🔧 Innovative Products Of America 7880 6-inch Long 14mm Thread Top Dead Center Indicator, Black Review

when i ordered it i asked if it fits ford 302 when it arrived the package said it only fits hemi engines called the manufacturer and he said to be very careful and it should work and use common sense? That's the answer he gave me.

Rolled on my Pontiac 400. My spark plug holes don't line up with the movement of the cylinders and it jammed when cranking the engine by hand. Great quality and I'm leaving it because it's great for an engine with pistons pushing right up to the spark plug.

Worked on my Ford 302 if you are careful and drive slowly. I also lubricated the tip before inserting it so it slides over the top of the plunger without damage. I didn't see it was only HEMI until I saw it on the box! Maybe I can use it as a pogo stick for my hamster.

This 14mm tool is great for finding top dead center. First, I put a whistle in the spark plug hole to determine the compression stroke. As soon as it whistles I use this indicator to find the exact top dead center. The ideal tool to prepare for a bottle leak test.

This tool will work as long as you use it on pistons that line up with the spark plug holes. Slowly cranked the engine by hand and it showed me where TDC was on the engine, but upon removal the tool bent and I cranked the engine very slowly. I will not buy again

First off, what the heck is "transparency"? Save money. The thread will not fit a 14mm spark plug hole in every car I own, whether Japanese, American or German. Maybe it's a Whitworth thread or something. Too bad, seems to be of good quality. Looks spectacular in my crib. Otherwise it's useless. I had to go back to the soda straw.

Love it, I work on standby generators and constantly adjust valves in the field. That is God's mission. I know the cylinders are exactly where they need to be for proper adjustment. Screw side turned with changed markings that cannot be erased in 1/8" increments (very important for compression exhaust engines). I just want the tuba the instrument was in to have some sort of lid.
