85 bronco 2 compression

Hi

Just wondering what the compression on a 85 2 bronco should be.I think it a 4.0 engine,the bronco had been siting for 3or2 years in a bone farm looks like the plugs are floulded with oil.Just thought i would do a compression test. thanks

An 85 should have a 2.8, I would expect 120-140, within 10-15% of each other. Do you have any blue smoke, that would indicate oil burning. Are all the plugs the same? How many miles?
