ok, My totally stock 1973 914 1.7FI is whining. It starts up fine and sounds normal. but as soon as you get the RPMs up over 1500rpm, something starts making a whining sound and it is a throttle sensitive sound. Almost like a gear drive sound, but not as extreme. Once the sound starts, it doesn't go away, even at idle. I have no idea what it could be. The car runs fine, buit has recently started burning oil and smoking a bit. Please offer any suggestions!!!

That makes perfect sense actually because the sound first started right after I used my car to jump start a dead battery. I could tell it was loading up the generator pretty hard. Thanks! |

First lets check the stuff that does not cost money. With the engine OFF, reach your hand inside the fan and see if you picked up something from the road. I have picked out pieces of plactic sheeting a few times. Make a heck of a noise. |

QUOTE this was your first mistake!!!! That makes perfect sense actually because the sound first started right after I used my car to jump start a dead battery. I could tell it was loading up the generator pretty hard. Thanks! I don't jump start any vehicle...........with a stock 914 electrical system their too sensitive.......I think you toasted your Alternator....and whatever else?? |

Throw out bearings can make a whining noise.They could also be sensitive to higher revs when they are going bad.
