    I just changed the timing belt, thermostat, waterpump and spark plugs on my 03 CTS with the 3.2L at 100k miles. I made sure all the vacuum lines were good before starting and it started up. There is a loud diesel like sound/tapping sound. Please help

    I would check your belt again, make sure it's lined up properly. I would definitely not start that engine again until you can validate the belt is installed correctly.

    scary stuff, the timing could be off on one of more cams. how was the idle when you started it first time? and did any new codes show up? IIRC These engines have 2 cam sensors and a crank sensors that might throw a code if the timing is off

    note: if you didn't know this already the alignment marks on the belt will not line up with the alignment marks on cams after the first revolution, however the alignment tool work fine.
    think on the bright side, the timing belt is a lot easier to replace than a timing chain on 3.6L

    i am beyond overwhelmed. im 19 and can literally do anything on a jeep but this is my dads CTS and this is a huge disappointment. i hate this cadillac and want to crush it with my jeep. nothing aligns. im going to throw it all back and let a mechanic deal with this POS car

    ----------

    great news.. while working on it, the cams slipped. yay so what, is my engine done for?

    well even after the cams slipped, i was able to realign everything and throw it all back together. the diesel sound remains but no real signs of bent vales. hmmm
