Compresion Check/Rebuild Question
How important is it that a compression check be performed by a rotary specialist? Can a decent piston engine mechanic make the check and give reliable feedback? Also, what are good, acceptable, and un-acceptable readings for an 87 turbo. And lastly I did speak with a reputable rotary mechanic today and he indicated that TII rebuilds generally run about $2,500 to $3,000.
Is this accurate, it seemed like a lot of money but the guy has a pretty good reputation. All feedback appreciated. David

The reason they can't check your compression acurately at a normal shop is because the rotary requies a special tester that most normal shops don't want to invest in(about $1600, if I remember correctly). The rebuild price can fluctuate(sp) depending on what you want done what is damaged internally, and who does the rebuild. Shop around and see if there is somebody better and less exspensive than just the Mazda dealer near you. Since you're located in Florida then there is most likely a rotary specialist in your area or atleast close by

IF you just want to get an overview of engine health, you can run a normal compression check on each rotor for a reading which represents the highest of the 3 faces per chamber, which is usually the same as the other 2.
IF the apex seals integrity are in question, youll need to hold in teh valve on the tester and observe the needle bounces. Uneven bounces or nonexistant bounces indicate broken/cracked apex seals requiring rebuild.
