So I need to take the piston out and take it to a machine shop so they can see the exact specs on it? Or do I need to take the whole thing cylinder included?OK....most obvious...no blown head gasket...the 3rd, 4th and 5th pictures show the inside of your cylinder and the position of the piston in it...if you notice in picture 4 is where you can see it best...the piston is off center...in my opinion, you need to bring it to a machine shop and have them use a device to measure if that is excessive wear...can't really see enough of cylinder wall to see if it is scraped up.....but it looks like you need new rings at a minimum and possibly need to bore out the cylinder if it is not past tolerances...if you got this apart this far and are confident you can get it back together...you should be able to do the rest of the job other than boring out the cylinder
The valves are very snug, should I mess with them or just clean them up? Or to really find out do I need to go ahead and pull those?
Quick question, which might be stupid, to get the piston out do I go flywheel down to do that? Thank you guys for the help.
