1992 Ford Tempo with engine rattle
Someone please help me! My engine has an incredibly bad rattle/knock in the valves somewhere. I replaced the plugs and found them to be really curroded and changed the distributor cap and rotar. There is pressure in the valve compartment and there is not much vacuum coming from the air intake. Air is blowing out of oil cap hole when I take it off. It rattles when there is a load; i.e. whne I am idling in drive. When it is in neutral there is little rattle. If you have any ideas, please let me know.
