I have used grease in the past. Never will go back to that. Grease is extremely messy.Always just filled the hole with grease then found something close to the hole size and gave it a smack with a hammer. This seems a bit less messy.
Might even work better, but bread is ubiquitous. I don't have another flywheel removal in my future to try it out.Wonder if silly putty would work? Just couldn't bring myself to waste food like that. (It is a really good idea though.)
Got nominated to hook up everything under thr belly pan of a D11 when after we rebuilt the engine and torque converter... threw those clothes out after that day. My pants could stand up on their own.. bad day6 liter Internatinal leaking injector lines beneath the intake manifold on the "Critter Getter" rear loading garbage truck, hmm hmmm gooood. Hydraulic leaks above the brooms of a sweeper, welding inside the tank of a vactor (turd herder), packer cylinders on a side loader.............I could make a real tasty list. A different kind of messy, But retirement has cleaned my boots and I don't have to chase rats out of my play area any longer or wonder what just dripped down my neck. Did it all for fun.
