Seeping New head gaskets
First some background on the engine. Original 1969 YS block and 62 heads. Shortblock was rebuilt in '97. Heads were ported, polished, gasket matched, valve job, new rocker studs and springs a year earlier. The rebuilt combo lived happily in the GOAT until 6 years ago when I took the car down to the frame. I had the heads worked on again, this time RAIV rocker studs, hardened valve seats and new springs. The short block was left alone except for a new cam and chain and a new rear main, then soda blasted to clean it up for paint. I used ARP head bolts and the same part# head gaskets that were on before. Neither the heads or block were milled. I am ready to fire it up finally. It would've fired up last weekend, but a bad coil fried my ignition box when I was trying to set static timing. I added one gallon of antifreeze and filled the rest with water. The thermostat and water neck are not on yet so I could make sure the water level was at least as high as the T-stat.
Now here is the issue. In the week since adding water both head gaskets seem to be seeping along the outer edge under the headers. But it is not clear water, it is different colors. Some spots are yellow, some are greenish, and some are brown. And some of the drops are stuck half drip, like whatever is mixed with it has enough surface tension to hold the drop. I can touch them and they drop like normal.
Anyone else seen anything like this with new head gaskets on a known engine? The correct answer should be..no problem at all, it is just a reaction between the soda and being grounded to the battery and the rapid weather changes lately here, its condensation....right? I really don't want to take the heads off again.
I am going to put the t-stat, water neck and upper hose on this weekend and pressure test the cooling system this weekend to see where it is coming from.
Whew...words, words and more words.....
