So guess I did remember to seal the head bolts but when I saw what I thought was oil droplets in the radiator I questioned myself. However, I needed to adjust the valves anyway so really wasn't all that much time wasted and I found I learned something and wanted to post it for all that reads this.
If anyone needs to adjust the valves on 186 stock heads/cam that come on a 302 they should really follow the link given above at CRG. Just follow the steps and it works perfect. I found my damper measures 25.25 around cause it is kinda hard to measure on the car but using a fabric tape measure helps so you can measure each 90 degrees.
I hope I can still attach my next thread here rather then start a new one since it is kinda related. Sorry if it is in the wrong place.
Back to the main reason for this head bolt thread in the first place. The droplets I believe are from the orange GM Dex-Cool coolant that was in the car!! After reading a lot from this site it seems once air gets mixed with the dex coolant like it does on these cars it can jel up and create sludge OR what looks to be oil droplets in the radiator. My system is all stock including the radiator and not a modern closed system with a recovery tank like I believe now Dex-cool is made for.
I have flushed out the motor using the prestone super flush (Doesn't work) and ran many fill/drive/idle/drain/refill water cycles and I am getting all clean water draining out the radiator now and ready for the coolant (Zerex G-05 gold bottle) BUT I can't get the greasy/residue sludge coating that is stuck to the inside of the radiator etc... out of the system? Any advise? It is kinda hard to describe other than a slimy dark greasy oily residue. That make sense?
I have heard of using cascade dishwasher soap which sounds kinda funny and read an old thread by Dennis saying to stay away from any soap in the cooling system and like I said already super flush didn't work. There are no leaks and hate to take it to someone when I don't want too if I can do myself. The engine runs cool now just barely above the "C" and the heater works great. Should I just leave it and change the coolant once a year or should I be concerned.
By the way, this is an excellent site!!!
Happy New Year Everyone
