As I continue to research engines of vehicles I may buy in the future. I keep learning new things.
1. Toyota A25A-FKS has a oil separator similar to the Mazda Skyactive-G, so no catch can should be needed.
2. It has a electric motor on Intake Valve camshaft that speeds up or slows down to vary intake valve timing. The electric motor seem to beholding up so far, haven't heard horror stories yet, even has a failsafe mode to safe engine if it fails.
3. Electric motor coolant pump on A25
4. Really like the D4S injection system, I think Ford is the only other Maker to use a dual Port/ Direct inject system. Also learned the noise that everyone complains to Toyota about when they accelerate hard is when the engine starts using the Direct Injection.
5. You have to take the freaking intake manifold off to replace PCV valve.
I really like the D4S injection design, The Piston on the A25 looks like normal piston much different then the Mazda piston with it's cup in the middle I wonder which engine is the better design?
