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

Hey Buggy, is that the engine I sold and shipped to you about 10 years ago ?

No it's not, but the engine you sold me is still going strong in my old grey Rx4 as far as I know. That's the one that I did the half bridge port on and is running the twin Weber 36 dcd carb setup. Put down 203 rwhp. It's out in Alberta now.

You have my old grey 1976 Rx-4? Good to see the interior getting some love. The dash and seats look good.
