I have a 1994 F-150, with the Inline six-cylinder engine. Is it possible to oil the bearing on the distributor, it has started to squeak at idle.

 

Hey there and welcome to the Forum! Just an FYI.... Any internal piece of an engine needs lubriction to operate properly. If you know for sure the Shaft/bearing/bushing isn't receiving any lubrication, it's an indication the there isn't any lubriction going on elsewhere in the upper part of the engine as well. Since gravity plays a large part in the oil going back to the oil pan, and there isn't any oil going to the top of the engine....

Oil level- Oil pressure ok. Oil pressure should be 40-60psi.@2000 rpm. If all ok....
There may be a blockage of some type that needs further investigation. Yes, you'll have to remove the valve cover. I don't know if you feel comfortable in doing this or you would rather take it to your mechanic to have checked out.
But it does seem that you have a problem and you can't let it go very long. This is an extremly urgent situation, unless, you have the money for a total engine rebuild! I wouldn't drive it, or run the engine for that matter, until it has been looked at and the problem located then fixed. Just my opinion though.

All I can say is.... No part of the internals of an engine should produce a SQUEAK/SQUEAL/THUD/THUNK/PING, or any other noise that can be described by slang or other terms it takes to describe a noise! Get back to us with a bit more info or if you've discovered the problem. Thanks and we'll talk with you later....
