Help pistons number 2 not coming all the way up a little off
 

Ok I pulled my head and there was antifreeze in the piston cylinders well it was a blown head gasket caused by putting the same headbolts back in after changing the head gasket the first time well 1 and 4 pistond come all the way up top dead center (tdc) i turned it so 2 and 3 would do the same but 2 was just a little shy of 3 which came all the way up tdc but 2 didnt come as far its just a little down do i have a problem is it a bent rod PLEASE help?

[align=left]Bent rod? There's no rods here, it's overhead cam. The pistons ride on the crankshaft, just like any piston car. As to why it doesn't come all the way up... maybe it's designed that way. I don't really know. Which model and year is it?

Yes

That's what I think. Too much fluid (which does not compress) leaked into #2 and forced a hydraulic lock on a compression stroke. Could also be a deformed wrist pin, but either way, I think you are looking at a rebuild situation. You could slap a new head gasket on the engine and see how well it runs, but rod, wrist pin or piston problems usually manifest themselves pretty quickly. I don't know what condition the block present is like, but if the rod breaks and punches through the side then you are looking at a whole new motor. Also, you didn't say what condition the head is in. A blown gasket quite often results in a cracked head casting. I'd inspect the head thoroughly.
