A few years ago I replaced my intake manifold on my 283 with an older style one from 57. I had the manifold off for a couple months while i got around to replacing it and all the gaskets on top. It was in the garage but open to the air most of the time.

After getting it back together I ran it a few weeks off and on and then noticed that in the oil filler tube there was some pure white gel amost like vasolene but not as thick. I cleaned what I could out. I have not seen it since.

I am wondering that caused it. Is that a indication of water in the oil?

Possibly a leaky water gasket leaking water into the oil?

I am not seeing any smoke.

I did not have a PCV valve on it as the original 57 had the road tube and the version of the 283 I have expected to have the PCV valve in the valve cover but I put the old style on when i put the old intake on so there was no place for a PCV valve.

So I assume that it had a bunch of presure and it was venting out the oil filler tube vented cap I was using. Although it was not visibly smoking.

But I think I got some oil spray on the engine and firewall.

Since then I have put a PCV off a small hole in a stud that goes through the intake manifold back by the coil. It was a stud that use to be holding the carb on. Not sure why it had the hole thru it. What was that for?


But I am not sure that is a big enough hole to work well for a PCV valve. I have not seen any more white goop but it seems that the vented oil filler cap may be plugged up with goop. I will have to wash it in some kerosene or soething and see what that does when I get it all back together again. I am still finishing up rewiring and repainting the inside of cab and firewall.

I also need to work out a better PCV valve solution. I have seen a few on here. I just need to implement one.


But is that what caused the White Goop, blowby or is it water in oil or just moisture in the oil from being open to the air for a few months and not running?


Any ideas?
