Mazda Rx8 Compression Test
November 19, 2008 · Print This Article
Find more about the Rx8 compression test and how to perform it. To run this test you must have two special mazda service tools: 49FO-18-904 and 49-FO-18-901.
Each rotor should be tested for compression, and the final results must be compared to determine the engine condition.
i work at a used car dealer and every rx8 we have delt with is a turd. i just wanted you all to...

The number one issue with most Rx-8s is the number one issue with most cars….THE OWNER.
I have a 04 Rx-8 with 104k running OEM motor from day one, thing is though. I don’t treat my rx-8 like a civic, it demands respect much like you would treat a Porches. And in case you haven’t owned one, they are B****es for breaking down without proper maintenance.
Deployment guy, you probably didn’t rev up your motor to 4500 *like it says in manual* to expel gas from cambers. Its not a piston, the seal that keeps compression is always exposed. So letting a rotary sit is a bad idea. Either fill it up with storage oil and let sit, or drain completely and store where seals wont be bothered by elements.
Problem 2. Its a rotary, redline ONCE a day or every two days. The carb. build up is ON the seals in the engine, if you grandy it too much it will wear out the seal. Duh, drive it like you own a pair.
Problem 3. The engine is designed to burn oil, check it every 2 or 3 gas fill ups. Don’t use sythic oil as it doesn’t lub the seals correctly. period.
Problem 4. Just because you work at a car dealership or built a b16 in your moms garage DOESNTMAKING U CAR MASTA! Each engine and car are different. For people that had their shit go bad its usually their fault. They want something that looks cool but none of the responsibility that goes into it. My rx8 makes 221 whp and runs like a champ. But I know how to take care of her. Remember people, the MOST registared and DRIVEN old car on the road in USA is the 1st gene RX-7. They just dont die until 300K++++. Case in point none of these idiots know what they are talking about. Fixed.

I had my car sitting around while I was working overseas.
Came back, changed the battery over because it was dead and tried to start.
Started for 5min before it cut out.
Had a check done on the car and was informed the engine is “misfiring at random” by the diagnostic tool which the mechanic had.
Coils and plugs were replaced hoping that was the issue but nooooo… still causing issues…
since its out of warrenty… i’m up for big money to get it back on the road….. what a waste!!!!!

own rx8 mazda 54 plate has not started since november 2010 new plugs new leads new battery nothing sick and tired of mazda ignoring this major problem with rx8 flooding and lack of compression they wont do anything about it . ITS a major problem with rx8 2003 to 2005 . IN america they had to recall them and replace the engines. Trouble is it doesnt really start till warrenty has ran out or in my case just over 60000 miles. Someone did say to me when i first bought it make sure you get rid before you hit the 50000 miles after that they are scrap.
Mazda burying their heads in sand not willing to help these people who have spent hard earned and saved money on their products , they should be sold with a warning after 60000 car is worth nothing cars wont start unless you purchase a new engine, which will probably wa cost more than cars worth.What a SCAM no one wants to know my car is sitting on my drive looking pretty but WONT START, HAD TO SORN OF ROAD CANT GET TO GARAGE TO MOT IT SO CANT TAX IT ITS A TOTAL JOKE 15000 grand on a piece metal that wont work NOT FIT FOR PURPOSE
