was spun. All the rod bearings and the right (PS) cam journals were scored. Cam lobes looked normal for the mileage. If you replace the solenoids and the phasers and still have the tick, dig into it deeper before more damage is done. We're currently finishing an engine replacement due to the repair parts costing more than a new engine. We are the second owners. Someone either failed to do proper maintenance or really beat on it.

    You should really look into the products you think work. Both Seafoam an BG-44 are mostly naphtha and kerosene. Naphtha is the solvent and kerosene is a carrier and is also there to add volume. Because you wouldn’t spend the $6-$7 dollars for the 3 ounces of naphtha that’s in a can of Seafoam.

    A few points to consider. Nothing dissolves carbon. Period. You can dissolve the gunk that it sticks to, but not the carbon itself. You can achieve better results using better chemicals like PEA. The active ingredient in Techron. There is another chemical that does a good job dissolving the gunk. Alcohol, both isopropyl and ethanol. It’s a great solvent and is doing a wonderful job keeping your engine clean all ready. And, That’s the only reason why Seafoam worked at all 60 years ago. It absorbed water from gas because it contains alcohol.
    If you feel you need a little extra cleaning, then add something that has been proven to work. PEA or alcohol. You can even get a can of toluene. That’s a great solvent also, and it’s used in gasoline to raise octane.

    Seafoam was originally made back in the 1940's for 2 stroke outboard marine engines. It's not designed to be used with 4 stroke engines. You need a Nitrogen based cleaner for a 4 stroke engine. Scotty Kilmer has a good explaination:
