Attachment 59899Attachment 59900Attachment 59901Attachment 59902I hope that it worked I tried to attach some pictures, the oil port I believe you are talking about is the one that I have my oil pressure gauge plugged into at this moment. Please let me know if we are on a different page on this as I have been known to miss an oil galley plug here and there.:oQuote:

A couple drops of oil on the threads of the brass fittings will go a long way to guarantee a leak free fitting.
Well, I went through the same thing and guess. what??/ duhhh No gas . fired and found out a full tank of gas went into the night. ( stolen. ) only need three things ign and o2 and petro.
Keep us posted on the leaks, good thread with lots of usefull info. Personaly I've also had good luck with the black RTV for my 460 big block. Only time will tell though! :)
On the assembly line at the Chevy V8 engine plant in Flint MI we used a product called Threebond. I’ve never seen it sold in parts stores any place, but that’s what GM used to seal the "China Wall.” (Tech, thats the first time I’ve seen that term used outside the assembly plant! It takes it’s name from it’s resemblance to, you guessed it, The Great Wall Of China). We also used guide pins to align the bolt holes in the intake with holes in the heads. The pins also held the gaskets in place. As was stated earlier, this only works with intakes with vertical bolt holes. The Threebond was applied, intake gaskets were set into place with the ends set into the wet sealer and the intake was set in place immediately. Engines that sat for more than five minutes (such as when the line was shut down for break time or lunch period) had the already applied sealer, (applied by a robot) removed and reapplied by hand prior to dropping the intake manifold. The engines were in the test stands and being fired up within 2 hours after assembly.

This one has deffinatley been a learning experience for me.
one time I tore down a sbc that had silicone on the China wall. there was a chunk of it stuck to the screen on the oil pump pick up. Not enough to hurt anything but if it is inside it will go to the bottom.
If you let the silicone completely cure (24hrs min.) before you fire it up, it will not chunk, flake or otherwise cause problems.
bringing this back from the past as it has some excellent info at the right time for us
cheers
