i have noticed that my engine makes this very high squeking noise and i think thats the problem am i right? also after i have been driving awhile and come to a stop my oil needle starts to go crazy and the oil pressure sign lights up but its not due for an oil change whats goin on there? any help is greatly appreciated thanx

 

what are your miles on the truck, what year, what motor?

My guess is you are 70K+ on a 2000 5.4...

anyways sounds like either a belt or pulley is squeaking. if its one of the pulleys it could be not spinning like it should, and it may be causing the belt to slip. Does it smell like rubber when you drive it for a while?

its a 97 xlt with around 120,000mi ive never had a rubber smell while driving

 

Probably a pulley had my tentioner pully break off while i was driving home one night. It also had the sqweek to it
