Hello,
After driving the car around after a rebuild, I noticed some black oil dripping out from above the #2 freeze plug (74 200 block). So we pulled the head, noticed the bolts were loose and tightened them back up. After, noticed that it was stilll leaking and saw it leaking water just below the #2 spark plug (and water in the oil). Then I read if the head has been milled significantly, washed may need to be added to head bolts since they would be bottoming out. Fairly sure this was the problem. SO pulled the head again, added the washers. Seemed fine. Not as much smoke. THe next day, it started leaking from about the Freeze plug again. The block was checked with a straight edge to see if it was true (it was). The head was professionally rebuilt, twice (how the washer idea came about). So, I am stumped as to what else it could be. I don't want to think about a cracked head since it was rebuilt. Any other ideas?
Thanks!
