need help to ID oil leak
I am getting this 1950 Olds 88 running after sitting for many years. 5 years ago my Dad replaced the timing gears, timing cover seal, gaskets, etc, but he never drove it after that. This oil originally appeared to come from the front oil pan gasket, so I put some RTV on the spike where it was leaking. The leak moved to a spike above so I put RTV on that as well. The leak is now worse and maybe the leak is coming from the front face onto the pan gasket? The leak gets worse as you rev up the engine.
Where do you think this is leaking from? I have included a video link to my you tube below. I tried to upload the video but no luck with that yet. The video is 21 MB.

Sometimes a bad leak like that (and that is bad) will show up as a clean spot where the leak begins, that is if you haven't wipe the area clean in a while. Worth a look and the price is right.... Tedd

I'm no 50s engine expert, but perhaps he left off the oil slinger, or perhaps the harmonic balancer was severely scored and ruined the front seal. If it's the balancer, you might be able to get a machine shop to sleeve it.
An oil slinger for you car might be this:
USED 1949-1964 OLDS 303 324 V8 CRANKSHAFT WOODRUFF KEY AND OIL SLINGER 88 98 | eBay

Thanks for the response. I am also not familiar with these engines. I re-posted in the engines forum to see if it gets more views/responses.

It looks to me as though someone tried to remove and replace the timing cover without removing the oil pan first .
One might be able to do that on a Chevy , but definately not on a first generation Olds .
Looks to me as though the pan was badly damaged by the attempt to reinstall the cover .

You're probably going to need an oil pan .
The good news is that 1949 thru 1956 oil pans will fit .
According to the parts book ;

Well I have the pan out. I do not think the oil pan is damaged. Upon inspection, it appears those areas in the top corners are supposed to be shaped that way. The gasket has a right angle shape to it that exactly matches the oil pan. I do believe the leak was coming from the oil pan gasket not seating properly. There are also two tabs in the oil pan gasket kit. Where do they go?

Check that pan carefully . It looks like it has been bent and pried on .

Thanks...I have a new gasket and used oil pan on order. A side by side comparison of the 2 oil pans should make it obvious.

are they “glued” just using black rtv gasket maker?

But since you have done so , I would suggest putting a dab of silicone sealer there when you install the pan .
