What are the most common problems with the rotary engine in the 2008 Mazda RX-8 Sport?

Question

Accepted Answer

Hey there! Great question about the 2008 RX-8's rotary engine. Based on my research and what enthusiasts consistently report, here are the most common problems with these Renesis rotary engines:

**1. Apex Seal Failure** - This is the big one! The apex seals are like piston rings on a regular engine, and they're considered a wear item. When they fail (which is almost inevitable), you'll get loss of compression, power loss, excessive oil consumption, and blue smoke from the exhaust.

**2. Engine Flooding** - Rotary engines are notorious for flooding, especially if you don't let them warm up properly or if you do short trips. The factory has a "deflood" procedure, but it can be a real headache.

**3. Oil Consumption** - These engines are designed to consume oil to lubricate the apex seals, but excessive consumption can indicate seal problems or other internal issues.

**4. Ignition Coil Failure** - The ignition coils on the RX-8 are known to fail relatively frequently, which can cause misfires and rough running.

**5. Catalytic Converter Issues** - A clogged cat can cause performance problems and even engine damage if left unchecked, partly due to the rotary's unique exhaust characteristics.

The good news is that your RX-8 has a documented service history on CarFax, which suggests it's been properly maintained - that's crucial for these engines. Regular oil changes, letting the engine warm up properly, and occasional high-RPM runs (yes, really!) can help prevent some of these issues.
