INNOVA 3614 Compression Tester Plus - 6 Piece Kit

I don't have another gauge to compare it to, but the compression numbers I got on my test run this afternoon were pretty close to what I expected. With the exception of one cylinder, which makes up approximately 65% of the others. I had considered renting a similar meter in my area, but it had received poor reviews due to its inaccuracy. br>br>However, I had to deduct one star because of this. If I had the option, I would have given this 312 stars because the instructions for using the solid extension were far too ambiguous. Is it just supposed to be held in place in the spark plug hole because it only has a rubber tip and no threads? I was able to use the hose's threaded attachment for the spark plug holes, but I struggled to keep the adapter screwed on. Because the 14mm threads fit perfectly, I decided to do the compression test without the adapter. br>br>However, it was the gauge itself that fell short for me. The needle was past the "0" mark and the pointer half of the needle was slightly inclined for some reason. With a plastic scraper, I was able to remove the meter's front face (which was steel and pressed on tightly). I straightened the pointer and reattached the front face after lifting the needle back to the right side of the post, and it worked for me. Aside from that minor snag, everything is well-made and durable.

I'd never done a compression test before, but it seemed straightforward enough, so I watched a few videos and got to work. It was simple to install and connect this tester to my vehicle. The gauge is simple to read, and the hose appears to be in good condition. It has a pressure release valve, which made switching from one cylinder to the next a breeze. However, making sure it was securely fastened was a little awkward. You twist the tube, but only the braided outer part moves, while the inner tube remains stationary. To read the pressure at first crank or if it isn't holding pressure, you'll need help from another person or a camera. It was too short to lean against the windshield and read while driving. br>br>Overview: br>br> It's a simple compression tester that does the job.
Pros: br>Easy to read gaugebr>Easy to usebr>Extra fittingsbr>Pressure release valve for quick and safe disconnect Unless you're doing it with a friend, you'll need a camera to set the pressure at the start of the crank. br>The steel braid feels like it might break early on, but I don't think the pressure tube will break. br>br>Conclusion: br>br> It was money well spent on a reliable piece of gear. With this, I was able to perform a cursory engine health check, which should help me diagnose any future issues.

The tool works well and can fit into small spaces. The only way to tighten the fitting that screws into the spark plug hole in some tight spaces is to apply torque to the flexible braided hose. While the braided hose is strong enough to hold the fitting in place, I'm curious how many tightening and loosening cycles the hose can withstand before the flexible steel weakens and ruptures. br>br>A well-designed carrying / storage case (not included) would add to the value of the item.

The gauge is extremely unreliable. I thought I was having issues with each motor until I compared them to two different gauges that were known to be accurate. If you're looking for an accurate gauge, stay away from this one because it was reading 100 psi while the other gauges on the same engine were consistently reading 150 psi. br>br>While the tester appears to be of high quality in the pictures on the internet, it is made of a low-cost steel mesh that easily distorts and snags.

It was used to check compression in my son's small-block Chevy. None of the fittings fit his sockets, so I just used the straight fitting with the rubber end and pressed it into the sockets while he turned the engine; it worked fine, but the fitting punched through the rubber end about halfway through, and now it won't stay on. It's not a huge deal because I can probably just super-glue it together. Also, the face is covered by a plastic piece, not glass, so glue it on the fitting and you'll be fine. I accidentally poked my finger through that one about 5 minutes into the job, but it still works. A glass face, thicker rubber, and a carrying case would improve this kit, but it met my needs and I'm satisfied.

Believe me when I say that I had a Triumph engine that I did everything except check the compression on. With an unknown non-starting engine that had extremely low compression, this should have been the first thing I checked. br>Nice build! I got it because of the metal hose, but I'm thinking about switching to rubber (the metal could scratch your valve cover if the spark plugs are buried deep). I've heard of the attachments on other sets coming off and getting stuck in the head, which would be bad, just like the brass fittings. This unit, on the other hand, hasn't had any such issues. Get a set because it includes various sizes of fittings and you won't have to buy them separately later. It was installed on a Triumph Daytona 600 from 2004.
