The engine is a 54 235, it still runs good but the oil pressure is getting low and a blue snake is coming out the tail pipe when I step on the gas.I see some Stovebolters run engines with shims.But remember back, there was a discussion(heated),saying shimmmed engines are "junk".The machine shop tells me shimmed 235 engines are not a problem, he used to do a lot of them.What do you say?
Porky Pig is just a ham.
| | | | | | Anonymous Unregistered | | Anonymous Unregistered | Your 54 235 is a " Cast Iron Wonder ". Everyone wonders why they run so long. Build that motor right & you wont have to worry 'bout it again !!

However, a good machinist can grind the crank to match a set of bearings. It takes a little more work, since the bearings must be set in place, miked, then the crank ground. Must crank grinders simply grind to specs in a manual.
