(sorry for my lack of terminology) The part above the fuel filter, that has the bleeder and primer, its making a nasty noise when you turn the key on (before and after starting the motor itself) Id describe it as a fan like noise. The motor runs drives fine, just making that noise. Tried to bleed it nothing came out. I ordered a whole new unit but just wondering if anyone had input. Thanks! |

Howdy Turbo - Welcome to LOST might want to start with the Noob guide http://www.lostjeeps.com/forum/phpBB3/viewtopic.php?f=5&t=54207 lots of good information and links in there. generally that part that the filter attaches to - is called a Fuel head (although a couple of older Diesel folks have said Fuel Manager) the new unit fixes a significant problem - so it's a good idea (and comes with a new filter) The only moving parts on that are the manual pump and vent valve - so in order for it to be making a noise - you'd have to have a huge air leak (the entire fuel system is a vacuum - from engine to tank) and I doubt that it would run. I suspect the source of a 'fan like noise' is the other side of the engine - specifically the turbo hoses. if you haven't put in a Provent or EHM (Noob guide) then the interior of your turbo hoses are coated with oil and they will fail - occasionally with a pop, sometime with a slow split starting at the bottom - generates a air whistle - still runs - but less and less power as the leak gets bigger. |

Update: Seems to be in the liberty diesel throttle control valve body |

Commonly referred to as the FCV (PN 5142799AA) which has an internal plastic gear that tends to strip out which is probably your noise. I know you can remove the butterfly with no harm but what I don't know is if you can open the unit up and remove the gear. If others say that's ok then I'd do so. |
