I have a 91 Crown Vicotoria with a 5.0 litre engine. I did a compression test on it and all cylinders were reading between 80 and 90 psi. Are the heads gone or the block???
when you do the compression test you should do it dry and wet . add a little oil through the spark plug hole to seal the rings and see if the compression changes.If it changes then you could have wore rings.If it dosnt you can do a cylinder leak down test to check the valves.
