Small update on my Rx-4. The car has been pretty flawless except for the engine smoking more than it should. After 46 years I'm thinking the oil control o rings have probably dried out and failed causing a lot of oil to get by the oil control rings. Engine still makes great compression and starts and runs everytime you hit the key. I have build a fresh engine to drop in the car though using a spare engine that I had. I'll swap it out for the original engine and then tear it down and freshen it up as well
