    Bent intake valves

    Hello all!
    I have a 2000 Saturn LS1 2.2 that had the timing chain slip and bent all the intake valves. The valves put small marks in the pistons but no cracks that i can tell. My question is can I replace just the valves and timing set and be good to go. The engine has 147,000 miles but ran good before the chain slipped.
    Thanks, Keith

    As long as the pistons aren't cracked and what not, yes. However, if there are small marks on the piston which you mention this will likely cause hotspots on these areas on this piston which will eventually lead to bad pistons...which could cause more problems.
    And an LS1 saturn, that thing must haul

    you know the intake valves are bent...

    Probably hurt the valve seats, and guides...

    I'd say by the time you get the head rebuilt, gaskets, labor involved...

    You'd be better off buying a junkyard motor...

    LS1 is what they called the l200 (or is it the L100) for the first year or two they existed, then they changed the name to avoid the confusion with the engines.

    The more i think about the more i think a junk yard or used engine is the way to go. What year ecotec engines would be a direct bolt-in for my car. Like i said mine is a 2000 Saturn 2.2 with the EGR ready head. I'm not aware of the differences throughout the years.

    they all have the egr ready head... but do you actually have an egr? If so please tell me the color of the wires leading to it, it would make many people who tune ecotec cars jump for joy, even more if you could trace that wire (the one that doesnt go to ground, ie the one thats not black) back to the pcm connector and post what pin number it is.

    I believe any eco from before 2005 will work, but I believe if you get one out of a cavalier or sunfire you'll need to swap oil pans as I believe the oil pan on the L-series are different than all the other ones.
