It's me again. I finished taking the top end of the engine apart yesterday and found out that I had 6 of 16 valves out. I went ahead and ordered all valves since I already have the engine opened up. The head gasket looked good and the head was perfect, no scratches or cracks, thank god for small favors. So now, my question is, I assume that the valves went because the cams were 180 degrees out, right? My crank shaft turns without resistance. My pistons raise up flush or just a hair under flush with the block, is that what is supposed to be? They were dirty, looked like burnt oil and fuel, was told that is what is supposed to be like and that is what is was, does this sound right so far? Cleaned the tops of the pistons with a rag to get the gunk off, came of pretty easy. Didn't see any damage to them what so ever, not even a dent or scratch on them. So, the big question, the valves should be okay right and they all raise to the block flush two at a time of course, any damage maybe to the rods? Honestly, I think I would prefer you lie if you have to and say they are okay, but I don't want to put this engine back together just to find out there are more problems with the rods or piston. Kind of afraid to take the bottom half of the engine out. How about the rings on the pistons. There isn't really a way of knowing unless I take the pistons out and the means taking the bottom of the engine apart. Please advise on my questions and any advise would be appreciated.
Thank so much
Johnny
