sdsurf Posted March 30, 2008 Report Share Posted March 30, 2008 Looks like the exhaust valve was hitting the piston. thoughts? pics in the AM (sunday pac time) Quote Link to comment
datsunfish Posted March 30, 2008 Report Share Posted March 30, 2008 If the valve is bent up it probably got seized due to wet storage or age.Was this that seized motor? Quote Link to comment
sdsurf Posted March 30, 2008 Author Report Share Posted March 30, 2008 no this is the good one (at least I think it is good, turns over smooth) Quote Link to comment

datzenmike Posted March 31, 2008 Report Share Posted March 31, 2008 Looks like the exhaust valve was hitting the piston. thoughts? number 1 piston That's the intake. The smaller marks to the front are the exhaust. I doubt that it's just chance that the #1 and #4 hit the piston tops. When put together the crank was 180 out or the cam was. Soon as it was turned it hit and 'seized'. Seen a lot worse that ran fine, including a machine screw embedded in a piston top. Pulled it out, new HG and go. Quote Link to comment

yello620 Posted March 31, 2008 Report Share Posted March 31, 2008 I think that Datzenmike is saying that as they were turning the crank to #1 TDC to install the timing chain on initial assembly, that the cam was turned just enough to cause this interference and temporarily seized the motor until the cam turned which changed the valves. I dont see anything there that i wouldn't reassemble. Put a new headgasket on it and go. Jason Quote Link to comment
datzenmike Posted March 31, 2008 Report Share Posted March 31, 2008 Yes, if not the seized one then what Yellow said. Quote Link to comment
