What is different with these items that make them not work with the Ecoboost setup?

Trav

  • The Modern Billet Chrome Oil Cap will not fit on the Ecoboosts due to the difference in size and thread difference.

So on these caps do you just screw off the old caps, screw on the new caps? What is the deal with the reviews I read about trying to get a pin in, and issues with that?

Anonymous

  • The washer fluid and oil caps are actual replacement caps. The brake fluid cap and the coolant reservoir cap are covers that adhere to the existing caps. The pin you are referring to is for the optional Modern Billet Chrome Oil Dipstick Handle that attaches to the existing oil dipstick with a pin.

When this oil cap first came out, there were reviews that said the rubber o-ring that the cap comes with wasn't right and that oil seeped out. They ended up taking the o-ring from the stock cap and using it on this one. Does anyone if that issue has been corrected? I'm about to install this and don't want oil on my custom valve covers. Thank you.

  • There should be no issues of oil seeping from this cap. It should be a perfect fit.

    Under-hood Dress-up for 2011 Mustang GT

    Absolutely top of the line quality! Pricy, but these covers really stand out. But, don't buy the dipstick T-handle because it won't work on the 5.0. The picture shows it on a 4.6. The rest of the covers fit perfectly.

    Review from Modern Billet Chrome Oil Cap (05-17 GT, V6)

    Great quality piece, but needs improvement.

    I purchased the 4 piece set for my 2012 GT, and all of them but the oil cap fit perfectly, and have no issues. After driving the car and the engine heats up, the oil cap slowly starts to twist open. The OEM oil cap is plastic, and fits much tighter in the oil port. I noticed the gasket on the OEM cap is a little thicker and seems to seal better. The metal cap is heavy, and the heat generated by the engine slowly backs the oil cap off. I noticed this because I saw oil residue all over the valve cover, and it was because of the cap opening up over time. The quality of the piece is excellent, but something needs to be done to be sure it can't back off. The factory plastic cap doesn't do this because plastic doesn't absorb heat like the metal piece.

    Chrome Underhood Dress-up Kit for 2012 GT

    These caps are fantastic! They look great and the finish is top quality. I was concerned about the oil dipstick T-handle fitting in the tight space on my 2012 GT, but it does. I did have a problem getting the tiny pin from the yellow OEM dipstick handle into the new Chrome T-handle. The OEM pin seemed like it was larger than the hole on the Chrome handle. It had to be carefully forced in and it took longer than expected. The other caps went on without any problems.

    MONGO LIKE. MONGO LIKE A LOT!!

    These add just the right amount of chrome under the hood. Not too flashy. I have not received any compliments, but that is likely due to the fact that I don't drive around with the hood open!! Yes, these are pricey, but this sort of thing is pricey even on eBay. But these stood out because of the writing on each cap. If on the fence, just do it. You will like the look.

    Chrome Oil Cap is Still Turning Heads

    Purchased chrome oil cap set which was extermely simple to install. This is one of those "Must Have" chrome extras that turns heads due to the unmistakable visability of the piece giving you more shine for your dime.

    Chrome Mustang Oil Cap

    The chrome oil cap along with the other chrome caps looks great. I have one complaint. The O ring that came with the cap was not thick enough and didn't seal the cap. I took the O ring from the original oil cap and now it works fine.

    The billet oil cap is a great way to start dressing up the engine compartment. Installs as a direct replacement for the oem cap. Graphis pop from contrast withe high polish of the surfaces.

    Very Nice!

    The Billet oil cap as well as the other Billet caps are very well made. The fit and finish is excellent. I continue to dress up my engine bay and these Billet caps really help are the final touches that it needs. The price is ok, a little pricy but for the level of quality it's worth it if your goal is to have a sharp looking engine bay.

    Looks great. Only problem is with the oil filler cap that has 5W-30 oil. The Boss 302 requires 5W-50. It would be better if manufacturer would offer center inserts for the proper oil spec.
