Deutz Allis 5215 overheat when mowing

No doubt replacing the head gasket and milling the head if necessary is the right thing to do. You might try some Bar's leak or other cooling system sealant until you can get to it. I put it in a Toyota Corona once that had a leaking head gasket. My daughter drove the car for several years with no problems after that and I never did bother fixing the head gasket.

The head is at the machine show now, was a bit warped, getting milled flat, pressure tested good and no cracks. New head gasket will be here late this week. Mike

Started putting her back together tonight, taking a break right now to watch the news and eat. Hope to start her up in a couple hours. So far I have the head torqued down, valve train installed and lash adjusted, injectors reinstalled, lines tight at the pump, loose at the injectors for initial bleeding. Need to install upper rad hose, fill the coolant back up and install the valve cover. Then I can bleed the injector lines out and fire her up. Mike

Just a quick update, got her the rest of the way back together. Had to deal with a few minor fuel leaks from injector lines that didn't want to seat down and seal but I got them squared away. Took her out and worked her good in some tall field grass. After a good working, the blow by goes away to nearly nothing. And each time I restart from cold, it returns but less and less the more I run her. The overheating has stopped. With only 1641 hours on the meter, I think with some more use, it will subside to minimal level. She sure sounds better now. Mike
