Carbon deposits are one of the biggest problems with rotary engines. All internal combustion engines face the problem of carbon deposits that are produced when burning gas.
Due to the long and uniquely shaped combustion chamber, the engine’s thermal efficiency was relatively lower compared to piston-cylinder counterparts. This also often resulted in unburned fuel exiting the tailpipe (hence the tendency of Wankel engines to misfire, which is obviously as awesome as it is inefficient).
On average, it costs about $5,800 to hire a mechanic to rebuild your RX-8 engine and about $4,400 if you buy the parts and rebuild it yourself.
These apex seals also typically don’t last long before they need to be replaced. Rebuilding a Wankel at 80,000-100,000 miles is typical and earlier than most piston engines require such exhausting work.
Rotary engines rev up and can produce a lot of power in the right hands. They’re easy to mod, customize, and build, and you can use them to build a fast car fairly inexpensively.
Rebuilding a rotary engine is actually quite easy, much easier than rebuilding a traditional piston engine, basically you build from the bottom up by layering parts on top of each other. Well, there’s a lot more to it than what I just said, but those are the basics. if you’re a little mechanically inclined you shouldn’t have a problem.
If something goes wrong, a rotary engine can explode in a really scary way. A few days ago, during a raucous exhaust contest at the Rotary Revival 6 in Sydney, Australia, a Mazda owner thought he was wowing the crowds with his incredible Wankel engine, reportedly revving up to 10,000rpm.
The average cost of a Mazda RX-8 engine compression test is between $88 and $111. Labor costs are estimated at $88 to $111. This range does not include taxes and fees and does not take into account your specific model year or unique location. Corresponding repairs may also be necessary.
The cost will depend on how you want to approach this project, but it should reach around $10,000.
As with any engine, if you take the time to look after it properly, it will last longer than usual, but that can mean 80,000 miles or less.
At Classic Mazda we want more people to know that we still supply rotary engine parts and that these can be purchased at any Mazda dealer worldwide.
The problem is that there are so many different ways that an engine can fail: Excessive carbon deposits accelerate seal wear and cause loss of compression (particularly a problem on automatic RX-8s). Excessive carbon deposits loosen the seals, causing loss of compression (particularly a problem on automatic RX-8s)
