🚀 Enhance Your Engine's Performance with Mr. Gasket - 8016MRG Tdc Whistle Review

This whistle works great, no more 180 degree outs or guesswork. I used the correct size fittings from an old spark plug fitting compression test kit and have been in service. This is an essential tool for any gear head.

Finding top dead center yourself can sometimes take a long time and often you get 180. I made two motors within 30 minutes of opening the box and they worked PERFECTLY. 10/10 it is recommended to use at least 350 small blocks or 454 large blocks. It stops whistling around the TDC and you just have to align the timestamps. Exactly what I was looking for.

The problem isn't the whistle (which works great) or the TDC whistle concept. In fact, the hose is too "flexible" - if you shove it down a deep spark plug well, it just wasn't possible to screw it into the spark plug thread. In contrast, the spark plug air adapter that was part of the leak test kit screwed nicely into the same spark plug wells. I ended up using an endoscope to visually check the OT and now it's garbage. If you have plugs that aren't countersunk this might work for you…
