    Alright heres my symptoms,

    smoke on startup when cool

    sweet smelling exhaust

    very low coolant (i filled it back up)

    nasty gunk all over the block by the rear pass sparkplug

    not alot but a tiny bit of water in the pass tailpipe

    engine stumbles until its warm


    What do you think?

    Thanks Again

    Jonathan

    could be cracked head, cracked block, or most likely a blown head gasket.

    the oil on the head by the plug is most likely from a leaky vavle cover gasket.

    I would guess that you probably have a blown head gasket.

    Put a pressure test on it...Go to Autozone, Advance, whatever and rent a pressure tester.

    Cracked block is an awfully serious problem to be jumping to the conclusion of.... :confused:

    like he said, test your compression. Is it only on one side or is it both??

    I dont know when the water is there but its not very much. Everything is happening on my passenger side, and i have true duals so i am only seeing water and smoke on one side.

    I ONLY get smoke on startup tho, out of the pass. tailpipe
