('99 Cavalier 2.4, 115K) Has a pretty loud engine ... 'slap', I'd call
it. (It had a 'tick', but this is loud enough to be embarrasing to
drive.)

We had a similar problem last summer. I listened to the rocker arms
with a stick, and found one that matched the noise. And, I could rotate
that push rod (no others) with my fingers. So, I 'flushed' the engine
oil, and the noise dropped to a tolerable 'tick'.

That was then. This time, that rocker arm itself is way loose - there's
close to 1/8" of play.

So: how much adjustment can a lifter take up? Can a stuck lifter cause
that much play, or would that mean that the lifter is dead?

Thanks,
George

Do you mean a 2.2? the 2.4 DOHC doesn't have rocker arms.

Well it could be a bad lifter. The guts are close tolerance and small
chunks of crud can clog the valve and oil feed.

Yeah, 2.2. (I remember it as "not what I think it is," and I used to
think it was a 2.0. I guess that means my memory is improving?)

It's pretty definitely the lifter. The question I have is whether to
bother trying the oil flush thing, or just go to plan B.

Could be a worn down cam.

An eighth of an inch, overnight?

Assuming it is the lifter, can a 'stuck' lifter (ie, one that can
possibly recover) be down that far? Or, (assuming it is the lifter),
would it needed to be hopelessly damaged.

I just don't want to bother doing the flush-and-drain thing, if there's
no point.
