Have you checked on the oil sending unit? They like to leak at the top, or it could be valve covers leaking.
Hi Logan,
Russ is right. Check that nothing is leaking from the top and dripping down. The sender switch is in the rear as he said. Also, from the valve cover gaskets - that the return holes are clear under the valve covers. If not, it probably is the rear main seal (the Achilles Heel of the 429 CI). Good luck with it.

I am running Rotella T4 15-40 and it’s runs great-even in the winter. Its always has a bit of an oil leak, but getting a little heavier. Do we think this could be the rear main seal leak? As always,…Continue

Hey guys,
I have installed the same Edelbrock carb and have done everything the same as Jason’s carb and intake project. In the spring and summer months the car starts, runs and idles great! In the fall and winter months on a cold start, the car starts awful and wants to die until it warms up. I have to keep my foot on the throttle until it warms up or it will idle just terrible and try to die. Once it’s warm, it runs fantastic! Whats going on here? I was thinking of removing the…

While checking my Carter carb with engine running, I took the air cleaner off and there was a very loud hissing sound of air. I placed a piece of paper over the carb and it didn’t move up or down, is this normal?
