Leaky 4x4 pan fix
Hey there,
My new 390's taking longer to get in than expected due to holiday shipping delays, but in the mean time, I bought a premo fe 4x4 pan (one on my truck has had encounters with many a rod and large rock). I want to know what you guys have done to fix the inherent leaking problem with these pans besides slather a pound of RTV on it. The one on my truck leaks like a siv around the dipstick bung. I was thinking about cutting the dipstick bung out of a chev big block pan, welding it in and using a chev dipstick as they have an O-ring seal or drilling rivets out, eliminating the gasket, plug welding through the rivet holes and silver soldering it up. What do you guys think, any other ideas?

oil leaks
Dustin, are you sure that you really need to fix anything ? Maybe the old pan leaks 'cause it has been bashed with rocks a few times. My truck has its original '71 pan on it and it does not leak at the dipstick tube. Maybe the swap to a new pan will cure the problem. DF

I have had two different leaky 4x4 FE pans that I had to drill out the rivets holding the dip-stick socket and replace the gaskets with gasket material and a minimal slather of RTV. I then just used short bolts and double-nutted them to be sure they stayed in place. There doesn't appear to be any need for O-rings or other RTV after doing that.
Good Luck, Steve
