I am a new member of the 348-409 group. I drive a '63 Biscayne, powered by a 409/425hp mill. It is clear from reading the postings on the 348-409 site that the members are enthusiastic and knowledgeable about their W-series motors.

Welcome aboard. Nice '63 you have there, and we just love the choice of engine. Tell us a little more about her, put up some pictures if you have them. And ask questions when you have them, there is quite a collective knowledge base here

Cheers!

Thanks for welcoming me aboard. I live in Salt Lake City, UT. My 409/425hp runs great. Nevertheless, there is oil leaking from the bell housing when she runs, but not when the engine is shut off and the car is standing. I suspect the cause is a leaky rear main seal. Is it possible (or adviseable) to replace the seal without removing the engine from the car? I am thinking that this might be an occasion to rebuild the engine.
The 409 oil pan is pretty much impossible to get off with the motor in the car. The crank counterweights are just to big. The GM shop manual also says the 409 needs to be pulled out.
Thanks very much, '62impala409.' The oil leak is annoying enough to inspire me to take on the rebuild project. The 348-409 group looks like a terrific source for expert advice.
Welcome, and as others have said, more pic's
cheers

Gorgeous car!!! Welcome!
Dear 4009envy,
I don't know the car's history. I bought it 4 years ago. The interior looks original. My guess is that the engine was rebuilt at some time in the distant past. The engine runs great, but the rear main seal leaks. For that reason, I am planning an engine rebuild. See my request for advice about a camshaft under "Builds and Projects."

Welcome W, If your thinking about pulling the pan one of the tricks I learned at the Dealer when they were new was pull the fan blades, the distributor cap & rotor, Starter & motor mount bolts, and turn the timing mark to 6' oclock. That puts the front counter weights up inside the block. jack it as high as you can. I've had to do it on my 09. Bugsy
Thanks for that tip, Bugsy. I have decided to pull the engine for a rebuild (when the winter weather here in Salt Lake City is over!).
