have a engine knock and i cant figure out what it is... The jeep has 107000 miles on it and it's a 2002. 3.7 v6. It's in the upper left side of the engine almost sounds like the alternator is making the noise but it's deeper then that. any help or idea would be greatly appreciated! thanks in advance. |

Old trick to help isolate the area... take a screwdriver and hold the handle end to your ear and the other end onto valve cover, altenator or whatever else. |

is it ticking, clacking, tapping, deep knocking noise. might just be a lifter or could have thrown a rod. hows your oil? |

If the sound is a TICKING like a sewing machine, I had a timing chain tentioner stick on Towstrap's 02 ! There are three timing chain's and each has a tentioner that is hydrolic, and can get cloged !! |
