original motor inspection.

Recommended Posts

So finally after 3.5 years of ownership I am finally going to disassemble, clean, inspect, and reassemble the matching numbers motor to my 1970 GTO. I am curious as to its story and its a chance to give my youngest son a bit of engine 101 of his own. I've so far got it down to the short block but still no rotation of the crank so far. I think the pistons are rusted in the cylinders and just need time to soak. Haven't seen any glaring damage except a well bent push rod.

Poor Pistons.....Justa like ours, out of the playoffs early.

So went on a marathon reassembly of the motor on Saturday morning with a good oil down of everything and got the motor back together and painted in 5 hours. I feel like I've been run over by a Mack truck, lol. All I found was a bent push rod and a broken ring land on a piston skirt. Cylinder #2 had enough pitting in it from rust to keep the rotating assembly from turning over.






and now back to the rear gears and headers install.
