Hi Folks,

I'm in the process of rebuilding the 390. It's going slow mostly because the previous owner didn't do a good job of labeling bolts, nuts, etc. when they disassembled the engine, not to mention the number of fasteners that are missing!

Question: Does my engine have an oil slinger or a windage tray? I looked at Jason Edge's engine rebuild photos and it appears that the answer is no for both but I don't want to button things up until I know for sure.

Thanks Russ. That sounds like a windage tray to me but I wonder if the 63 had one?

The 64 pan has a baffle, to stop oil. A windage catches oil and stops it from turning to a froth. I've got a windage in my 496 Tahiti jet boat.

- Most 1963's I have pulled in had a separate oil pan baffle as noted in 1965 Master Parts Book scan below.  I have also inserted pictures of the 1963 baffle.
- In 1964 there was a baffle that was integrated into the bottom of the oil pan and only intermittently used during the production year as noted in the April 1964 page 21 Serviceman Bulletin below.

Thanks Jason,

My oil pan looks like your last photo and I didn't find an oil pan baffle in my parts. So I guess my question is, should I be tracking one down?

after looking at these, i think I might have a baffle after all.

Be buggered huh. 

My car has number 055288. So outside the range according to the Serviceman. It does not have a baffle and there is nothing indicating it ever had.

Personal choice, but if you like to launch your car off the line, I would suggest a baffle.    I have an oil pan with a baffle if needed.

Just send me an email;  russ85747@hotmail.com     I'll be away for the week end and will get back with you on Monday.

Yes I have the same oil pan integrated baffle. When I changed the seal on the pan it took me a few seconds to realize what was holding the pan on after I was only able to drop it an inch or so. The engine was in the car when I did this. 

Thanks everyone. I'm going to dig through my parts pile one more time to see if I can find it. If I don't, I'm not going to worry about it.

64 Recirc/Fresh Air Door Actuator replaced; FROM THE INSIDE.

Posted by Norman Silverman on February 4, 2019 at 11:21pm 8 Comments

I am happy to report that I have successfully replaced the Fresh Air/Recirc door actuator that is located on the blower box-and have done so without having to remove the blower box. I did it by taking out the glove box and attacking it from the back.  It took several days, LOTS of patience and some band-aids, but it is done. THE most difficult part -BY FAR- is to remove and then replace the screw that sits on the actuator arm, connecting it to the fresh…

Where do the flashers go in my 64 Deville Convert.  I'm thinking that's why both turn signals stopped working.

Where is the best place to purchase good quality motor mounts/trans mounts for my 1964 SDV? I see that Rock Auto has them for $8 and change, and others for $24 and change. Big difference. Is there a better place to buy them from?
