So, I think I siezed a lifter... Small block Chevy crew

    I took the valve covers off today, and one of the rockers for #3 wasn't moving. I pulled the rocker off and held the pushrod in there, to see if I could feel the lifter moving. It's stuck in the up position.

    Is there any way to un-seize the lifter? What causes this? How can I prevent it from happening again?

    What year motor? Sure you didn't wipe out a lobe on the cam?

    Stuck in the "up" position? It was holding the valve open? I can't picture it, unless some hard debris in the lifter oil galley is jammed against the lifter body.

    Seems damn unlikely. :dunno:

    It's possible there is enough gunk and varnish that it's holding it in the bore but there is no way it would be in a full "up" position or the piston would be kissing the valve every revolution ..

    That depends on the compression ratio. At least as far as I know, only the Europeans routinely make interference engines -- everyone else knows they're too expensive to warranty.

    the lifter is up, as in, trying to push the valve down?



    maybe the lifter was thrown too high and is now wedged in the lifter galley.... then the insides broke letting the valve back up?

    No, I didn't say that. I said it would only cause damage if it's an interference engine. I didn't say a thing about whether it actually was.

    Sounds more like a broken valve spring...

    if it has domed pistons that engine would be toast right now if the valve was stuck open

    Ah. So then it must not be an interference engine after all.

    Either that, or it is an interference engine, and he over-revved it, but it just bent the valve instead of breaking it off, and that's why the valve can't close.

    It was actually going OK until you claimed only high compression engines would have valve to piston issues with open valves. Don't even get me started on your "only europeans make interference engines" bullshit. :rofl::rofl::rofl::rofl::rofl:

    I didn't say anything about high-compression either; try reading my post again, this time paying attention to the words in it.

    Yes, high-compression engines are usually interference engines, but a low-compression engine with unusually-high valve lift can also be an interference engine.

    Americans make interference engines too? Well, that's a point against them then, unless they at least use timing chains instead of timing belts.

    more like the europeans, americans, and japanese. most Honda engines are interference.

    FUCKING A DUDE!! READ THE FUCKING THREAD TITLE .. SEE THAT?! SMALL BLOCK CHEVY CREW ... do you know what the fuck a small block Chevy is?? I'll clue you in, it's a fucking old school RWD V8 engine made by Chevrolet. It's not some fucking I4/I6/horizontally opposed import/eurotrash fucking bullshit. Get your fucking interference vs non interference and timing chain vs timing belt bullshit and take it the fuck out of this thread, it has NOTHING TO DO WITH SMALL BLOCK CHEVYS. NOW YOU HAVE A FUCKING CLUE. FUCKING HALLELUJAH. HOLY SHIT!! WHERE'S THE TYLENOL?!

    I guess everyone I know who's popped a timing belt got lucky and bought a car without an interference engine then. Whatever.

    Yes, I know what a small-block Chevy is. The timing belt vs. timing chain thing was in regards to American engines in general; I know small-blocks have either chain or gear drive on their one central camshaft, except when fitted with overhead cams anyway. As for whether it's an interference engine, of course that applies; you say it is one, another guy says it might be or might not depending on the piston profile.

    In any event, if you know so much about it, stop arguing with me and lay out the facts in black and white. I can't argue with you if all you say is "the engine specs are such-and-so, therefore these are the possible problems".

    Why would you use a belt drive if there is any other option? It's far less durable.

    The LT5 has dual overhead cams. Look here.
