Overall Assessment

Customers highly appreciate our product for its quality, usability, and safety features. It is praised for its straightforward and easy installation process, fitting perfectly without need for additional bolts, nuts or washers. A key feature is its ability to effectively seal motors for vacuum pumps and aftermarket valve covers that don't have oil fill caps. The product holds up well with great material quality, showcasing good looking finish which adds aesthetic value. Its practicality is favored by users who find adding oil more convenient and time-saving, without worrying about leaks or baffle obstruction. Furthermore, the set screw lock ensures extra security, with the product capable of being a simple and effective solution to various engine setups. It's also well-suited for adapting on fabricated aluminium and alloy covers with minor machining. Customers highly recommend this product over other market staples and plan on repurchasing it for future applications.

Perfect solution

Inwas very turned off to the idea of pulling a breather to put oil in my new motor but this thing is the answer. Took me all of 15 minutes to install in my new valve cover using a knock out set. The finish is exactly what I was looking for.

I had to mill my Mickey Thompson cast aluminum valve cover to make it work. I called the manufacturer and they said it was designed for the fabricated style covers. Your ad says fits any valve cover, which it does, with modification. Luckily I have access to a milling machine. Even with that it is a nice product.

I would definitely buy again. Great seller.

Have used this product on almost every build with valve covers with no holes in them. You can put the oil fill anywhere you want, and it also seals up the system when a vacuum pump is used.

Install was easy and straightforward. I used red loc-tite on every thread just to be safe. Looks great. It will still be a while before I actually turn the engine over so I can't comment on how it performs.

This cap was for sealing up my crankcase for a vacuum pump. The existing breather tube hole was the same diameter as required to install this cap. Worked out perfectly. I like the set screw lock that this has for extra security.

Would Recommend

Plug works as good as it looks.
