hey i have a 1999 ford ranger 3.0. just recently a chirping sound started coming from my engine. i replaced the fan clutch, the idler pulley, tensioner pulley, and belt. and the chirp still comes back. when i spray wd40 anywhere on the pulleys the sound goes away for a while. help i don't know what else it could be!

 

Check your camshaft sychronizer asap,it can waste your engine.

 

how do i check that

 

You would be best off to replace the cam sync and sensor. Use only motorcraft parts for this.

 

X2 ^^^ I bought mine on eBay.
