I have a 51 Vac that makes a chirping noise after the engine warms up a couple minutes. I have a solid 110 pressure in all cylinders and I disconnected the fan belt from the engine so I can eliminate the water pump and a fan pully.
Last fall I noticed smoke coming from the valve covers and shut the engine down. I then seized up and I let it sit all winter. This spring it unseized but started the noise. My fear is I have spun a main bearing and not sure where to go from here. It ran very well last summer and no water in the oil when I changed it.
Anything else I should look at before I consider a new engine? Would it be asking for more problems to replace the main bearings? Or am I looking at a complete engine teardown only to find the block is no longer any good. Anybody have good results just replacing bearings? What would something like this cost? Thanks for any guidance.
