How to remove a piston through the exhaust port

[Kaiserjeeps]

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.

Its about time you got something done! What does the valley between the valves do?

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 . . .

Replacing all the holes as well?

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.

Gimp, your truck looks like a dog looking for a scratch.

Well done man!

Al, that is the best description of what Chris' truck. Priceless.

I have been trying to to think of a good nickname for him or his truck. Just give me a little more time.

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