How to remove a piston through the exhaust port

I had a blown head gasket. Removal showed my rear head on my 69 kaiser M35 had cracks in all cylinders. I found two new style heads (they have a valley between the valves verses flat) and found they had a problem. The first one was mouse related. Lots of pee and corrosion in several intake ports completely stuffed with millions of seeds. A little phosphoric acid and it was fine.
The exhaust manifold came off and there poking up out of a port was a bunch of sooty aluminum. The cylinder surface was beat to heck. I could not look close since it went from bench to truck quick on a forklift.

Kinda funny. Never assume it is ready to run. Not sure why I don't get pictures. I have the IMG in the edit mode but still shows a link in real time.








The machinist found some pretty big issues. I am glad I took in my cracked head for some donor valves.





The finished cylinder. This guy is great. He said he picked aluminum out of the port walls with a dental pick.



Now I need to install them.:jumpin:

I saw an RD400 2-stroke mororcycle do that at night. He as going 75-80 mph and the sparks were 150-200' long. The piston lasted about 30 seconds . . .

I don't know Gimp. But it keeps the heads from cracking. Recovery4x4, My motor was fine except the head gasket and head cracks. I had not planned on anything else. I just did a rear main, all new clutch. I had all the intake and exhaust off a while back. My LTD is a good sound motor. It actually pulled and ran well. I want to get it running strong again and then swap in my LDS.

Sure looks like the mouse was chewing on the valve. Must be one tough mouse.....:mrgreen:
