Hey all,

I am in the market for a rotary compression tester, and I noticed that they have plenty to choose from nowadays aside for the oem testers, but I have decided to keep an eye out for the OEM compression testers.

My question now, is $785 worth buying a Mazda OEM Compression tester??? I noticed that brand new can range from $1800 to $2300. Im just having a hard time deciding, maybe someone can chime in. Different people will have different opinions knowing how fat or empty their pockets are, but hopefully the die-hard wankle guys can chime in as well.... You can always count on an OEM part for quality IMO.





Thanks!

As you mentioned, there are several aftermarket rotary compression testers available for significantly less than the old OEM boxes but I've no idea of their performance. They look a lot more sophisticated though.

The one shown is not old. The old ones had a mechanical stylus that traced the curves onto a piece of paper. Electrical current ran through the stylus and burnt a trace mark on the paper.
The special paper was expensive and is most likely not made any more.

Okay, what you're describing sounds properly ancient. 7 segment displays are still old though :P

You know it just hit me randomly today that, regardless the price, I think it'll be a great investment. I'm always concerned about how my engine, so I guess it would add reliability.

Thanks!

At any meet, you could easily get $25 a car for doing a compression check. Could pay back pretty quick.

That doesn't sound like a bad idea... Haha
