I have a 97 F-150 with the 4.6 V8 and I am about to do a compression test on my truck because it is burning quite a bit of oil. What should the numbers be? It only has 106000 miles on it.

 

Not sure what the max compression should be but they all should be within 95% of each other. You may also want to do a leak down test. Max compression is one thing but compression dropping is what will really show what is going on in the cylinders and valves.
